• Start the engine and run for about 5 minutes.

Stop the engine and check for leaks at the oil

filter and drain plug.

• Wait 3 minutes and re-check the oil level. If

needed, add oil to bring the oil level up to the

"FULL" mark.

WARNING: Never overfill the engine

crankcase. The engine may overheat

and/or damage may result. For best

results, fill to the “FULL” mark on the

dipstick as opposed to adding a given

quantity of oil. Always check the level

on the dipstick before adding more oil.

Dispose of used oil in an environmentally

safe manner. If necessary, contact your

area EPA office for proper disposal

procedures and recycling center locations.

IMPORTANT: The oil fill cap and dipstick must

always be installed securely in place when the

engine is running. Severe engine damage could

result from failure to do so.

CHECKING ENGINE COOLANT LEVEL

Before each use, the engine coolant level in the

overflow reservoir should be checked to ensure it is

within the operating range. Engine coolant absorbs

heat from the engine and transfers the heat to the

air flowing through the radiator. If the coolant level

becomes low, the engine may overheat, which

could cause severe damage to the engine.

Use a permanent type antifreeze containing corro-

sion and rust inhibitors. Dilute the antifreeze with

water at a 1:1 ratio to mix the coolant solution (50%

antifreeze : 50% water).

NOTE: Distilled water is recommended for the cool-

ant solution IF your tap water has a high mineral

content. Minerals cause scaling in the engine and

the radiator coolant passages. System efficiency

will be greatly reduced over time and severe engine

damage may result.

• Check the coolant level when the engine is cold

and the tractor is on a level surface.

• Raise the tractor hood and check the coolant

level in the overflow reservoir on the right side of

the engine. Refer to Figure 52.

• If the coolant level is below the "LOW" mark,

remove the cap from the reservoir and add

coolant solution to the "FULL" mark.

NOTE: The cooling system is a closed type.

Normally, to prevent air from entering the system,

the radiator cap should not be removed.

If the overflow reservoir is empty, the radiator cap

should be removed and the coolant level in the radi-

ator checked before adding coolant to the reservoir.

If necessary, first refill the system through the radia-

tor filler neck as follows (Refer to Figure 48):

WARNING: It is dangerous to remove

the radiator cap when the system is

hot. Allow the system to cool before

removing the radiator cap.

• Turn the radiator cap counterclockwise to the

first stop to release any pressure.

• Push downward on the cap and turn counter-

clockwise until the cap stops then lift cap off.

• Slowly pour coolant into the filler neck until the

level reaches the bottom of the filler neck

overflow flange.

• Wait a few minutes to allow as much air as

possible to escape through the filler neck, then

reinstall the radiator cap.

• Fill the overflow reservoir to the "FULL" mark.

• Start the engine and allow it to run for a short

period. Stop the engine.

• Recheck the coolant level in the overflow

reservoir and refill as needed. Reinstall the

reservoir cap.

INSPECTION OF COOLING SYSTEM HOSES

Check the cooling system hoses and fan belt for

any cracks or deterioration after every 100 hours of

operation. Check for loose hose connections.

Replace any damaged hoses and tighten any loose

connections. Replace a worn or damaged fan belt.

CHANGING THE ENGINE COOLANT

The engine coolant should be drained and replaced

with new coolant solution yearly.

The dry capacity of the cooling system is

approximately 5.3 Qts. Dilute the antifreeze with

water at a 1:1 ratio to mix the coolant solution (50%

antifreeze : 50% water).

Change the engine coolant as follows:

• Drain the coolant when the engine is cold.

• Place the tractor on a level surface and raise the

tractor hood.

• Slide the overflow reservoir upward and off the res-

ervoir bracket to access the radiator drain plug.

• Locate the radiator drain plug in the lower right

rear corner of the radiator. See Figure 53.
