Turning the Accumulator Off (Gleaner R65/R75)
The accumulator will affect the combine’s reaction time and greatly inhibit the Auto Header Height performance.
Refer to the combine operator’s manual for proper
procedure when turning accumulator off and on. For best
performance, turn the feeder house accumulator off.
NOTE:
The accumulator is located in front of the front
left axle beam.
