INSTALLATION
ON JOHN DEERE 7000 COULTERS
1. Remove the 5/8 x 4” pivot bolt that attaches the unit coulter to the
bracket. Save the locknut for later use.
2. Loosely assemble the adjustment plate WA to the bracket/planter with ½”
x 2” bolt. Do not tighten this yet.
DANGER:
DO NOT USE SPACER STRAP ON COMBO ARM
W.A. AS A HANDLE, FINGERS MAY BE SERIOUSLY INJURED ON
SHARP EDGE OF BLADE, USE ½” SQ. DRIVE SOCKET TOOLS TO
ADJUST THIS PART.
3. Assemble the combo arm w.a. to the unit coulter with 5/8” x 9” bolt, 2-
9/32” spacer, 1-1/2” spacer and flat washer supplied. Use the 5/8”
locknut removed in step 1. Tighten this bolt securely. Tighten ½” x 2”
bolt.
4. Insert Combo Adjustment into appropriate hole to hold parts in position
and secure with hairpin cotter. *
5. Attach the spoke wheels to the ends of the combo arm.
NOTE: There are several different versions of the arm casting and bracket for the Deere unit
mounted coulter. There are slight variations between these parts that may require using
alternative combinations of parts (spacers) than out-lined in the above instructions. It may
also be necessary to use additional flat washers along with the spacers to achieve a
satisfactory fitment.
Do not be alarmed if the resulting fitment is not perfectly centered about the unit coulter
blade. It is acceptable for the wheels to be up to ½” off of centered perfectly.
* In some situations it may be preferable to replace the pin with a bolt
and nut for more secure attachment.
