Adjusting Header Draper Speed - MacDon FlexDraper FD1 Series Operator's Manual

Adjusting Header Draper Speed

The side drapers carry the cut crop to the float module feed draper, which then feeds it into the combine. The speed
is adjustable to suit crops and crop conditions.
The side drapers (A) are driven by hydraulic motors and a
pump that is powered by the combine feeder house drive
through a gearbox on the float module. Side draper speed is
adjustable with the flow control valve on the float module,
which regulates the flow to the draper hydraulic motors.
Draper speed is also adjustable with an optional control in
the cab. See below.
To access the flow control valve, pull bottom of
compartment cover (A) to open.
The flow control valve (A) has settings from 0–9 on the
barrel to indicate the draper speed. The flow control valve is
factory-set to 6, which should be sufficient for normal crop
feeding.
To change the draper speed, shut down the combine and
rotate the flow control valve dial to adjust the control.
