Setting Up & Adjustment
Height Adjustment
To achieve major adjustment to height of cut; reposition the two side plates attached
to the rear roller. A finer adjustment to cut can be achieved by lengthening or
shortening the top link of the tractor (Fig. 3).
Mechanical Offset
The linkage ‘A’ frame (Fig. 4) can be slid along the tube to obtain numerous settings
from central to fully offset by simply slackening the clamping bolts, position the ‘A’
frame and re-tighten the bolts. Remember to regularly check that these bolts are
tight.
Hydraulic Offset – Optional
Can be moved from central to fully offset by operating the tractor external spool valve
to the desired position. Lubricate the sliding tubes with grease/oil to prolong the life of
the bushes.
To reduce the strain on the drive line ensure to operate the PTO in a straight line.
