19 Preparation and Setup
25 Series Openers Single Gauge Wheel
Refer to Figure 10
Initially adjust drill so bottom of opener tube runs
26 inches above ground when drill is lowered in
the field.
Refer to Figure 11
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 1/2 inches between pin centers
to achieve the 26-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 12
NOTE: When drill is level, parallel links will be
running level or 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.
