4 - OPERATING INSTRUCTIONS

Moving the unit

Steering - Operation

The tractor has a hydraulic steering system which provides convenience when operating the steering wheel. A non-

load reaction system keeps the steering wheel from moving when the impact of the front wheels travel over rough

ground.

Operating notes

• If there is too much of a load in the front bucket, it could be difficult to operate the steering wheel. In this case,

reduce the size of the load or move the tractor slowly forward while turning the steering wheel in the direction of

desired travel.

• After turning the steering wheel fully, do not turn the steering wheel fully to the same direction again. Unnecessary

force is applied, which could damage the steering system.

NOTICE: Do not hold the steering wheel fully to the left or right for more than 10 seconds, it could cause a failure

in the steering system.

• If an abnormal sound is heard while operating the steering wheel, this means that there is some air in the steering

components line. In this case, turn the steering wheel to left and right fully and hold for about 5 seconds. The air

should bleed out and the abnormal noise should go away. If the sound does not go away take your tractor to your

authorized NEW HOLLAND dealer.

• When operating the tractor in cold weather, the abnormal sound may be heard. In this case, warm up the tractor

before using to reduce the oil viscosity.

• If you use the tractor for a long period of time while turning the steering wheel fully, the oil temperature will increase

which may cause the reduction of the product life or the failure of the hydraulic steering system.

NOTE: If the engine stops, the hydraulic power for the steering system will stop. The loss of hydraulic power will

make the steering wheel hard to turn.

W1247A

The tractor hydraulic oil also serves as the tractor transmission fluid. During cold weather operation, the hydraulic

oil viscosity increases. This increase in oil viscosity restricts the oil's ability to flow and lubricate in the transmission

and hydraulic circuits. The cold oil can result in abnormal noises and slower operation times due to the increased oil

viscosity.

NOTE: A warm up time at 50% rated engine speed is recommended to assure proper vehicle functionality, transmis-

sion lubrication and operation.

NOTE: Do not operate the tractor under full load condition until the hydraulic oil is sufficiently warmed up.

General information

Ballasting the tractor

For sufficient traction and maximum performance in heavy draft operations and to counterbalance rear-mounted equip-

ment weight should be added to the tractor in the form of cast iron weights or rear mounted ballast box. Only enough

weight should be added to provide good traction and stability. Adding more weight than is needed results in unnec-

essary soil compaction increased rolling resistance and higher fuel consumption.

NOTE: When adding weight to the tractor tire pressures may need to be increased. See7-23 in this manual.

Front end ballast may be required for stability and steering control when weight is transferred from the front wheels

to the rear wheels as an implement is raised by the tractor three-point hitch.

Use the following as a general guide:

• Ballast the tractor (less implement) so that approximately one-third of the tractor weight is on the front wheels. For

optimum traction tractors equipped with 4WD should be ballasted so that 40 - 45% of machine weight is on the

front wheels.

• When a rear mounted implement is raised to the transport position the front wheel reaction should be at least 20%

of tractor weight.

• Add additional front end ballast as required for stability during operation and transport. Tractor front end ballast may

not always maintain satisfactory stability if the tractor is operated at high speed on rough terrain. Reduce tractor

speed and exercise caution under these conditions.

• When using front-mounted equipment add weight to the rear axle to maintain good traction and stability. Front-

mounted equipment varies in weight. Refer to equipment manual for ballasting.

Weighting limitations

The weighting limitations that follow are limitations only. They do not imply that the tractor should be weighted to attain

the weights given. Use only enough weight to obtain good performance.

Adequate lubrication and maintenance on a regular schedule is vital to maintaining your equipment. To ensure long

service and efficient operation, follow the lubrication and maintenance schedules outlined in this manual. The use of

proper fuels, oils, grease and filters, as well as keeping the systems clean, will also extend machine and component

life.

NOTICE: While any company can perform necessary maintenance or repairs on your equipment, NEW HOLLAND

strongly recommends that you use only authorized NEW HOLLAND dealers and products that meet the given speci-

fications. Improperly or incorrectly performed maintenance and repair voids the equipment warranty and may affect

service intervals.

NOTICE: Always use genuine NEW HOLLAND replacement parts, oils and filters to ensure proper operation, filtration

of engine and hydraulic systems. See your NEW HOLLAND dealer for additional oil quantities.

Regular lubrication is the best insurance against delays and repairs. Proper lubrication will extend machine life. Refer

to the chart on page 7-8 for lubricants and service intervals.

NOTICE: Failure to complete the required maintenance at the recommended intervals can cause unnecessary down-

time.

The intervals listed in the Lubrication Chart are guidelines to be used when operating in normal conditions. Adjust

the intervals for operating in adverse environmental and working conditions. The intervals should be shortened for

sandy, dusty and extremely hot operating conditions.

Always clean the area around dipsticks, fill caps, and check plugs when checking fluid levels. Failure to clean these

areas may allow contamination to enter the system. Drain, flush and refill the system any time you suspect it is

contaminated.

Grease Fittings

Wipe dirt from fittings before greasing.
