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.
IMPORTANT: Do not use a high pressure washer
on or around the hydraulic transaxles. Water
intrusion will result and void the warranty.
The Z Series are equipped with Hydro-Gear ZT-2800
& ZSR Series are equipped with Hydro-Gear ZT-3100
Integrated Zero-Turn Transaxle units. The units are
located beneath the seat. See "Accessing Area Beneath
the Seat" on page 19 for instructions to pivot the seat
platform up. These units are self contained and
maintenance free except for changing oil and filters.
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 more information refer to "Moving Mower
with Stalled Engine" on page 19.

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 51 for
hydraulic oil specifications.
