The roll timing gearbox, located inside the drive compartment at the right side of the self-propelled disc header,
transfers power from the gearbox-driven lower roll to the upper roll.
The gearbox (A) does not require routine maintenance or
service other than checking and changing the oil.

Checking and Changing Roll Timing Gearbox Oil

Change oil after the first 50 hours of operation. Perform subsequent oil changes every 100 hours or annually
(preferably before the start of the cutting season).

prior to checking.
