OPERATION AND FIELD SETTINGS

Tillage Shank Assembly Depth

The mole shank assembly shatters the root zone
compacted layer while placing fertilizer at two precision
depths, if desired. Once the compacted layer depth and
thickness is researched and established, the tillage
shank assembly depth is adjusted accordingly.
Varying compacted layer depth and thickness, either
within or between fields, will warrant tillage shank depth
adjustment. The tillage shank point should operate in
close proximity to the lowest point of the compacted
layer. Operating the tillage shank point below the
compacted layer will heave and lift the compacted layer.
It is recommended to operate the tillage shank point near,
but not past, the lowest point of the compacted layer for
optimum performance.
NOTE: Depth adjustment of the Mole Shank/Dry Mole
Shank and wavy coulters should always be done
in conjunction with each other.
Toolbar height and orientation must be established prior
to adjusting tillage shank depth. See "Toolbar Height and
Orientation" on page 5-2.

DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Make sure all personnel
are clear of the implement before lowering.
DANGER
!
Avoid crushing. An uneven surface could cause the
implement to shift or fall, resulting in injury or death as
well as implement damage. Park the implement on a
clean, dry, level surface.
DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Use bar stands and
cylinder stops to support the implement.
1. Lower the implement to the ground, place the tractor
in park, turn off the engine, and remove the key.
2. Remove buildup of grease, oil, and debris prior to
adjusting tillage shank assembly depth. See
"Implement Inspection" on page 7-4.
CAUTION
!
Be extremely careful working around unshielded sharp
edges. Injury may result from contact with sharp edges.
3. Support tillage shank assembly (1).
4. Loosen jam nuts (3) and set bolts (2).
5. Remove hairpin (4) and depth adjustment pin (5).
6. Adjust tillage shank assembly to desired depth
setting (6). For depth settings, see "Tillage Shank
Depth Adjustment Chart" on page 5-12.
7. Install depth adjustment pin and hairpin.
8. Tighten jam nuts and set bolts to specification. See
"Torque Specifications" on page 7-2.
NOTE: Jam nuts and set bolts can be moved to the
opposite side for ease of adjustment. Be sure to
remove plug bolts to protect threads.
