Refer to Figure 2
Initially adjust drill so bottom of opener tube
runs 26 inches above ground when drill is low-
ered in the field.
Refer to Figure 3
To adjust:
1. Make sure the top turnbuckle clevis is in
the lower mount hole.
2. Set turnbuckle length. Turn turnbuckle to
shorten or lengthen as necessary. Initially
set length to 17 1/2 inches between pin
centers to achieve the 26-inch dimension
mentioned above. When adjusting the
turnbuckle length, remember:
• Lengthening turnbuckle raises drill.
• Shortening turnbuckle lowers drill.
3. Level drill with top three-point link.
Refer to Figure 4
NOTE: When drill is level, parallel links will be
running slightly uphill towards the front.
The 1 inch dimension shown is a general di-
mension that will vary with planting conditions.
IMPORTANT: Make sure the opener mount
is running higher than the opener body.
This will ensure an ample reserve for open-
er upfloat in case the opener strikes a rock
or other object.
