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
