Checking Air Drill Height
The air drill is designed to operate with all sections of the
main tool bar nominally 76.2cm (30in) above the planting
surface. The height of the center section is not routinely
adjustable. Set planting depth with row unit adjustments.
When lowering the air drill for the first time on the plant-
ing ground:
1. Completely lower the main tool bar. If necessary, first
lift off transport locks, remove and stow locks.
2. Set hitch to planting height.
3. Pull forward a meter or so (a few feet).
Drill must be fully lowered to field position (with openers into
ground) and hitch height must be set before making side-to-
side adjustments.
Refer to Figure 14

Check tool bar height across air drill. See page 128
for further detail and adjustment.
