LUBRICATION<br />
2. Check the oil level in the belt drive gearbox every<br />
100 hours (or sooner if a visible oil leak has<br />
developed). With the deck in the normal operating<br />
position, remove the level plug in the side<br />
of the gearcase. Add SAE E.P. (Extreme Pressure)<br />
90W oil to maintain the oil level to the<br />
plug. If the oil level is low, check the gearbox for<br />
any indication of an oil leak. If an oil leak is noted,<br />
the gearbox will need to be removed and rebuilt.<br />
3. Lubricate the dolly wheel pivot every 25 hours<br />
with general purpose grease.<br />
4. Lubricate the U-Joint in the drive shaft every<br />
8 hours with SAE general purpose lithium or<br />
molybdenum base grease.<br />

Check the gearbox oil level every 25 hours, and if<br />
necessary, add oil [SAE E.P. (Extreme Pressure)<br />
90W gear lube] to maintain oil level to the FULL<br />
mark on the dipstick.<br />
IMPORTANT: DO NOT overfill the PTO gearbox to<br />
avoid oil leakage out of the dipstick standpipe.<br />
If the oil level is low, check the gearbox for any indication<br />
of an oil leak. If an oil leak is noted, the gearbox<br />
will need to be removed and rebuilt.<br />
Dipstick Location, Tractor PTO Gearbox<br />
Changing Gearbox Oil<br />
The tractor PTO gearbox is oil filled and vented. No<br />
scheduled oil change is required. However, changing<br />
the oil after the first 100 hour break-in period<br />
will extend gearbox life and is recommended.<br />
1. Remove the drain plug in the bottom of the<br />
gearcase, drain the oil, and reinstall the plug.<br />
2. Refill the gearbox through the dipstick standpipe<br />
using 7 to 8 fl. oz. (21 to 24 cl) of SAE E.P.<br />
(Extreme Pressure) 90W gear lube.<br />
3. Check that the oil level is at the FULL mark on<br />
the dipstick. DO NOT overfill.<br />
Gear Axle Lubrication<br />
• The gear axle oil lubrication is SAE 80W-90 (API<br />
GL-5) gear lube.<br />
• Check the axle oil level after every 100 hours of<br />
operation by removing the oil level plug. If additional<br />
oil is needed, remove the breather vent on top of axle<br />
and fill until oil is at the level plug.<br />
• Change axle oil every 1000 hours or two (2)<br />
years.<br />
