SECTION 1 GENERAL INFORMATION AND SAFETY

TO THE OWNER

SAFETY

GENERAL

Pages 5 to 9 include the list of precautions to be observed to ensure your safety and the safety of others. Read the safety precautions and follow the advice offered before operating the tractor.

This Manual has been prepared to assist you in the correct procedure for running--in, driving and operating and for the maintenance of your new tractor. Your tractor, which was designed to power and propel itself, is intended for use in normal and customary agricultural applications. Read this Manual carefully and keep it in a convenient place for future references. If at any time you require advice concerning your tractor, do not hesitate to contact your Authorised Dealer. He has company trained personnel, genuine manufacturers’ parts and the necessary equipment to carry out all your service requirements. Your tractor has been designed and built to give maximum performance, economy and ease of operation under a wide variety of operating conditions. Prior to delivery, the tractor was carefully inspected, both at the factory and by your dealer to ensure that it reaches you in optimum condition. To maintain this condition and trouble--free operation, it is important that the routine services, as specified in Section 4 of this manual, are carried out at the recommended intervals.

CLEANING THE TRACTOR When cleaning the tractor, particularly if using a high pressure washing machine. precaution has to be taken to safeguard electrical / electronic components and connections. The pressure generated by some of these machines is such that complete protection against water ingress cannot be guaranteed. While washing the tractor, using a high pressure washing machine, do not stand too close to the tractor and avoid directing the jet at electrical connections, breathers, seals, filler caps, etc. Never direct a cold water jet at a hot engine or exhaust.

FIRST 50 HOUR SERVICE After you have operated the tractor for 50 hours, take your tractor, together with warranty booklet to your dealer. He will then perform the manufacturer recommended 50 hour service and complete the service report. Ensure the completion of the coupon and signature of Service Manager/Dealer.

SERVICE PARTS It should be pointed out that genuine parts have been examined and approved by the company. The installation and/or usage of ‘non-genuine’ products could have negative effects upon the design characteristics of your tractor and thereby affect it’s safety. The Company is not liable for any damage caused by the use of ‘non--genuine’ parts and accessories. Only Genuine New Holland replacement parts should be used. The use of non-genuine parts may invalidate legal approvals associated with this product. It is prohibited to carry out any modifications to the tractor unless specifically authorised, in writing, by the After Sales Service department of the Company.

ECOLOGY AND THE ENVIRONMENT Soil, air and water are vital factors of agriculture and life in general. Where legislation does not yet rule the treatment of some of the substances which are required by advanced technology, common sense should govern the use and disposal of products of a chemical and petrochemical nature. The following are recommendations which may be of assistance: •

•

Become acquainted with and ensure that you understand the relative legislation applicable to your country. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, cleaning agents, etc., with regard to their effect on man and nature and how to safely store, use and dispose off these substances.

HELPFUL HINTS

3. Modern oils contain additives. Do not burn contaminated fuels and/or waste oils in ordinary heating systems. 4. Avoid spillage when draining off used engine coolant mixtures, engine, gearbox and hydraulic oils, brake fluids, etc. Do not mix drained brake fluids or fuels with lubricants. Store them safely until they can be disposed off in a proper way to comply with local legislation and available resources. 5. Modern coolant mixtures, i.e. antifreeze and other additives, should be replaced every two years. They should not be allowed to get into the soil but should be collected and disposed off safely. 6. Repair any leaks or defects in the engine cooling or hydraulic system immediately.

1. Avoid filling tanks using open containers or inappropriate pressurised fuel delivery systems which may cause excessive spillage.

7. Do not increase the pressure in a pressurised circuit as this may lead to the component exploding.

2. In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of them contain substances which can be harmful to your health.

8. Protect hoses during welding as penetrating weld splatter may burn a hole or weaken them, causing the loss of oils, coolant, etc.

SECTION 1 -- GENERAL INFORMATION AND SAFETY DRIVING THE TRACTOR

1. Always sit in the driver’s seat while starting or driving the tractor. 2. When driving on public roads, have consideration for other road users. Pull in to the left side of the road occasionally to allow any following traffic to pass. Do not exceed the legal speed limit set for agricultural tractors. 3. Dip the tractor lights when meeting a vehicle at night. Make sure the lights are adjusted to prevent blinding the driver of an oncoming vehicle. 4. Reduce speed before turning or applying the brakes. Brake both wheels simultaneously when making an emergency stop. Ensure that both brake pedals are locked together when travelling at road speeds or when on public roads ensure correct operation of trailer brakes.

