Frame Level
The 00 and 00HD Series openers are designed to
produce optimal results when the opener frames are
level with the ground. Operating with drill frame level is
also recommended, and this is set by hitch height (page
18).
If planting depth is not as desired on just one or two drill
sections, first check the setup items for “
” on page 74. Then check and adjust the following
items:
•
opener sub-frame adjustment: all gauge wheel
trunnions in same frame pivot holes - see
“
•
opener pivot height: all openers pivoting in same
hole at their mounts (possibly excepting rows in tire
tracks) - see page 55,
•
opener press wheel height: all row units set the
same - see page 58, and;
•
opener spring down-force: all row units set the same
(possibly excepting rows in tire tracks) - see page 55.
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.
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.
