Refer to Figure 34
7. In order to raise or lower the chopper reel assembly, adjust the
eyebolt by loosening the jam nuts . Extend eyebolt to lower
the assembly, retract eyebolt to raise assembly.
8. Tighten jam nuts securely.
9. To adjust the chopper reels fore and aft, remove bolt and slide
tubes in or out. Adjustment is 3” for each hole. The bolt may
need to move from the back hole to the front hole or vice verse,
depending on the amount of adjustment needed. Because of
weight concerns, the choppers should run as far forward as
possible while still allowing soil and residue to flow freely from
the rear shanks.
Refer to Figure 35
10. The down pressure can be adjusted two ways. For slight down
pressure, loosen set screw from collar and slide collar up
for more pressure. Tighten set screw to secure.
11. For added down pressure, tighten lock nut on top of spring.
This will compress the bottom of the spring, increasing down
pressure. This will also raise the chopper reel so you will also
need to re-adjust eyebolt at the bottom of the spring bolt
accordingly.
Buster Bar
Refer to Figure 36
12. The buster bar attachment is designed to knock the tops of the
ridges and to help fill the valleys behind the chisel shanks. The
down pressure can be set by the 1/2” bolt under the arm. To
adjust the pressure, loosen the jam nut on the back side and then
adjust the 1/2” bolt. To increase down pressure, loosen the bolt.
In some instances, especially when you are running the chisel
very deep, the bolt head will not be in contact with the ball joint
when the unit is out of the ground. Once the unit is lowered into
the ground, the bolt head will come in contact with the ball joint
and pressure will be applied. Once the proper tension is set,
retighten the jam nut. There are no other adjustments to this
attachment.
