Incorrect air cleaner element
Use only the correct Donaldson air filter element, Hustler
part number 785261, which is designed to fit the canister
properly.
Hustler air filter elements have the correct media
composition, filter area, micron size and dimensions.
Always use genuine Hustler filters. Many aftermarket
filters have been found to be incompatible with Hustler's
canisters and engines.
The air filter must remain intact to block passage of dirt
and foreign particles from entering the engine. Being
inclined to disbelieve the need for more expensive air filter
elements used on diesel engines may cause some individuals
to opt for a less expensive part.
The filter element must be sufficient size and
construction to withstand stresses, caused by rapid cycling
of the air volume demanded by the engine, without cracking
or tearing under fatigue and pressure (especially diesel
engines). Therefore, Hustler Turf Equipment and the engine
manufacturers have carefully selected a reliable filter
designed to fit the needs of the engines. The filter specified
is a Donaldson filter, Hustler part number 785261.
Owners should be reminded that failure to use original
equipment replacement parts is an "alteration" and will not
be considered for warranty in the event of engine damage.
Recommended service procedure
1. Release clamps and remove element. Clean the
canister with a damp cloth.
2. Before installing a new element, inspect it by placing a
bright light inside and rotate the element slowly,
looking for any holes or tears in the paper. Also check
gaskets for cuts or tears. Do not attempt to use a
damaged element which will allow abrasive particles
to enter the engine.
3. Reinstall the dust cup. Make sure it seals all the way
around the air cleaner body, then tighten the clamps.
4. Check all fittings and clamps periodically for tightness
and inspect hoses for holes or cracks.
5. Periodically check the intake hose for signs of ingested
dust. Locate and repair the source of ingested dirt.
6. Never operate a machine without an air filter installed.

Cooling system

Engine cooling is accomplished with circulated water and
Ethylene Glycol mixture. The radiator is equipped with a
pressure cap and recovery tank. System capacity is
approximately 3.0 U.S. gallon (11.36 liter). A 50-50
mixture is recommended for all season operation. This
mixture provides freeze protection to -32 degrees F (-35
degrees C). Should temperatures fall below this level,
additional Ethylene Glycol must be added to the mixture.
Visually inspect the system daily prior to operating
tractor. Check coolant level in the recovery tank located to
the front left of the radiator assembly (Fig. 4-15). When the
engine is cold there should be 1" (2.54
recovery tank. When adding coolant, pre-mix the solution
before adding it to the recovery tank. It is not necessary to
remove radiator cap for adding small amounts of coolant to
system.
The system should be drained, flushed and refilled with
fresh solution after every 500 hours of operation.
If frequent refilling is necessary or if coolant appears
