Frame Height
Drill operating height directly affects the working
range of the drill openers. Initially adjust frame
height as explained under “Leveling Drill”, page
17. You can make further adjustments to compen-
sate for field conditions.
Single Gauge Wheel
Refer to Figure 38
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 a 26-inch frame height for 25 se-
ries openers and 6 1/8 inches to achieve a 24-
inch frame height for 20 series openers.
When adjusting the linkage length, remem-
ber:
• Lengthening linkage raises drill.
• Shortening linkage lowers drill.
Level drill with top three-point link.
NOTE: Lowering the drill increases the risk of
opener damage on rocks or obstructions.
Dual Gauge Wheels
Refer to Figure 39
1. Loosen jam nut near top clevis of each
gauge-wheel turnbuckle.
NOTE: Jam nut is left-hand threaded.
2. Make sure upper clevis (2) is in upper mount
hole as shown.
3. Set turnbuckle length. Turn turnbuckle to
shorten or lengthen as necessary. Initially set
length to 17 1/2 inches between pin centers to
achieve a 24-inch dimension. When adjusting
the turnbuckle length, remember:
• Lengthening turnbuckle raises drill.
• Shortening turnbuckle lowers drill.
4. After adjusting both turnbuckles to the same
length, tighten jam nuts.
5. Level drill with top three-point link.
NOTE: Lowering the drill increases the risk of
opener damage on rocks or obstructions.
