17 Preparation and Setup
Leveling the Drill
20 Series Opener Single Gauge Wheel
Refer to Figure 4
Initially adjust drill so bottom of opener tube runs
24 inches above ground when drill is lowered in
the field.
Refer to Figure 5
To adjust:
1. Make sure block mount of the spring linkage
(2) is in the lower mount hole for planting in
bedded irrigation. The upper hole is for non-
bedded ground.
2. Set spring linkage length. Turn spring linkage
to shorten or lengthen as necessary. Initially
set length to 6 1/8 inches between pin centers
to achieve the 24-inch dimension mentioned
above. When adjusting the linkage length, re-
member:
• Lengthening linkage raises drill.
• Shortening linkage lowers drill.
3. Level drill with top three-point link.
Refer to Figure 6
NOTE: When drill is level, parallel links will be
running slightly uphill towards the front.
The 1-inch dimension shown is a general dimen-
sion that will vary with planting conditions.
Make sure the opener mount is running higher than
the opener body. This will ensure an ample reserve
for opener upfloat in case the opener strikes a rock or
other object.