7. Any towed vehicle whose total weight exceeds that of the towing tractor must be equipped with brakes for safe operation. 8. Never try to apply the differential lock when turning. When engaged, the differential lock will prevent the tractor from turning. 9. Always check overhead clearance, especially when transporting the tractor. Watch where you are going, especially at row ends, on roads and around trees and low overhanging obstacles. 10. To avoid overturns, drive the tractor withcareand at speeds compatible with safety, especially when operating over rough ground, when crossing ditches or slopes and when turning corners.

5. Use extreme caution and avoid hard application of the tractor brakes when towing heavy loads at road speeds. 6. Keep the tractor in the same gear when going downhill as would be used when going uphill. Do not coast or freewheel down hills. 11. Use extreme caution when operating on steep slopes. 12. If the tractor becomes stuck or the tyres are frozen to the ground, reverse the tractor out to prevent overturning.

SECTION 1 -- GENERAL INFORMATION AND SAFETY OPERATING THE TRACTOR

1. Apply the parking brake, place the P.T.O. control in the ‘OFF’ position, the lift control lever in the down position, and the transmission levers in neutral before starting the tractor. 2. Do not start the engine or operate controls while standing beside the tractor. Always sit in the tractor seat when starting the engine or operating the controls. 3. Do not bypass the transmission neutral start switches. Consult your authorised dealer if your neutral start controls malfunction. 4. Use jump leads only in the recommended manner. Improper use can result in a tractor runaway on its own or causing damage to the battery.

10. Do not run the tractor engine in an enclosed building without adequate ventilation. Exhaust fumes are toxic and can cause death. 11. Pull only from the pick-up hitch, swinging drawbar or the lower link drawbar in the lowered position. Use only a drawbar pin that locks in place. Pulling from the tractor rear axle or any point above the axle may cause the tractor to overturn. 12. Always select Position Control when attaching equipment andwhen transporting equipment. Be sure hydraulic couplers are properly mounted and will disconnect safely in case of accidental detachment of the implement.

5. Avoid accidental contact with the gear shift levers while the engine is running. Unexpected tractor movement can result from such contact. 6. Do not get off the tractor while it is in motion. 7. Before leaving the tractor, park the tractor on level ground, apply the parking brake, lower attached implements to the ground, disengage the P.T.O. and stop the engine. 13. If the front end of the tractor tends to rise when heavy implements are attached to the three--point hitch, install front end weights. Do not operate the tractor with a light front end. 14. Engage the clutch slowly when driving out of a ditch, gully or up a steep hillside. Disengage the clutch promptly if the front wheels rise off the ground.

8. Do not park the tractor on a steep incline. 9. Do not operate the tractor with parking brake applied

15. Ensure any attached equipment or accessories are correctly installed, are approved for use with the tractor, do not overload the tractor and are operated and maintained in accordance with the instructions issued by the equipment or accessory manufacturer.

Do not use your hand to check for leaks. Use a piece of cardboard or paper to search for leaks. Stop the engine and relieve pressure before connecting or disconnecting lines.

Tighten all connections before starting the engine or pressurising lines.

10. Dispose of all drained fluids and removed filters properly. 11. Tractor wheels are very heavy. Handle with care and ensure, when stored, that they cannot topple and cause injury. DIESEL FUEL

1. Under no circumstances should gasoline, alcohol or blended fuels be added to diesel fuel. These combinations can create an increased fire or explosive hazard. In a closed container such as a fuel tank these blends are more explosive than pure gasoline. Do not use these blends. 2. Never remove the fuel cap or refuel with the engine running or hot.

3. Do not smoke while refuelling the tractor or when standing near fuel. Keep any type of open flame away.

If fluid is injected into the skin obtain medical attention immediately or gangrene may result.

4. Do not fill the fuel tank to capacity. Fill only to the bottom of the filler neck to allow room for expansion.

7. Do not modify or alter or permit anyone else to modify or alter the tractor or any of its components or any tractor function without first consulting an Authorised Dealer.

5. Wipe up spilled fuel immediately. Always tighten the fuel tank cap securely.

•

8. Continuous long term contact with used engine oil may cause skin cancer. Avoid prolonged contact with used engine oil. Wash skin promptly with soap and water.

6. If the original fuel tank cap is lost, replace it with an approved cap. A non--approved cap may not be safe. 7. Never use fuel for cleaning purpose.

9. Keep equipment clean and properly maintained.

FUEL SAVING TIPS FOR OPTIMUM OUTPUT Proper maintenance of Tractor reduces fuel consumption to a greater extent.

8. Follow the running--in procedure given in this manual for optimum performance of your tractor.

1. Store fuel in properly cleaned, rust and contamination free containers.

9. Do not run the engine in idle condition for more than twominutes. It mayresult in wastage of fuel.

2. Always fill the tank at the end of each day to reduceovernight condensation of moisture in the air, in turn to avoid damage to the fuel system.

10. Do not rest your foot on clutch pedal, as this will cause clutch slippage, loss of engine power and increased fuel consumption. Maintain the specified cluctch pedal free play.

