minimum distance of 20 feet.
It must be cut straight.
•
Stop the harvester.
The harvester will be parallel to the cut edge, the steering
wheels ‘straight ahead’, and the cutter head ‘down’.
Switch the Auto-Steer ‘ON’. Turn the Tractor ‘OFF’.

IMPORTANT
Before operating the Auto-Steer
remove the ¼ inch Bolt from
the Cam

corrosion forming on the Roller Shaft, causing it to ‘stick’ and
adversely affecting the operation of the Auto-Steer
Position the Sensor Valve End Plate Cover, complete with the
rubber seal, re-fit the 40mm Lg. Socket Head Screws.
