Frame Level
Refer to Figure 55
The 00HD Series openers are designed to produce opti-
mal results when the opener frames are level with the
ground. Operating with drill frame level is also recom-
mended, and this is set by hitch height (page 15).
If planting depth is not as desired on just one or two drill
sections, first check the setup items for “Leveling the
Drill” on page 84. Then check and adjust the following
items:
• opener sub-frame adjustment: all gauge wheel trun-
nions in same frame pivot holes - see “Opener-Sub-
frame Adjustment” on page 64,
• opener pivot height: all openers pivoting in same hole
at their mounts (possibly excepting rows in tire tracks)
- see page 66,
• opener press wheel height: all row units set the same -
see page 69, and;
• opener spring down-force: all row units set the same
(possibly excepting rows in tire tracks) - see page 66.
Refer to Figure 56
This photograph illustrates openers too high in front.
Increase hydraulic pressure and/or lengthen opener
springs.
Check sub-frame pivot in use at higher pressures.
Refer to Figure 57
This photograph illustrates openers too low in front, also
known as “bulldozing”. Decrease hydraulic pressure
and/or shorten opener springs.
Check sub-frame pivot if pressures have recently been
reduced.
