6 - WORKING OPERATIONS

Liquid ballast (Optional)

It is a common practice to add weight to the tractor by fill-

ing the rear tires with liquid. A calcium chloride (CaCl2)

and water solution is recommended due to the low freez-

ing point and greater density (weight per gallon) than pure

water.

Never exceed the total recommended weight for the trac-

tor. Because special equipment is required to fill the tires,

consult your dealer. Tires should never be filled beyond

75 %. At 75 % full, the liquid will come to the valve stem

(1) when the valve stem is at the highest point, at the top

of the wheel.

DANGER

Explosion hazard!

Welding to a wheel can create an explosive air

and gas mixture. Removing air from the tire or

loosening the tire on the wheel (breaking the

bead) will NOT eliminate the hazard. ALWAYS

remove the tire completely from the wheel be-

fore welding.

Failure to comply will result in death or serious

injury.

D0033A

WARNING

Explosion hazard!

When inflating tires, use a clip-on air chuck

with a gauge, remote valve, and hose long

enough to allow you to stand to one side and

NOT in front of or over the wheel assembly.

Keep others out of the DANGER AREA. Never

inflate a tire beyond the maximum allowable

pressure printed on the tire.

Failure to comply could result in death or se-

rious injury.

W0059A

WARNING

Explosion hazard!

Do not remove, install, or make repairs to a tire

on a wheel rim. Take the tire and rim to a tire

shop where persons with special training and

special safety tools are available.

Failure to comply could result in death or se-

rious injury.

W0365A

Upon receiving your tractor, check the air pressure in the

tires and recheck every 50 hours or weekly. Refer below

table for tire pressure for normal operation.

See the tables for tire pressure and permissible load for

more details.

When checking tire pressures, inspect the tires for dam-

aged tread and side walls. Incorrect pressure will lead to

premature tire failure.

Do not exceed the load for the pressures listed. Do not

over-inflate or under-inflate the tire.

To avoid the possibility of tire creep (movement of the tire on the rim), tire pressure below 90 kPa (13 psi) should

not be used with cross ply tires 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 up to 6 km/h (4 mph).

For haulage service, it is recommended that the tire 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

tires, consult your dealer.

7 - MAINTENANCE

Refueling the Tractor

The fuel tank filler cap (1) is located at the rear of the front

hood. Before removing the cap, wipe all dust and dirt from

around the cap to prevent debris from falling into the tank

while filling.

Use an approved fuel container and check the inside of

the container periodically for cleanliness. Fuel tank ca-

pacity is 51 l (13.5 US gal)

NOTICE: The fuel cap is a vented-type. Use only an ap-

proved NEW HOLLAND replacement cap to prevent fuel

system-related problems.

If there is no filter on the storage tank or fuel container,

20108795

filter the fuel through a 100-mesh or finer screen when fill-

ing the tractor fuel tank. Keep the tractor tank as full as

possible (without filling to capacity) to minimize conden-

sation.

NOTICE: It is a good practice to fill the fuel tank at the end

of each day, as this will reduce overnight condensation.

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 galvanized 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.

20108796

3. Keep the tank slightly tilted so that the sediments will

settle away from the outlet pipe. To facilitate moisture

and sediment removal provide a drain plug at the low-

est 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.

Engine oil level

1. 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.

GNIL14TR00519AA

2. Pull out the dipstick from dipstick port. (1) see figure 2

3. Check the oil level by means of the dipstick (1) see

figure 1.

4. If the level is below minimum mark, add fresh oil (1) see

figure 2 until oil level is between the two marks on the

dipstick.

GNIL14TR00523AA

NOTICE: Do not fill above the upper maximum line on dipstick. Excessive oil will be burned off within a short time

and give a false impression of oil consumption.

Engine cooling system

WARNING

Burn hazard!

Hot coolant can spray and scald if you remove the radiator or deaeration tank cap while the system

is hot. To remove the cap: allow the system to cool, turn the cap to the first notch, and wait for all

pressure to release. Remove the cap only after all pressure has released.

Failure to comply could result in death or serious injury.

W0367A

7-13

7 - MAINTENANCE

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 off. An

additional water tank is fitted fill the coolant in the tank

by removing tank cap (1).

GNIL14TR00517AA

NOTICE: Never use tractor without radiator cap (1) as this will result into boiling and hence evaporation of the engine

coolant.

Steering oil reservoir level

1. Check the oil level through the transparent reservoir

(1). .

2. If level is low, add NEW HOLLAND AMBRA MULTI G

134™ HYDRAULIC TRANSMISSION OIL as required.

Fuel injectors - servicing

CAUTION

Escaping fluid!

Hydraulic fluid or diesel fuel leaking under pressure can penetrate the skin and cause infection or

other injury. To prevent personal injury: Relieve all pressure before disconnecting fluid lines or per-

forming work on the hydraulic system. Before applying pressure, make sure all connections are tight

and all components are in good condition. Never use your hand to check for suspected leaks under

pressure. Use a piece of cardboard or wood for this purpose. If injured by leaking fluid, see your

doctor immediately.

Failure to comply could result in minor or moderate injury.

WARNING

Hot liquid under pressure!

Service when cool.

Failure to comply could result in death or serious injury.

W1187A

NOTICE: It is essential that a genuine approved pressure cap is used. If the cap is misplaced or damaged, obtain a

replacement from your Authorized NEW HOLLAND Dealer.

1. Open the radiator drain plug (1) and allow the coolant

to drain.

(Drain cock is on the rear, left-hand side of

the radiator). Remove the radiator pressure cap to in-

crease the drainage rate.

GNIL14TR00525AA

2. After draining, flush the cooling system with clean water

through the radiator filler. When the flushing process is

complete, refill the cooling system with a 50/50 solu-

tion of ethylene glycol antifreeze and water through the

radiator until the coolant is 20 mm (0.79 in) below the

neck of the radiator tank. Re-install the pressure cap.

NOTE: To avoid trapping air in the system, fill the radiator as slowly as possible thereby allowing any formation of air

pockets to disperse.

NOTE: The coolant level may drop as the coolant is pumped around the cooling system.

3. If the engine is not going to be operated immediately

following this coolant change, run the engine for one

hour to ensure that the water is distributed throughout

the cooling system. Allow the engine to cool and make

a final check to ensure that the water level is satisfac-

tory.