3. Fuel filters should be replaced as per recommended time schedule as the filtering capacity is not retained after this specified time. It may allow harmful contamination and damage the fuel injection system. Follow the service schedule for draining the water from the filters and cleaning the feed pump filter. 4. Always use genuine fuel filters available from your Authorised Dealers. 5. Stop diesel leakage, if any, immediately. 6. Dirt particles entering the engine causes early wear of liners and piston rings, resulting in loss of power, engine oil & fuel consumption. Clean the pre--cleaner bowl daily and change the air cleaner oil as mentioned in service schedule. Ensure that there is no leakage through hoses and the air cleaner bowl seal is in good condition, keep hose clamps tight. 7. Check the Radiator coolant level daily and top--up with clean water only. Radiator fins should always be kept clean. Should it be necessary to replace radiator cap, use only genuine cap of the specified pressure . Never try to remove the thermostat. Check and adjust fan belt tension regularly. Ignoring these, will result in engine over heating and heavy diesel consumption.

1--16

11. Always drive the tractor in proper gear. 12. Use a lower gear while driving down a slope and use brakes sparingly. 13. Maintain proper tyre pressures for field work as well as for roadwork. Refer the tyre pressure chart given in this manual. Worn out tyres causes wheel slippage and waste fuel. Re--tread or replace the tyres if they are badly worn out. Adhere to tyre ballasting as and when required to reduce wheel slippage and fuel consumption. 14. Always use matching implements to cut down the diesel wastage. Implements should be maintained in good condition, as usage of worn out implements will waste fuel. 15. Always plough length wise and plan your field run to reduce fuel consumption. Adjust the wheel track to suit the implement and avoid overlap when working in the field. 16. When using a PTO driven equipment, operate the engine at the recommended speed to reduce fuel consumption.

SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION Differential Lock Pedal Figure 11

It is recommended to lock the differential by depressing the pedal (1) in the following cases: •

•

1

During ploughing, to reduce slippage of the landside wheel. When one of the rear wheels loses grip due to uneven, muddy or loose soil.

WARNING

11

Applying the differential lock essentially lock the rear wheels causing them to run at the same speed. Differential lock should therefore never be engaged in transport at speeds of more than 8 km/hr. or when turning.

IMPORTANT: If a rear wheel spins at more speed than theother, reduce the engine speed before trying to engage the differential lock. This will avoid shock loads and the risk of damage to the internal components. Clutch Pedal Figure 12

When the clutch pedal (1) is depressed, the drive between the engine and the transmission will be disengaged. Use the clutch pedal to transfer engine power smoothly to the rear wheels when moving off from a stationary position. Always depress the clutch pedal before engaging or disengaging a gear. NOTE: Do not use the clutch pedal as a footrest when driving the tractor. Such action will lead to clutch slippage and premature clutch failure.

HYDROSTATIC STEERING (if fitted) IMPORTANT: Never hold the steering wheel against either of the steering stops (full lock) for more than 10 seconds or for more than a total of 10 seconds in any one minute. Failure to observe this precaution may result in damage to the steering system components.

Front--wheel drive can increase the tractor’s grip on the surface; the benefits of this are particularly noticeable when working on uneven, muddy or slippery surfaces, on ploughed ground or in difficult conditions.

Front--wheel drive engagement / disengagement is carried out by means of lever (1) fig. 19 when the tractor moving slowly and preferably at the low speeds of the engine.

18

Avoid carrying out this operation under stress. If the maneouvre proves to be difficult with the tractor moving in a straight line, keeping the lever in engaged position, slightly turn the steering wheel in bothdirections until the control mechanism engaged.

CAUTION Do not use front wheel drive on hard surfaces to prevent premature wear to the front tyres. Abnormal tyre wear can also be caused by incorrect tyre pressures. To engage front--wheel drive push the lever (1) fig. 19 backward

SECTION 3 -- FIELD OPERATION

SECTION 3 FIELD OPERATION BEFORE OPERATING

CAUTION Before driving or operating the tractor, study the safety precautions in Section 1 of this manual. Read this section carefully for a thorough understanding of operational requirements. Even if you operate other tractors, you should thoroughly read this section of the manual and ensure that you are familiar with the location and function of all the controls of this tractor. Do not start the engine or attempt to drive or operate the tractor until you are fully accustomed with all controls. It is too late to learn once the tractor is moving. If in doubt about any aspect of operation of tractor, consult your Authorised Dealer. See Section 4 for lubrication and maintenance requirements. Tractor specifications will be found in Section 7.

SECTION 3 -- FIELD OPERATION RUNNING--IN PROCEDURE

PRE--OPERATION CHECKS

Your tractor will provide long and dependable service if given proper care during the first 50--hours running--in period and if serviced at the recommended intervals.

