1. For maximum tilling depth and transport lift height
locate link of lift chain in the lowest notch of lift lever
(Fig. 22). This position will have the greatest lift effort.
2. For minimum tilling depth and reduced lift height,
locate the link of lift chain in the upper clevis notch of
lift lever (Fig. 22). This position will have lowest lift
effort.
3. For variations of less than the three notches in the lift
lever, disconnect the lift cable from the lift arm and
rotate the trunnion (Fig. 22) Turning clockwise
increases lift height and reduces tilling depth and
counter clockwise reduces lift height and increases
tilling depth.
