Gear Axle Lubrication - Model MS, MC, MD, MT
• The gear axle oil lubrication is SAE 80W-90 (API
GL-5) gear lube.
• Check the axle oil level after every 100 hours of op-
eration by removing the oil level plug. If additional oil is
needed, remove the breather vent on top of axle and fill
until oil is at the level plug.
• Change axle oil every 1000 hours or two (2) years.
Hydrostatic Transmission Fluid - Model MS, MC,
MD, MT
Checking Hydrostatic Transmission Fluid Level
Hydrostatic transmission fluid level should be checked
every 25 hours of machine operation. It is preferable
to check the fluid level when fluid is cold. Check
fluid level as follows:
1. Park the mower on a level surface. Stop the en-
gine and wipe dirt and contaminants from around
the reservoir cap and air bleed plug.
IMPORTANT: Before removing the reservoir cap,
clean any dirt from around it. Any dirt or contami-
nants entering the transmission will accelerate
wear and eventually cause loss of power to the
drive wheels.
IMPORTANT: Removing or breaking the seal with-
in the first 500 hours will void the warranty.
NOTE: Check oil level of sealed hydrostatic trans-
mission after first 500 hours using a light next to
the reservoir.
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.
