Hydrostatic Drive System
!
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 or eyes, it must be
treated by a doctor familiar with this type of injury within a
few hours or gangrene may result. DO NOT DELAY.
!
WARNING
Always wear adequate eye protection when servicing the
hydraulic system.
The ZSR Series is equipped with Hydro-Gear ZT-3100
TM
Integrated Zero-Turn Transaxle units. The units are
located beneath the seat. See “Accessing Area
Beneath the Seat” on page 18 for instructions to pivot
the seat platform up. 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 50 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.
IMPORTANT: Repairs to a transaxle unit should be
performed by trained technicians only.
NOTE: Make certain to place the control arms in the
park position before rotating the seat platform up.
NOTE: The transaxle units are equipped with bypass
valves. For more information refer to “Moving Mower
with Stalled Engine” on page 18.

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 50 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 50 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 37:
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 37.
IMPORTANT: Refer to Figure 5-11 on page 37.
Clean debris from around expansion tank cap (#1),
top port plug (#4), and oil filter (#1) shown in
Figure 5-10 on page 37.
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.
