20 Series Opener Dual Gauge Wheels
Refer to Figure 7
Initially adjust drill so bottom of opener tube runs
24 inches above ground when drill is lowered in
the field.
Refer to Figure 8
To adjust:
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 the 24-inch dimension mentioned
above. 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.
Refer to Figure 9
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.
IMPORTANT: 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.
