Height Setup: Model 605NT or 606NT
Set Tool Bar Height
Refer to Figure 11 and Figure 12
Tool bar height
is controlled by a depth stop
assembly on the left lift cylinder.
The suggested initial tool bar operating height is:
24
3 ⁄
4
in. (62.9 cm)
from the base of the opener tool bar to the ground, when
lowered in field conditions (opener discs in ground).
1. Use the tractor remote circuit to raise the drill to the
full extension of both lift cylinders. Hold the drill
raised for several seconds to re-phase the cylinders.
Remove any transport locks.
2. In field conditions, lower the drill to the desired tool
bar height. Pull forward to put openers in ground.
Set the remote to Neutral. Shut off the tractor.
3. Loosen the nut and bolt that secure the stop
weldment to the cylinder rod.
4. Slide the weldment up the rod until it contacts the
valve actuator
, then slide it up another
1 ⁄
8
in. (3 mm). Tighten the bolt.
5. Start the tractor. Raise and lower the drill. Pull
forward in ground. The lowering stops when the
weldment moves the actuator a short distance.
Shut off the tractor and verify the tool bar height.
Note: If further adjustment is required, the drill height
changes at approximately half the change in
weldment position. For example, raising the drill
another
1 ⁄
8
in. (3 mm) would require moving the
weldment up another
1 ⁄
4
in. (6 mm).
Level Model 605NT or 606NT
Refer to Figure 13
1.
Use hitch turnbuckle to level drill.
2. Lower unit to take weight off of drill. Do not adjust
with unit in raised position.
3. Loosen jam nuts on hitch turnbuckle.
4. Turn turnbuckle to shorten or lengthen until top of
drill frame is parallel to the ground being careful not
to extend clevises beyond turnbuckle.
5. Retighten jam nuts on turnbuckle.

Field Results Risk:
Prior to first use, check tool bar height
or the drill may run
too deep. Model 606NT drills may be shipped with the depth
stop valve actuator
set to maximum depth. The actuator
must be adjusted to desired opener height prior to first use.