Before operating the tractor, ensure that you are thoroughly familiar with the location and operation of the controls.

Avoid overloading the engine. Operating in a high gear under heavy load may cause engine overloading. Overloading occurs when the engine will not respond to a throttle increase. Do not operate the engine without a load. This can be as harmful to the engine as overloading. Ensure that the engine is subjected to heavy as well as light loads during the running--in period.

Perform daily lubrication and maintenance operation in accordance with Section 4. After completing the daily maintenance operations, perform a walk around visual inspection of the tractor. Pay particular attention and check the following items: i.

Fan belt for cracks.

ii. Engine area for accumulation of debris. Use the lower gears when pulling heavy loads and avoid continuous operation at constant engine speeds. Operating the tractor in a low gear with light load and high engine speed will waste fuel. You will save fuel and minimise engine wear by selecting the correct gears for particular operation. Check the instruments frequently and keep the radiator and various oil reservoirs filled to the recommended levels.

3--2

ii. Hoses, lines and fittings for leaks and damages. iv. Tyres for damage. v.

Hardware for looseness.

vi. Leakage at joints. Make any necessary repairs before using the tractor.

SECTION 3 -- FIELD OPERATION TOWING THE TRACTOR IMPORTANT: The tractor should only be towed a short distance, such as out of a building. Do not tow on roadways or as a method of transport. IMPORTANT: If it is necessary to tow the tractor, all gear levers must be moved to the neutral position before stopping the engine otherwise damage to transmission components may occur during towing. If creeper gears (reduction gear set) are fitted, then the selector control must be in the off position.

CARRYING THE TRACTOR ON A TRANSPORTER Transport the tractor with all four wheels on a flat bed trailer or truck. Securely chain the tractor to the transporter. IMPORTANT: Do not chain around the four wheel drive shaft, steering cylinders, front wheel drive axle or other components that could be damaged by contacting the chain or by heavy loading.

Use the drawbar hanger for a rear tie down point. Use a strong chain when towing the tractor. Tow the tractor from the rear using only the drawbar, rear tow hitch or the three--point hitch. Tow the tractor fromthe front using the tow pin in the front weights or front support. Have an operator steer and brake the tractor. To avoid damaging the transmission or other components that turn but are not lubricated during towing, observe the following •

Only tow a short distance

•

Keep speed below 5 MPH (8km/h)

•

If possible, run the engine to provide lubrication to the transmission and power steering.

CAUTION Do not tow the tractor faster than 8 Km/h (5MPH). The steering is much slower and steering wheel effort is much greater without the engine running.

WARNING Do not use cables or rope to tow the tractor. If the cable or rope breaks or slips, it may whip with sufficient force to cause serious injury. When using a chain, attach the chain with the hook open side facing up. If the hook slips, it will drop down instead of flying up. NOTE: Four wheel drivewillbe engaged if theengine is not running, regardless of the position of the 4WD activation lever.

POWER TAKE--OFF Figure 6

The power take--off (P.T.O.) transfers engine power directly to mounted or trailed equipment through a splined shaft (1) at the rear of the tractor. The P.T.O. system is independent, that is, the P.T.O. may be engaged or disengaged whether the tractor is moving or stationary. Rotation of the P.T.O. shaft is not affected by the main clutch and tractor speed but is related directly to the speed of the engine.

1

6

The system utilises the standard 6--splines shaft designed to operate at 540 rpm, the speed at which most P.T.O. driven equipment is designed to run. The standard 540 rpm is obtained at 1967 engine rpm.

Figure 7

The P.T.O. is engaged or disengaged by means of lever (1).

1

Description

The three point linkage enables semi--mounted and fully mounted implements to be connected to the tractor, and be controlled by the tractor hydraulic system. The linkage consists of two lower links (1) connected to the rear axle housing. The rear end of the lower links are connected to the lower hitch pins on the implement.

2

1 14

The lower links are raised and lowered by means of the lift rods (2) connected to the lift arms . The RHlift rod is readily adjusted to ease the attachment of implements and to level the implement after attaching. The top link (3) is connected to a bracket on the hydraulic lift housing. The rear of the top link should be connected to the upper hitch pin of a mounted implement. The top link is also adjustable to aid implement setting.

WARNING Always use Position control Lever when attaching, detaching or transporting equipment, when no equipment is attached to the tractor, or at any time when not actually using the Draft control Lever.

ATTACHING 3 --POINT EQUIPMENT Figure 15 & 16

Most equipment can be attached to the tractor as follows: 1.

Position the tractor so that the lower link hitch points are level with and slightly ahead of the implement hitch pins. Carefully bring the tractor rearwards to match the tractor and implement hitch points. First attach the left lower link, then by adjusting the levelling box, attach the right lower link.

