Level the Drill
Equal coulter depth across the drill can be maintained only
if the drill is level. The distance from the ground to the box
frame should be the same on both ends of the drill. Be cer-
tain all hydraulic systems have been bled before proceed-
ing.
1. Begin the leveling process by locating the threaded
eye bolt at the base of a gauge-wheel cylinder as
shown in Figure 2-1. The eye bolt is locked in place by
a jam nut on each side of a tube (1) welded to the cyl-
inder lug. Observe the amount of thread exposed
above the upper nut and below the lower nut. If the ex-
posed threads are roughly equal above and below the
jam nuts, no initial adjustment is needed. Go to step 3.

2. If the exposed threads above and below the jam nuts
are not equal, loosen and adjust until the exposed
threads are equal to within 3/8 in. Repeat for eye bolt
on other gauge-wheel cylinder
3. Move the drill to a level area. With the drill unfolded,
check that the tool-bar cylinders are completely ex-
tended. Raise the drill to its highest position with the
field-lift cylinders. Keeping the tractor at an idle,
rephase the cylinders by holding the remote lever on
for an additional 30 seconds. Immediately lower the
boxes until the coulters and openers are just ready to
touch the ground.
4. Move the gauge-wheel eye bolts in or out until the out-
er openers are the same height as the center openers.
NOTE: Eye-bolt adjustments are easier if the drill is first
lowered to the ground to remove some of the force on the
cylinders.
5. Repeat the steps until the drill is level end-to-end.
