When storing the unit at the end of the operating season, the
following steps should be taken to ensure readiness for the
next season.
IMPORTANT: Any maintenance operation that requires
the removal of safety covers must be performed by a trained
service technician.
1. Remove all grass, dirt, and trash from power unit and
mower. Clean power unit and mower and touch up all
scrapes with Hustler spray paint.
IMPORTANT: Wash the machine with a mild deter-
gent and water. Do not pressure wash the machine.
Avoid excessive use of water
2. Install new air filter per Engine Owner's Manual.
3. Check thoroughly for any worn or damaged parts that
need replacing and order them from your dealer.

the lift arms hydraulically to their fully raised position
so that the lift cylinder is fully retracted. This will
protect the cylinder rod surfaces from corrosion.

hydraulic system and front axle with new oil.
6. Block power unit up so weight is off tires.
7. Do not deflate tires.
8. Perform separate engine preparation as listed below.
9. Store power unit in a clean, dry place.
10. Remove the battery from machine
a. Clean battery
b. Check the electrolyte level
c. Charge the battery, if necessary
d. Store battery in a cool, dry place (do not expose to
freezing temperatures)
e. Always keep the battery fully charged. (Especially
important to prevent battery damage when the
temperature is below 0

shutdown. Special diesel fuel system flushing oils are
available from most oil companies. If this oil is not
available, mix 0.5 liters of SAE 10 non-detergent
engine oil with 10 liters of No. 2 diesel fuel. Drain the
fuel tank and pour 7 liters of the special flushing oil (or
lubricating mixture) into the fuel tank. Run the engine
for 10 minutes to ensure complete distribution of the
special oil through the injection pump and fuel
injectors. There is no need to remove the injector
nozzles.
6. Fill the fuel tank with No. 1 diesel fuel. IMPORTANT:
Do not use No. 2 diesel fuel, for winter storage,
because of wax separation and setting at low
temperature.
7. Open the drain valve on the radiator. Flush the system,
close the drain valve and fill with a 50/50 solution of
permanent antifreeze and clear water..
8. Clean exterior surface of engine. Spread a light film of
oil over any exposed metal surfaces of engine that are
subject to corrosion.
9. Clean dirt and chaff from radiator fins and muffler.
10. Check oil filler cap and fuel tank cap to make certain
they are securely in place.
11. Refer to engine manual for more information.

New season preparation

storage, the following servicing is required:
1. Clean power
accumulation.
2. Check engine oil level and common sump (for the
hydraulic lift, transmission, front axle and power
steering) and the rear axle.
3. Install a fully charged battery.
4. Check the cooling system for proper level of 50/50
solution of anti-freeze and clear water.
5. Tighten any bolts that have loosened and make sure all
hair pins, cotter pins and clevis pins are in place.
6. Install all safety shields and review safety precautions
listed in this manual.
7. Check and inflate tires to 96-124 KPA.
8. Refer to engine manual for more information.
9. Start the engine and allow it to idle a few minutes. Be
