Hydrostatic Transmission Fluid
Checking Hydrostatic Transmission Fluid Level
The hydrostatic transmissions are sealed units
and do not need to be opened to check the fluid
level. Hydrostatic fluid level should be checked ev-
ery 25 hours of machine operation. It is preferable
to check the fluid when the fluid is cold. Check
fluid levels as follows:
IMPORTANT: Removing or breaking the seal on
the hydrostatic reservoir cap within the first
1000 hours will VOID THE TRANSMISSION WAR-
RANTY.
1. Park the mower on a level surface. Stop the
engine and wipe dirt and contaminants from
around the base of the reservoir to better see
the COLD mark.
2. The level of the oil can be seen through the side
of the opaque reservoir (DO NOT REMOVE
RESERVOIR CAP); using a light next to the
reservoir will help make the level more visible.

3. The reservoir has a fluid level COLD mark. The
reservoir oil level should ALWAYS be at or
slightly above the COLD mark.
4. If the fluid is below the COLD mark (or the trans-
mission is not performing properly, contact your
local dealer. Attempting to add fluid or ser-
vice the transmission may VOID THE TRANS-
MISSION WARRANTY.
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after ev-
ery 25 hours of operation. Lubricate more often
when operating in dusty or dirty conditions. Use
SAE general purpose lithium or molybdenum base
grease for grease fittings and light machine oil (SAE
10) to lubricate oil points. Lubricate the locations
shown in the Chassis and Deck Lubrication
Points illustration.
NOTE: PTO universal joints (on the deck and trac-
tor) require routine lubrication after every 8 hours of
running time. Remove tractor PTO quick disconnect
tube assembly for easy access to grease fittings.
NOTE: The best way to lubricate the PTO tube half
of the universal joint assembly is to remove it from
the tractor. See instructions for removing and install-
ing PTO quick coupler, refer to Deck Installation in
Mower Deck Installation on Tractor in the Assem-
bly Instructions.
