Closing Wheel Offset
The 1x12 wheels can be offset to help prevent trash from
plugging the closing wheels. If the closing wheels are not
offset, the wheels should be located in the front holes of
the press wheel arm.
To offset the wheels, do as follows:
1. Raise planter slightly to remove weight on the closing
wheels.
2. Remove the bolt holding the wheel, see
Figure 4-11.
3. Move the wheel to the rear hole and attach with the
bolt. Tighten the bolt to the correct torque value listed
in the Torque Values Chart for Common Bolt Sizes in
“Appendix” on page
63.
Closing Disk Adjustments
The closing disk options consists of two disks and a
6 1/2 x 12 press wheel. The disk down pressure can be ad-
justed to provide closing of the seed trench.
To select one of four down pressure settings, ratchet the
spring cam to the next cam height by turning the head of
the support bolt clockwise. Refer to Figure 4-12.
