Change hydraulic system filter element (Fig. 12-5) after first 50 hours
of tractor operation, then replace filter and oil in reservoir every 500 hours
thereafter. When changing hydraulic oil use 1/2 unit (approximately 3.5
oz.) of Lubrizol additive (Hustler P/N 027912). This additive, available
from your Hustler dealer, will increase the performance life of the hydraulic
system components.
The system filter is located directly in front of the hydraulic reservoir.
A standard oil filter wrench is used to change filter, threads are right
handed. Use a Hustler approved filter element only.
IMPORTANT: Prefill the filter element with clean oil, before
installing, to prevent drawing air into the system pump.
1. Fill the filter element with clean system oil. Smear a light coating of
oil on upper surface of rubber seal.
2. Install the filter element on base. Tighten the oil filter by hand until
the filter seal makes contact with the filter head, then tighten an
additional 3/4 - 1 turn with an oil filter wrench. — DO NOT
OVERTIGHTEN.
3. Start tractor engine and let run at approximately 2/3 throttle for a few
minutes to work any trapped air out of the system before engaging
the steering control lever.
4. Stop the engine and check the filter and connections for leaks.
5. Check the hydraulic reservoir for specified oil level. Add clean oil
as necessary.
Clean or replace hydraulic reservoir cap annually. Cap may be cleaned
by dipping in or flushing with cleaning solvent. Follow manufacturer’s
instructions and warnings for application of solvent type selected.
The hydraulic oil heat exchanger is designed to keep the hydraulic
system oil temperature lower in hot operating conditions or heavy
continuous operating conditions.
This hydraulic heat exchanger is located above the engine. Air is drawn
across the cooling fins by an electric fan located above the heat exchanger.

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.
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. (Fig. 12-7) Total
capacity for the fuel tanks is 15 U.S. gallon (56.8 liter)
Use regular unleaded gasoline with an octane rating of 87 or higher.
The fuel filter (Fig. 12-8) is installed in the fuel line between fuel tanks
and engine fuel pump. Replace filter annually or after every 500 hours of
operation, whichever occurs first.
When replacing the fuel filter, check the fuel line hoses and fuel shut-
off valve grommet for any cracks or leaks. Replace as needed.
Hustler ATZ tractors are equipped with a fuel shutoff valve located on
the right fuel tank mount (Fig. 12-9). Rotate the valve to the middle
position (shown) to prevent fuel flow to the fuel pump. The forward
