AUTO-STEER
Fine Adjust Control.
Cable Arm Adjustment.
When the Fine Adjust Control has been set at its mid-
point of travel, the Cable Arm must be correctly set-up:
• Remove the Clevis End ‘A’, from the Cable Pivot
Arm ‘B’.
• Rotate the Pivot Arm so that the Pivots ‘C’, are
perpendicular to the Support Frame ‘D’.
• Adjust the Clevis End ‘A’, to align with the hole in
the Pivot Arm. Fit the Clevis Pin and Cotter Pin,
and tighten the Clevis End Lock-nut.
Guide Shoe Adjustment.
The Guide Shoe Adjuster ‘E’, determines where the Guide
Shoe will ‘drop’ on the ground, when the Auto-Steer is
activated.
For most harvesting conditions it is set to position the Shoe
1 to 2 inches away from the ‘cut edge’.
If adjustment is required :
• To move the Guide Shoe ‘away’ from the cut edge,
loosen the Locknut and Bolt ‘F’, and slide the Adjuster
Tube ‘IN’.
• To move the Guide Shoe ‘closer’ to the ‘cut edge’,
Slide the Adjuster Tube ‘OUT’.
After adjustment, tighten the Bolt and Locknut.
Tracking Adjustment.
The recommended method of setting the Tracking is :
• Position the harvester ‘ready to cut’.
• With the Auto-Steer ‘OFF’, cut a strip of turf, for a
minimum distance of 20 feet. It must be cut straight.
The harvester will be parallel to the cut edge, the steering
wheels ‘straight ahead’, and the Cutter Head ‘down’.
• Engage the Auto-Steer, the Guide Shoe will ‘drop’.
• Set the Fine Adjust Control to its Mid-Point as shown
on page 5-3.
• Position the Guide Shoe against the ‘cut-edge’ of
the turf.
• Fit a wrench on the Lever Arm ‘G’.
• With the wrench, turn the Lever Arm to rotate the
Cam until the ¼ inch hole in the Cam ‘H’, lines up
with the hole in the support plate.
• Insert a ¼ inch bolt in the holes to lock the Cam in
place.
The Sensor Valve will now be in the ‘NEUTRAL’ position.
To prevent the Lever Arm from rotating, use the wrench to
hold firmly it against spring pressure and proceed to :
• Loosen the Shoe Arm Clamp Bolt (see ‘C’, page 5-3),
and move the Guide Shoe until it is firmly against the
‘cut edge’.
• Tighten the Clamp Bolt.
IMPORTANT
Before operating the Auto-Steer the ¼ inch bolt must be
removed from the Cam. Failure to do so will result in
damage to the Auto-Steer mechanism