CAUTION

15

Engage the parking brake before leaving the tractor to make the connections.

3--13

SECTION 3 -- FIELD OPERATION 2. Lengthen or shorten the top link until the implement mast pin can be inserted through the mast and upper link of the implement. 3. Connect remote cylinders (if fitted). 4. When detaching equipment, the procedure is the reverse of attaching. The following hints will make detaching easier and safer. •

•

•

Always park the equipment on a level, firm surface. Equipment should be supported so that it cannot tip or fall when detached from the tractor. Always relieve all hydraulic pressure in any remote cylinders before detaching (if fitted).

IMPORTANT: When attaching mounted or semi mounted equipment to the three--point linkage, ensure that there is adequate clearance between the implement and the rear of the tractor. The clearances in the raised position should be checked by raising the implement carefully with Position control Lever. With the implement fully raised there must be at least 100 mm. clearance between the implement and the nearest part of the tractor.

LIFT RODS, LOWER LINKS AND TOP LINK

CAUTION Before disconnecting a lift rod from the lower link, stop the engine and lower the attached equipment to the ground. Ensure attached equipment is correctly supported and that no pressure remains in the hydraulic system before removing the lift rod securing pin. Move the hydraulic lift control levers fully down in order to relieve any remaining pressure.

When adjusting lift rods length, ensure that at least 40 mm of thread remains engaged with lift rod tube.

SECTION 3 -- FIELD OPERATION Position Control Operation Figure 32

Position control provides accurate control of implements such as sprayers, rakes, rotary tillers etc. that operate above the ground. Once set, Position control will maintain the selected implement height. IMPORTANT: Always set the system to Position control at any time when not actually operating in Draft control, such as when attaching or transporting equipment or when no equipment is attached.

3 1

2 32

Move draft control lever (1), fully forward. Set implement position below or above ground by moving lever (2) forward to lower and rearward to lift. Implement movement will be proportional to lever travel. An adjustable stop (3) is provided to enable the lever to be returned to the required working position. Draft Control Operation

Figure 33 1 Draft control is most suitable for mounted or semi--mounted implements operating in the ground. Changes in the working depth or changes in soil resistance will cause draft loading on the implement to increase or decrease. When starting work, fully open the Response control valve and move the Position control lever (2) fully forward. Lower the implement in to the work using Draft control lever (1). Push the lever forward to increase the draft loading. Pull rearwards to reduce the draft loading. Forward movement of the Draft control lever will increase the implement depth and rearward movement will reduce the depth. Once set, tractor hydraulic system will automatically adjust the implement depth to maintain an even pull on the tractor and minimise wheel slip

SECTION 3 -- FIELD OPERATION Front Wheel Toe--in Figure 48

After resetting the track width, the front wheel toe--in may require adjustment. For correct operation, the front wheels should be parallel or toe--in slightly. To measure the toe in proceed as follows: IMPORTANT: Incorrect toe--in setting may result in abnormal wear of front tyres.

Measure the distance(1) between the wheel rims at hub height at the front of the wheels. Rotate both front wheels 180 and check the measurements again, this time at the rear of the wheels (2). This will eliminate wheel rim run--out errors. The correct toe--in setting is 0 -- 5 mm, i.e. the measurement taken at the front of the rims should be the same as the rear or be smaller by up to 5 mm.

48



Should it be necessary to adjust the front wheel toe--in, proceed as follows: Figure 49

2 Remove the nut (1) at the right end of the track control rod and withdraw track control rod from arm (2). Loosen the bolt (3) and rotate the threaded end to shorten or lengthen track rod assembly until the toe--in is correct. Tighten all bolts/nuts securely.

SECTION 3 - FIELD OPERATION Rear Wheel Track Adjustment Figure 50

CAUTION Tractor wheels are very heavy. Handle with care and ensure, when stored, they can not topple and cause injury. Rear wheel track adjustment is effected by changing the wheel rim relative to the centre disc, the rim and/or the disc relative to the axle hub or by interchanging the rear wheels.

B

The sectioned drawings shown in the table illustrate the wheel rim and disc positions viewed from rear of the tractor relative to the hub at various track width settings. Track width (the distance between the centre of the tyres ) are nominal and may vary by as much as 13 mm. C

IMPORTANT:

When interchanging left and right wheel assemblies, ensure the ‘ V’ of the tyre tread remains pointing in the direction of forward travel of tractor for better grip. NOTE :

With certain options and/or tyre sizes narrower track settings may not be possible due to minimal clearance between tyres and fenders or equipment.

BALLASTING AND TYRES Selecting ballast

For maximum tractor performance in heavy draft conditions weight should be added to the tractor in the form of liquid ballast, cast iron weights or combination of both.

