Leveling the Drill
To perform leveling, the drill must be hitched to a tractor,
with at least the hydraulics connected.
Raising openers on unfolded, unhitched drill will cause drill
tongue to rise suddenly, which could cause serious injury or
death. Be certain that drill is hitched securely to your tractor
drawbar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
Center Box Frame Leveling
1. Park the drill on a clean level surface.
2. Raise the openers and lock them up. See “Raising
and Lowering Openers” in Operator’s Manual for
opener lift and lock instructions.
Refer to Figure 33
(bolts, nut and washers shown removed for clarity -
loosen, but do not remove them).
3.
Loosen the eight center box mount bolts, four bolts
on each side of tongue and slide center box frame
sideways until it is centered with mainframe and
transport axle.
Refer to Figure 34 and Figure 33
4.
Measure the height of center box opener frame
pivots
from the level surface and raise low end
of box frame up until both opener frame pivots
measure the same distance from the ground.

8
-9in box mount bolts to torque
specified in “Torque Values Chart” on page 39.
