Leveling The Drill 606NT:
1) The drill must be lowered until weight is taken off of the
hitch turnbuckle. Do not attempt to adjust the turnbuckle with
the drill risen.
2) Loosen the jam nuts on the hitch turnbuckle (1).
3) Shorten or lengthen the turnbuckle until the top of the drill
frame is parallel to the ground.
the clevises beyond the turnbuckle.
4) Once the drill is level, re-tighten the jam nuts.
Adjusting 3-Point Height 3P606NT:
Raising the gauge wheel spindle provides deeper coulter
depth while lowering the gauge wheel provides shallower
depth.
Note: Do not lower the coulters to aid in penetrating
hard soil. Instead, increase coulter down-force or add optional
weight to the drill.
1) Determine the desired coulter depth. With new coulter
blades, the axle holes provide the following depths:

2) Raise the drill until the spindle can be adjusted any distance.
3) Loosen the chain idlers.
4) Remove the wheel bolts and move the spindle to the desired
hole. Re-install the wheel bolts.
5) Re-engage the chain idlers and check the overall depth.
Individual Coulter Height Adjustment:
Individual coulter depth may be adjusted by raising and lower
the spring bar.
1) Determine the new desired coulter depth, and/or the differ-
ence between that and the current depth.
2) Raise the drill until the coulters are just touching the ground.
The press wheels are supporting some weight at this point.
3) Measure the current spring bar length, from the bottom of
the tool bar to the bottom of the spring bar. For reference, the
factory setting is roughly 12 1/2 inches (31.8 mm).
Note: Be careful not to extend
