Gauge Wheel Adjustments
Refer to Figure 63 and Figure 64
Gauge wheel adjustment can most easily be
accomplished with the planter in the raised position.
The 1-5/8 inch deep wall socket is mounted near
the left-hand drive wheel. It is used to loosen the lock
nut and turn the adjustment nut weldment for
gauge wheel adjustments.
The gauge wheel yoke assembly is a spring-loaded
link with no spring rate adjustment. Spring tension is
fixed. The yoke assembly allows approximately
5/8 inch of spring travel.
1. Use the provided 1-5/8 inch deep wall socket.
Loosen the lock nut
on the adjustment spool .
Do not turn the adjustment nut weldment . Turn the
lock nut no more than 1/2 turn.
2. Align the flats of the lock nut with the adjustment
nut weldment. Slide the 1-5/8 inch deep wall socket
over the lock nut and the adjustment nut weldment.
Turn the center adjustment spool counter-clockwise
(CCW) to lower the gauge wheel.
Turn the center adjustment spool clockwise (CW) to
raise the gauge wheel.
3. Lower the planter so that the bottom of the frame is
26 inches (66 cm) from the ground or bed level.
4. Tighten the lock nut to secure the gauge wheel
setting.
Lower the planter to confirm a 26-inch frame height with
the gauge wheel spring compressed.
Adjusting Ground Drive
For information on setting the ground drive refer to the
seed rate manual. See “
for the part number of the Seed Rate Manual.
Planting on Beds (All Models)

has two anchor hole positions:
The lower anchor hole is typically used for planting
on bedded ground.
The upper hole is typically used for non-bedded (flat
ground) planting.
