Hustler Turf 4300 - Manual (Page 32)

The engine hood at rear is hinged. To raise it, unfasten
the two latches and tilt hood up and forward. A hood
support rod is stored clipped to the bottom side. Insert this
rod in the hole provided in the rear support on right side
(Fig. 5-10).
Access to the hydraulic reservoir and pumps is gained by
pulling forward on the spring latch (located at the front of
the operator’s seat platform) and tilting the seat up and
forward.
Hydraulic system
IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only motor oil as
specified. Always keep quick-release couplers capped when
separated and wipe them clean before connecting.
Remember, dirt is the prime enemy of any hydraulic system.
WARNING: Hydraulic oil escaping under
pressure can penetrate skin. Before applying
pressure to hydraulic system, make sure all
connections are tight and all hoses and lines are
in good condition. To find a leak under pressure,
use a piece of cardboard or wood – never use
your hands. Lower all attachments and shut off
engine before opening any hydraulic lines.
The 3.5 U.S. gallon (13.2 liter) hydraulic oil reservoir is
located under the tractor seat platform (Fig. 5-11).
Check level of oil in hydraulic system after every 100
hours of tractor operation or monthly, whichever occurs
first. Check more often of system appears to be leaking or
otherwise malfunctioning.
Fluid level should touch the bottom of screen under filler
cap. Use only SAE 10W40 SG, SF/CC, CD service motor
oil.
Change hydraulic system filter element after first 50 hours
of tractor operation, then replace filter and oil in reservoir
every 1000 hours or annually, whichever occurs first. When
changing hydraulic oil use one unit (approximately 7 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.
Filter is located to the left of reservoir and is accessible
from underneath (Fig. 5-12). A standard oil filter wrench is
used to change filter, threads are right handed. Use a 10
micron, 700 psi filter element only.
IMPORTANT: Fill the filter element with clean oil,
before installing, to prevent drawing air into the system
pumps.
1. Fill the filter element with approximately 1.8 pints
(0.82 liter) clean system oil. Smear a light coating of
oil on upper surface of rubber seal.
2. Install the filter element on base, tighten 1/2 turn after
initial gasket contact - DO NOT OVERTIGHTEN.
3. Start tractor engine, engage the hydraulic pump clutch
and let it run at approximately 2/3 throttle for a few
minutes to work any trapped air out of the system
before stroking the wheel motor control levers.
4. Disengage the pump clutch lever, stop the engine and
check the filter and connections for leaks.
5. Check hydraulic reservoir for specified oil level. Add
clean oil as necessary.
NOTE: The hydraulic pump is equipped with tow valves.
For more information refer to Operation section, Moving
tractor with stalled engine.
Fuel system
WARNING: Observe usual fuel handling
precautions; do not smoke while refueling, do
not fill tank with engine running or while engine
is hot; allow engine to cool before storing
machine inside a building, keep fuel away from
