whichever comes first. NOTE: The filter guard must be removed to access
filter.
Each transaxle's filter is located per Fig. 4-3. A standard oil filter
wrench is used to change filter, threads are right handed. Use a Hustler
approved filter element only.
IMPORTANT: Purging procedure must be followed after changing the
oil and filter. Refer to Parts Manual (Hustler P/n 107652) for more detailed
oil changing and purging information.
WARNING: When washing the mower, direct the spray
away (especially if using a power washer) from the Hydro-
Gear ZT 2800 transaxle's seals to prevent water intrusion and
to ensure component performance.

Fuel system

DANGER: Observe usual fuel handling precautions:
Do not smoke while refueling.
Do not fill tank with engine running or while engine is hot.
Clean up any gasoline spills.
Allow engine to cool before storing machine inside a
building.
Keep fuel away from open flame or spark and store machine
away from open flame or spark if there is fuel in the tank.
Use extra caution when handling gasoline and other fuels.
They are flammable and vapors are explosive. A fire or
explosion from gasoline can burn you and others and can
damage property.
Refuel outdoors preferably, or in well ventilated areas.
Never attempt to start engine when there is a strong odor of
gasoline fumes present. Locate and correct cause.
Store gasoline in an approved container and keep it out of the
reach of children. Never buy more than a 30 day supply of
gasoline.
Always place gasoline containers on the ground away from
your vehicle before filling.
Do not fill gasoline containers inside a vehicle or on a truck
or trailer as interior carpets or plastic truck bed liners may
insulate the container and slow the loss of any static charge.
When practical, remove equipment from the truck or trailer
and refuel the equipment with its wheels on the ground. If
this is not possible, then refuel the equipment on the truck or
trailer using a portable container and not a gasoline dispenser
nozzle. If a gasoline dispenser nozzle must be used, keep the
nozzle in contact with the rim of the fuel tank or container
opening at all times until fueling is complete.
Read and observe safety precautions elsewhere in this
manual.
WARNING: Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors can cause serious injury and
illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or conditioner
opening.
Keep gas away from eyes and skin.
The fuel tanks are located in the tractor's fenders.
Use regular unleaded gasoline with an octane rating of 87 or higher.
IMPORTANT: Never use methanol, gasoline containing methanol, or
gasohol containing more than 10% ethanol because the fuel system could be
damaged. Do not mix oil with gasoline.
A fuel shut-off valve is located on each tractor. The location and
operation of the fuel valve will vary depending upon the unit. Close the
fuel valve to prevent fuel flow to the engine. The valve's two other
positions will allow fuel to be drawn from either one or the other fuel tank.

IMPORTANT: Do not overfill the fuel tanks. The fuel tanks should
be filled no higher than 2" (5.08

Engine oil and filter

Check engine oil daily and after every 4 hours of operation. Tractor
must be setting level when checking oil. Refer to engine manual and
maintenance schedule for oil recommendation and capacities.
Change the engine oil and filter after the first 5 hours of operation, per
the engine manufacturer's recommendations after that. If tractor is being
operated in extremely dirty conditions, then it is recommended oil be
changed more frequently.

Engine air filter

Perform engine air filter maintenance per the Service Interval chart
shown elsewhere in this manual.
A specially designed dry filter is standard equipment on these tractors
and supplies clean combustion air to the engine. Fig. 4-5
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.
