Heights and Leveling
All frame sections must be at the correct height and level
to maintain even planting depth.
Periodic frame-leveling adjustments should not be nec-
essary. If you are having problems with uneven depth,
check air drill levelness and follow these procedures.
1. Complete “Bleeding Hydraulics” on page 112.
2. Unfold the air drill fully (page 25).
Set Tongue Height
Drill must be unfolded for this procedure.
Refer to Figure 13
Set the initial tongue height, tractor hitch, and changing
implement hitch configuration as necessary. Distance is
measured at top of tongue to ground level
If desired height cannot be attained with normal range of
hitch, hitch may be relocated in tongue bolt holes.
Always have two bolts in use, through two sets of hitch
holes and two sets of tongue holes.
