2. Remove the reservoir cap and check the level
of the fluid. The reservoir has a fluid level COLD
mark and HOT mark. The reservoir oil level
should ALWAYS be at or above the COLD
mark and NEVER above the HOT mark.
Transmission Reservoir
and Air Bleed Plug Location
3. If the fluid is below the COLD mark (or the trans-
mission is not performing properly), loosen the
air bleed plug (located on the top of transmis-
sion case next to the plastic reservoir).
a. If a small amount of fluid leaks from around
the air bleed plug:
* The transmission is full of fluid.
* Tighten the plug and fill the reservoir to
the COLD level mark.
b. If no fluid leaks from around the air bleed
plug:
* Slowly add fluid into the reservoir until
fluid starts to leak from around the plug.
(Transmissions are serviced from the
factory with Mobil 1 (15W50) Synthetic
Oil. When it is necessary to add fluid,
refer to Specifications for the proper
fluid.)
* As soon as there is fluid leaking from
around the air bleed plug, tighten the
plug and fill the reservoir to the COLD
level mark. Wipe any excess oil off of
the transmission housing.
IMPORTANT: DO NOT overfill the transmission
reservoir. This will result in oil leaking out of the res-
ervoir cap vent when the transmission warms up. It
is preferable to add fluid to the transmission when it
is cold and make sure the oil is not above or be-
low the COLD level mark.
IMPORTANT: The transmission reservoir has a fine
mesh screen in the bottom to trap dirt and foreign
particles from entering the transmission. When fill-
ing the reservoir, fluid will flow quite slowly through
this screen; so it is essential that there is fluid at the
bleed plug before the transmission is considered
full.
IMPORTANT: Any attempt to remove or in any way
alter the filtering screen in the transmission reservoir
could cause damage to the transmission and will
VOID any transmission 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.
