DANGER
Hydraulic fluid under pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin, it must be treated by a
doctor within a few hours or gangrene may result.
!
WARNING
Always wear adequate eye protection when servicing the
hydraulic system.

located beneath the seat. These units are self contained
and maintenance free except for changing oil and filters.

Hydraulic Oil Level Check
Refer to Figure 5-9:
Hot oil expands, therefore, check hydraulic oil level only
when it is cold. The left side is independent from the right
side. Make sure you check and fill oil as needed on both
sides. Oil level should be about 1/8" deep in the bottom of
expansion tank when cold. Add hydraulic oil to the tank if
no oil is present. Do not overfill. See page 76 for
hydraulic oil specifications.
IMPORTANT: Do not use a high pressure washer
on or around the hydraulic transaxles. Water
intrusion will result and void the warranty.
NOTE: Make certain to place the control arms in the
park position before rotating the seat platform up.
IMPORTANT: Repairs to a transaxle unit should be
performed by trained technicians only.
NOTE: The transaxle units are equipped with bypass
valves for the purpose of moving the mower when
engine is inoperable.

Transaxle Oil and Filter Change
The mower has two independent hydrostatic transaxle
systems. Each system will require separate oil and oil
filter changes. It is best to change oil soon after using the
mower while dirt particles are still suspended in the oil.
See page 76 for transaxle oil specifications.
Initially, change oil and oil filters after the first 25 to 50
hours of operation. Thereafter, change oil and filters
every 200 hours or every year whichever comes first. Two
filters are required with each oil change. They may be
purchased from your nearest Land Pride dealer. See
page 76 for filter part numbers.
1.
Park unit on a flat level surface. Stop engine and
remove ignition key. Make sure blade engagement
switch is in the down (OFF) position. Spread
control levers fully apart.
Refer to Figure 5-10 & Figure 5-11 on page 61:
2.
Begin on the left side by placing an oil pan (12" or
more in diameter with approximately 8 qt. capacity)
beneath the transaxle oil filter (#2).
3.
Remove screws (#3) and filter guard (#1).
4.
Clean transaxle exterior and expansion tank of any
debris. A degreaser may be needed.
5.
Unscrew the used oil filter (#2). Be sure to properly
dispose of filter.
6.
Remove expansion tank cap (#7) to facilitate
drainage.
7.
Allow oil to drain until it has slowed to a slow drip. Be
sure to properly dispose the oil.
8.
After oil has completely drained, install a new oil filter
per instructions below:
a. With a clean rag, clean the mounting surface that
the filter seats against.
b. Apply a thin coat of oil on the rubber seal surface
of the new filter (#2).
c. Screw filter on until it makes contact with the
surface it seats against.
d. Tighten filter an additional 3/4 to 1 full turn more.
e. Install filter guard (#1) with three 1/4" screws (#8).
Torque screws to 65 in-lbs.
IMPORTANT: The transaxles must be purged after
every oil change. See“Transaxle Purging
Procedures” on page 61.
IMPORTANT: Refer to Figure 5-10 & Figure 5-11 on
page 61. Clean debri from around the oil filter (#4),
top port plug (#9), and expansion tank cap (#12)
before draining any oil.
NOTE: Drain old oil filters of all free flowing oil prior
to disposal. Place used oil and oil filter in
appropriate containers and deliver to an approved
collection facility.
