ASSEMBLY INSTRUCTIONS
STEP 8. Insert the locking collar into the pivot casting of the coulter assembly. Slide the shorter offset end of the
shank down through the assembly and drive the 3/8" x 2 ½" roll pin through the bottom hole of the shank for a
retainer.
NOTE: For additional clearance for and aft of the coulter blades, assemble half of the coulters with the lower portion
of the offset shank forward (to be mounted on the front of the toolbar) and assemble the remaining coulters with the
offset shank backward (to be mounted on the rear of the toolbar).
STEP 9. Screw the 5/8" x 1" square head set screw into the locking collar; triple tighten (tighten, loosen, tighten,
loosen, tighten) to 100 ft. lbs. max. torque. The locking collar should carry the weight of the coulter instead of the roll
pin.
Note: Do not allow the roll pin to set into the notch of the pivot casting since that will lock the coulter from swiveling.
