Lubrication Service Schedule
IMPORTANT: Your grain cart has grease ttings at all critical points. These should be serviced before the grain cart is put into operation.
WARNING
BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE GRAIN CART
PTO & DRIVELINE: The grease ttings on the PTO should be serviced after every 8 hours of use. Service the grease ttings on each of
the drive bearings and also the universal joint after every 8 hours of use.
AUGER FOLDING MECHANISM: One grease tting is located on the pivot pin of the folding auger. This tting should be serviced after
every 8 hours of use. Service the grease tting on the hanger bushing assembly (top end of the lower auger assembly) after every 8
hours of use or as needed.
SPRING LOADED UPPER AUGER BEARING: Service the grease tting on the upper auger bearing (located at the top end of the upper
auger assembly) after every 8 hours of use. Lubricate the springs and retaining bolts on the bearing before prolonged storage of the
grain cart.
GEARBOX: Gearbox lubricant has been added to the gearbox during nal assembly. Recheck the lubricant level before initial operation
of the grain cart, then periodically according to use. An inspection plug is located in the center of the top of the gearbox mount plate.
To check the uid level, remove the vented inspection plug and drain plug at the bottom of the gearbox. Drain the lubricant. Return
the drain plug and rell the gearbox with 24 ounces (0,71 liters) of gearbox lubricant. DO NOT OVERFILL. Use SAE 80W-90 gearbox
