Tractor PTO Gearbox Lubrication

Checking Gearbox Oil Level

Check the gearbox oil level every 25 hours, and if necessary, add oil [SAE E.P. (Extreme Pressure) 80W-90 (API GL-5) gear lube] to maintain oil level to the FULL mark on the dipstick.

IMPORTANT: DO NOT overfill the PTO gearbox to avoid oil leakage out of the dipstick standpipe.

If the oil level is low, check the gearbox for any indi­ cation of an oil leak. If an oil leak is noted, the gear­ box will need to be removed and rebuilt.

Changing Gearbox Oil

The tractor PTO gearbox is oil filled. No scheduled oil change is required. However, changing the oil after­ the first 100 hour break-in period will extend gearbox life and is recommended.

1.Remove the drain plug in the bottom of the gearcase, drain the oil, and reinstall the plug.

2.Refill the gearbox through the dipstick stand­ pipe using 7 to 8 fl. oz. (21 to 24 cl) of SAE E.P. (Extreme Pressure) 80W-90 (API GL-5) gear lube. Remove­ plug in top of gearcase to vent air when refilling.

3.Check that the oil level is at the FULL mark on the dipstick. DO NOT overfill.

Gear Axle Lubrication

•The gear axle oil lubrication is SAE E.P. 80W-90 (API GL-5) gear lube.

•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 ax­le 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

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.
