Maintenance Instructions LUBRICATION60Gearbox, Dolly Wheel, and U-Joint LubricationTractor PTO Gearbox LubricationChecking Gearbox Oil LevelCheck the gearbox oil level every 25 hours, and ifnecessary, add oil [SAE E.P. (Extreme Pressure)80W-90 (API GL-5) gear lube] to maintain oil level tothe FULL mark on the dipstick.IMPORTANT: DO NOT overfill the PTO gearbox toavoid 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.Dipstick Location, Tractor PTO GearboxChanging Gearbox OilThe tractor PTO gearbox is oil filled. No scheduledoil change is required. However, changing the oil af-ter the first 100 hour break-in period will extendgearbox life and is recommended.1. Remove the drain plug in the bottom of thegearcase, 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) gearlube. Remove plug in top of gearcase to vent airwhen refilling.3. Check that the oil level is at the FULL mark onthe dipstick. DO NOT overfill.Gear Axle Lubrication• The gear axle oil lubrication is SAE 80W-90 (APIGL-5) gear lube.• Check the axle oil level after every 100 hours ofoperation by removing the oil level plug. If additionaloil 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 FluidChecking Hydrostatic Transmission Fluid LevelHydrostatic transmission fluid level should bechecked every 25 hours of machine operation. It ispreferable to check the fluid level when fluid iscold. Check fluid level as follows:1. Park the mower on a level surface. Stop theengine and wipe dirt and contaminants fromaround the reservoir cap and air bleed plug.IMPORTANT: Before removing the reservoircap, clean any dirt from around it. Any dirt orcontaminants entering the transmission will ac-celerate wear and eventually cause loss of pow-er to the drive wheels.IMPORTANT: Removing or breaking the sealwithin the first 500 hours will void the warranty.NOTE: Check oil level of sealed hydrostatictransmission after first 500 hours using a lightnext to the reservoir.Dolly WheelPivotU-JointBelt DriveGearboxPTOGearboxVent PlugDipstickJackshaft
