2) LEVELING THE DRILL: Lower the drill as it is being driven forward.
A) On the 3P605NT level the drill box top with the tractors top 3-point link.
B) On the 605NT level the drill frame front to back with the turnbuckle on.
3) SPRING TENSION ON THE OPENERS: The "W" clips on the opener spring rods
should be in the lowest hole. This is the correct location in all conditions. The "W" clips
can be raised one hole in the wheel tracks only if penetration is not adequate.
4) SEED DEPTH: All of the opener "T" handles
should be set the same (about mid-range)
when starting. Check seed depth by digging
down to the seed, and adjust to desired depth
by moving the "T" handle. The openers in the
wheel tracks may need to be one hole deeper
because of soil compaction.