When tractor horsepower loads vary the optimum weight of the tractor will change. This means that ballast may have to be added or removed to maintain the best tractor performance. Proper ballast will greatly improve tractor operation and ride.

Front end ballast may be required for stability and steering control when weight is transfered from the front to the rear wheels as the implement is raised by the tractor three--point linkage.

The amount of ballast required is effected by

When a rear mounted implement is raised to the transport position, the weight on the front wheels should be at least 20% of total tractor weight.

Add front--end ballast as required, for stability during operation and transport. Ballasting of the front end may not always provide adequate stability if the tractor is operated at high speed on rough ground. Reduce tractor speed and be cautious under these conditions. When using front mounted equipment, it may be necessary to add weight to the rear wheels to maintain traction and stability. IMPORTANT: Only sufficient weight should be added to provide traction and stability. Adding more weight than necessary results in unnecessary loads being put on the tractor and higher fuel consumption. When adding weight adhere to the maximum tyre capacity loading stated in the tables at the end of this Section, Page 3--36. If further information or assistance is required on tractor weighing consult your Authorised Dealer.

WARNING If proper stability cannot be achieved within the following weighting limitations, reduce the load on tractor until stability is restored

SECTION 3 - FIELD OPERATION Ballast Limitations Ballast should be limited by the tyre capacity or tractor capacity. Each tyre has a recommended carrying capacity, which should not be exceeded (see page 3-36) IMPORTANT :

Do not exceed the tractor gross vehicle weight of 2800 Kg of NH TT55 & 3600 Kg of NHTT75 model. This can cause overload condition that may invalidate the warranty and may exceed the load rating of the tyres. The maximum recommended gross vehicle weight is the weight of the tractor plus ballast plus any mounted equipment/implement in the raised position.

CAST IRON WEIGHTS (If fitted) Rear Wheel weights Figure 51 1

The rear wheels are fitted with four (NH TT55 model) & six (NH TT65/TT75 model) Cast Iron Rings (1) weighing 55 Kg each, for a total of 330 kg. 220 kg respectively on each side as an optional fitment. Additional weights may be added as required.

51

Tightening torque: Rear wheel weight to rear wheel disc : 150 Nm Rear wheel weight to rear wheel weight : 150 Nm NOTE :

Standard ballast weights should not be removed from the tractor, except for medium to deep puddling operation with full cage wheels.

LIQUID BALLAST Figure 54

Filling the rear tyres with liquid ballast is a convenient method of adding weight. Plain water is recommended in normal ambient temperature (above freezing point) or solution of calcium chloride and water is recommended in low ambient temperature (below freezing point). Solution of 0.6 Kg Calcium Chloride per litre of water will give protection from freezing down to an ambient temperature of --50 C (--58 F) 



Special equipment is required to water ballast tyres. See your Authorised New Holland Dealer for details. The Table below shows the quantity of plain water, which required for each tyre size option. Thequantity mentioned in the table will give a 75% fill of the tyre.

•

Do not exceed the load for the pressures listed. Do not over or under inflate the tyre. •

DANGER Inflating or servicing tyres can be dangerous. Whenever possible, trained personnel should be called in to service or install tyres. In any event, to avoid the possiblity of serious or fatal injury, follow the safety precautions below

•

•

•

Do not inflate steering tyres above the manufaturer’s maximum pressure shown on the tyre or beyond the maximum shown in the Tyre Pressure and Load tables if the tyre is not marked with the maximum pressure. Do not inflate a tyre that has been run flat or seriously under--inflated until it has been inspected for damage by a qualified person. Torque wheel bolts to specification after re--installing the wheel. Check nut tightness daily until torque stabilises. Refer to ‘TRACTOR BALLASTING’ section, page 3--32 before adding ballast to the tyres. Ensure the jack is placed on a firm, level surface. Ensure the jack has adequate capacity of lifting your tractor. Use jack stands or other suitable blocking to support the tractor while repairing tyres. Do not put any part of your bodyunder the tractor or start the engine while the tractor is on the jack. Never hit a tyre or rim with a hammer. Ensure the rim is clean and free of rust or damage. Do not weld, braze, otherwise repair or use a damaged rim. Do not inflate a tyre unless the rim is mounted on the tractor or issecured sothat it will not move if the tyre or rim should suddenly fail.

To avoid the possibility of tyre creep (movement of the tyre on the rim), tyre pressure below 0.9 bar should not be used with cross ply tyres for operations having a high torque requirement, e.g. sub--soiling, heavy transport, etc. When mounted implements are used on tractor, loads may be increased by 20% with no increase in inflation pressure, if operated at speeds upto 6 Kmph. For haulage service, it is recommended that the tyre be inflated to the maximum pressure stipulated in the table. The above chart is for guidance only. For exact information regarding inflation pressures and loads for your particular tyres, consult your Authorised Dealer. 3--36

LUBRICATION AND MAINTENANCE CHART The chart on page 4--6 lists the intervals when the routine checks, lubrication, service and/or adjustments should be performed. Use the chart as a quick reference guide when servicing the tractor.

