Hydrostatic Transmission Fluid
Checking Hydrostatic Transmission Fluid Level
The hydrostatic transmissions are sealed units
and do not need to be opened to check the uid
level. Hydrostatic uid level should be checked ev-
ery 25 hours of machine operation. It is preferable
to check the uid when the uid is cold. Check
uid levels as follows:
IMPORTANT: Removing or breaking the seal on
the hydrostatic reservoir cap within the rst
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 uid level COLD mark. The
reservoir oil level should ALWAYS be at or
slightly above the COLD mark.
4. If the uid is below the COLD mark (or the trans-
mission is not performing properly) contact
your local dealer. Attempting to add uid or
service the transmission may VOID THE
TRANSMISSION WARRANTY.
Grease Fitting and Oil Point Lubrication
Lubricate the grease ttings 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 ttings 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 discon-
nect tube assembly for easy access to grease t-
tings.
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.
