Refer to Figure 4-6. The 1.0 U.S. gallon (3.79 liter)
hydraulic reservoir is located in front of the engine and
under the operator’s platform.
Hydraulic Reservoir
Figure 4-6
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more
often if system appears to be leaking or otherwise
malfunctioning.
Fluid level should be 1” from top of reservoir. Use only
SAE 10W40 SG, SF/CC, CD service motor oil.
Refer to Figure 4-6. Change hydraulic system filter
element (Land Pride P/N 831-030C) 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
(Land Pride P/N 821-041C). This additive, available from
your Land Pride dealer, will increase the performance life
of the hydraulic system components.
The system filter is located to the right of the hydraulic
reservoir. A standard oil filter wrench is used to change
filter, threads are right handed. Use Land Pride
approved filter element P/N 831-030C only.
Replace filter element as follows:
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 turn with a 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.

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.
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.
IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only motor oil as
specified. Remember, dirt is the primary enemy of
any hydraulic system.
IMPORTANT: Each hydraulic pump is equipped with
a bypass valve. For additional information refer to
Operating Section, “Moving Mower with Stalled
Engine” page 11.

bypass valves. Refer to “Moving Mower with
Stalled Engine” on page 11 for more information.