FUELLING THE TRACTOR CAUTION When handling diesel fuel, observe the following: Do not smoke around diesel fuel. Under no circumstances should petrol, alcohol or kerosene be added to diesel fuel because of increased fire or explosion risks. In a closed container such as fuel tank, they are more explosive than pure petrol. DO NOT use these blends. •

Check and tighten all cooling system hose connections. Check and tighten all air intake connections. Check and torque front end weight clamp bolts (where fitted)

•

Check torque of all wheel nuts

•

Cleaning of air intake cleaner/filter

•

•

•

Important:Items listed in first 50--hours service are important. If not performed, early component failure and reduced tractor life may result.

•

PREVENTING SYSTEM CONTAMINATION To prevent contamination when changing oils, filters, etc., always clean the area around the filler caps, level and drain plugs, dipsticks and filters prior to removal. To prevent dirt entry during greasing, wipe dirt from the grease fittings before greasing. Wipe excess grease from the fitting after greasing.

4--2

•

Clean the filler cap area and keep it free from debris The fuel tank should always be topped up at end of each day to reduce overnight condensation. Never take the cap off or refuel with engine running. Keep control of the fuel nozzle while filling the tank. Don’t fill the tank to capacity. Allow room for expansion. If the original fuel tank cap is lost, replace it with genuine original cap and tighten securely. Wipe up spilled fuel immediately

SECTION 4 -- LUBRICATION AND MAINTENANCE FUEL REQUIREMENTS The quality of fuel used is an important factor for dependable performance and satisfactory engine life. Fuels must be clean, well--refined and non--corrosive to fuel system parts. Be sure to use fuel of a known quality from a reputable supplier. Use Number 2--D in temperatures above --7 C (20 F) 



Use Number 1--D in temperatures below --7 C (20 F) 



To obtain optimum combustion and minimum engine wear, the fuel selected for use should conform to the application and property requirements outlined in the following chart.

NOTE: When long periods of idiling or cold weather conditions below 0 C(32 F) are encountered or when continuously operating at an altitude above 5,000 ft. (1500 m) use Number 1--D fuel. 



Using diesel fuel with sulphur content above 0.5% requires more frequent oil and filter changes as noted in the maintenance schedule. The use of diesel fuel with a sulphur content above 1.3% is not recommended. For the best fuel economy, use Number 2--D fuel whenever temperatures allow. Do not use Number 2--D fuel at temperatures below --7 C (20 F). The cold temperatures will cause the fuel to thicken, which may prevent the engine from running (If this happens, contact your authorised New Holland dealer.) 



To be sure that a fuel meets the required properties, enlist the aid of a reputable fuel oil supplier. The responsibility for clean fuel lies with the fuel supplier as well as the fuel user.



* When continually operating at low temperatures or high altitude, a minimum cetane rating of 45 is required.

4--3

SECTION 4 -- LUBRICATION AND MAINTENANCE FUEL STORAGE Take the following precautions to ensure that the stored fuel is kept free of dirt, water and other contaminants. 1. Store the fuel in black iron tanks, not galvanised tanks, as the zinc coating will react with the fuel and form compounds that will contaminate the injection pump and injectors. 2. Install bulk storage tanks away from direct sunlight Fig. 1. Keep the tank slightly tilted fig. 2 so that the sediments will settle away from the outlet pipe. 1 3. To facilitate moisture and sediment removal provide a drain plug at the lowest point at the end opposite the outlet pipe. 4. If fuel is not filtered from the storage tank, put a funnel with a fine mesh screen in the fuel tank filler neck when refuelling. 5. Arrange fuel purchase so summer grade fuels are not held over & used in winter.

2

FILLING THE FUEL TANK Clean the area around the fuel filler cap to prevent dirt from entering tank and contaminating the fuel. Remove the cap and place in a clean area during refuelling. After filling the tank, replace and tighten the fuel cap. Important: Always replace a lost or damaged cap with a genuine, original equipment replacement cap. Fuel Tank Capacity -- 62 Litres

EVERY 10 HOURS OF OPERATION OR DAILY (Which ever occurs first) Carry Out the following checks: OPERATION 1 Check Engine Oil Level Figure 5 & 6

Before checking the oil level, ensure that the tractor is on level ground, stop the engine and wait for a short period to allow the oil to drain back into the sump. 5

Check the oil level by means of the dipstick (1). If the level is below min. mark, top up with fresh oil after removing the filler cap. Fill the oil from filler plug (1) fig 6.Do not fill above the upper (max.) line. Excessive oil will be burned off within a short time and give a false impression of oil consumption. See Section 7 for the correct oil specifications and quantity.

