Gear Axle Lubrication
•The gear axle oil lubrication is SAE
•Check the axle oil level after every 100 hours of operation by removing the oil level plug. If additional oil is needed, remove the breather vent on top of ax- le and fill until oil is at the level plug.
•Change axle oil every 1000 hours or two (2) years.
Hydrostatic Transmission Fluid
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 engine 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 contaminants entering the transmission will accelerate wear and eventually cause loss of power to the drive wheels.
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.
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 DTE 18M hydraulic oil. When it is necessary to add fluid, refer to Specifications for the proper flu- id. Use any of the fluids listed.)
*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 reservoir 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 below 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 filling 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.
