Leveling the 3S-4000HD/HDF Drill
To perform leveling, the drill must be hitched to a tractor,
with at least the hydraulics connected.
Negative Tongue Weight Hazard:
Be certain that drill is hitched securely to your tractor draw
bar and the safety chain is securely attached to tractor before
raising openers and unfolding drill. Raising openers on
unfolded, unhitched drill will cause drill tongue to rise
suddenly, which could cause serious injury or death.
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” on page 26 opener lift and

(nut and washers shown removed on one 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 87 and Figure 88
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.
5. Tighten the
7 ⁄
8
-9 inch box mount bolts to torque
specified in “Torque Values Chart” on page 104.

drill frame tube by at least
1 ⁄
2
inch (13 mm).