CAUTION To avoid personal injury, always keep your body parts away from the silencer manifold. 6

OPERATION 2 Check Radiator Coolant Level Figure 7

Peak power operation, followed by a rapid reduction in power requirement and engine speed, may cause the coolant to boil and be discharged from the radiator overflow tube. Normally, this loss of coolant is small and of little consequence, but repeated loss can significantly lower the coolant level and necessitate topping up. NOTE: Never use tractor without radiator cap(1) as this will result into boiling and hence evaporation of water.

Figure 8

The function of the pre--cleaner is to remove chaff, straw and the larger airborne material before the air passes to the air cleaner itself. Loosen the clamp (1) and remove the pre--cleaner (2). Clean and dry the complete pre--cleaner assembly and re--install.

2 8 OPERATION 4 Clean Air Cleaner Oil Bowl Figure 9

The oil bath air cleaner should be checked daily, or more often when working in extremely dusty conditions. The function of Air Cleaner is to remove impurities from the air but at the same time allow sufficient volume of air to enter the engine, to ensure complete burning of the fuel. The air cleaner will only fulfil this function if it is correctly and regularly maintained. A poorly maintained air cleaner means loss of power, excessive fuel consumption and a reduction in engine life. Release the four over centre catches to loosen the grip on the air cleaner bowl (1). Remove the bowl assembly and gauzefilter (2). Visually check the condition and level of oil in the inner cup of the bowl. If there is sediment collected, drain the oil and clean the inner cup and bowl with cloth and re--fill to the level mark. Do not fill above the level mark.

SECTION 4 -- LUBRICATION AND MAINTENANCE PROTECTING THE ELECTRONIC AND ELECTRICAL SYSTEMS DURING BATTERY CHARGING OR WELDING Precautions

To avoid damage to the electronic/electrical systems, always observe the following: 1. Never make a break in any of the charging circuit connections, when the engine is running. 2. Never short any of the charging components to earth. 3. Do not use a slave battery of higherthan 12volts nominal voltage. 4. Always observe correct polarity when installing the battery or using a slave battery to jump start the engine. Follow the instructions provided in Section -- 3, Page 3--4 in this manual. 5. Always disconnect the earth cable from the batteries before carrying out arc welding on the tractor or on any implement attached to the tractor. 6. Position the welder earthcable clamp as close to the welding area as possible. 7. Never allow welding cables to lay on, near or across any electrical wiring or electronic component while work is in progress. 8. Always disconnect the negative cable from the batteries when charging the batteries in the tractor with a battery charger.

WARNING Batteries contain sulphuric acid. In case of contact with skin, flush the affected area with water for five minutes. Seek medical attention immediately. Avoid contact with the skin, eyes or clothing. wear eye protection when working near batteries.

Maintenance of the Battery

1. Batteries should not be allowed to discharge completely. If the tractor is to be stored for a period of more than 2 weeks, the battery should be removed from the tractor and stored in dry location in a wooden platform. Trickle charge every 2 to 3 weeks to maintainthe battery ingood condition. 2. Ensure that theelectrolyte level in all battery cells is preferably at the maximum level. However, in general, the level should be between minimum and maximum marks. Add distiled water, if the electrolyte level is found below the minimum level. Do not use well/tap water. Do not top up with acid. 3. The specific gravity in every cell of the battery should ideally be between 1.260 -- 1.230. At any point of time, specific gravity in cells should not fall below 1.230. If the reading is below 1.230, then the battery shows symptoms of a discharged battery. Please refer it to your Battery Dealer. 4. Always apply the battery terminals with petroleum jelly (Vaseline) to avoid current leakage and rusting. Never use grease for the same purpose. 5. Always disconnect the earth terminals (negative terminal) of the battery, while carrying out any repairs on the tractor, especially during welding. 6. Do not crank the engine for more than 10 seconds at one time. Wait for about 30 seconds and then crank again. 7. Never take any burning object or flame near the battery. 8. Check tightness of battery securing clamps periodically. Do not over--tighten as this may damage the battery case.

Important:

Starter Motor

Protection of the Alternator

1. Starter motor mounting nuts should be tight.

1. Before carrying out any operation on the alternator please disconnect the battery.

2. Give sufficient time between consecutive starts.

2. Never check the working of the alternator by connecting positive and negative terminals. 3. Do not run the alternator without battery in the circuit. 4. Do not use high voltage bulbs as warning light.

4--34

3. Do not run the starter motor for more than 10 seconds 4. Do not run the starter motor without any load. 5. Do not run the starter motor with discharged battery.
