ance, loosen jam nut (2) on opener-lift cylinders and turn
adjustment nut. See Figure 3-24. When openers are at
correct height, retighten jam nut. Repeat at each opener-
lift cylinder if necessary.

Toolbar Height
Toolbar height is factory set and normally will not require
adjustment. If you tear down the drill for repair or if the tool-
bar is visibly not level, spacer washers on vertical pivot
pins allow for a small amount of toolbar-height adjustment.
To check toolbar height, park drill on a level surface. Mea-
sure from ground to horizontal pivot pin. See Figure 3-26.
If dimension on either side of drill varies more than 1/4
inch, adjust toolbar height.
To adjust toolbar height, repositions spacer washers (1).
See Figure 3-26. First lower openers and set enough
opener down pressure to help balance frame. Raise tool-
bar by removing spacer washers from top of the vertical
pivot and placing them on bottom side of pivot. Lower tool-
bar by removing spacer washers from bottom of vertical
pivot and placing them on top of pivot.
