Turning off the Accumulator (Gleaner R65/R66/R75/R76 and S Series)
The accumulator will affect the combine’s reaction time and greatly inhibit the auto header height
control’s 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.
