Leveling: Offset-Single Wheel
The offset-single gauge wheel adjusts for bedding by
changing the turnbuckle length.
Refer to Figure 10
1.
Check the link length. The factory setting for link
length
, measured at centerlines, is:
17 1 ⁄
2
in (44.5cm)
This corresponds to an opener tool bar height of:
26in (66cm)
This is for non-bedded planting.
To adjust the drill for bedded planting:
2. Hitch it to a suitable tractor. Move it to representative
bedded ground, with the wheels between beds.
3. Lower the drill to planting position and set the 3-point
hitch circuit to Float.
Refer to Figure 11
Note: This presumes a planting depth of 1.75in (44mm).
If your depth is different, re-adjust the tool bar
height when adjusting the press-wheels (page 48).
4. Adjust drill distance between bottom of opener tool
bar and planting ground (bed tops):
Refer to Figure 10
5.
To adjust turnbuckle length, loosen jam nut . Turn
turnbuckle to shorten or lengthen as necessary.
When adjusting the turnbuckle length, remember:
+ Lengthening turnbuckle raises drill.
- Shortening turnbuckle lowers drill.
Re-tighten jam nut when height is final.
Note: Do not expose more than 3in (7.6cm) of thread at
either end of turnbuckle.
6. Level drill with top three-point link.
Refer to Figure 12
7.
Level drill with top of three-point link. Adjust so that
row units are inclined slightly uphill, measured
at
the ends of the parallel arms:
The 1in/2.5cm dimension shown is a general dimension
that varies with planting conditions.
Ensure the opener mount is running higher than the opener
body. This ensures ample reserve for opener upfloat if the
opener strikes a rock or other object.
Tool bar height 26in (66cm)
Arm inclination 1in (2.5cm) maximum
