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, espe-
cially 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 adjust-
ments to this attachment.
