Maintenance Instructions LUBRICATION

2.Check the oil level in the belt drive gearbox ev- ery 100 hours (or sooner if a visible oil leak has developed). With the deck in the normal oper- ating position, remove the level plug in the side of the gearcase. Add SAE E.P. (Extreme Pres- sure) 90W oil to maintain the oil level to the plug. If the oil level is low, check the gearbox for any indication of an oil leak. If an oil leak is not- ed, the gearbox will need to be removed and re- built.

3.Lubricate the dolly wheel pivot every 25 hours with general purpose grease.

4.Lubricate the U-Joint in the drive shaft every 8 hours with SAE general purpose lithium or molybdenum base grease.

Checking Gearbox Oil Level

Check the gearbox oil level every 25 hours, and if necessary, add oil [SAE E.P. (Extreme Pressure) 90W 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 and vented. No scheduled oil change is required. However, chang- ing 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) 90W gear lube.

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 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 ax- le and fill until oil is at the level plug.

∙Change axle oil every 1000 hours or two (2) years.
