Lister Adjustments
These instructions apply only to implements in Lister
configuration.
Typically the lister shovel adjustment is the first made,
followed by coulter height and hitch height. Furrower disc
adjustment may be made at any time.
Sharp Object Hazard:
Be cautious when working near the lister. The edges of the
furrower discs may be sharp.
Lister Shovel Adjustment
Refer to Figure 26 (furrower partially exploded)
Unless your circumstances dictate otherwise, Great
Plains recommends operating with the lister shovel
fully raised.
To adjust the shovel height:
1. Loosen the nuts on the lower shear bolts and the
lock nut on the top pivot bolt. Slide the mounting
bar up or down. Tighten the nuts to snug.
Note: If a lower shear bolt is ever failed by a field
obstruction, replace it with an identical:
802-720C HHCS 7/16-14X3 1/2 GR5 PLT
Do not use a higher grade bolt, or equipment
damage may result. Using a lower grade bolt may
result in nuisance shears. The front
7 ⁄
16
-14 bolt
may be moved to the rear position until a 802-720C
replacement bolt is obtained.
2. Tighten all three nuts to
7 ⁄
16
-14 Grade 5 torque
specification (50 foot-pounds, 67 N-m).
3. Re-check coulter height (page 29), and hitch height.
4. Set all rows identically, perhaps excepting rows in
tire tracks.
