Null4:
Heights and Leveling
All frame sections must be at the correct height and level
to maintain even planting depth. The hitch height sets
cart frame level, and must be at a consistent height to
both maintain level, and maintain radar speed calibra-
tion.
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.
Set Tongue Height
Drill must be unfolded for this procedure.
Refer to Figure 13
1.
Complete “Bleeding Hydraulics” on page 114.
2. Unfold the air drill fully (page 30).
3. Set the initial tongue height, tractor hitch, and chang-
ing implement hitch configuration as necessary. Dis-
tance is measured at bottom of hitch to ground level
4. 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.
Consistent Seeding Depth Risk:
Level frame in planting conditions. Failure to do so may result
in implement not producing desired results.
