Preparation and Setup
Coulter Adjustment
Coulter Height
38. Determine the desired depth of the shank and set the
gauge wheel in the appropriate hole.
39. Subtract 8” from the shank depth. Take this distance and
measure from the top of the frame (1) to the top of the
coulter shank (2). This will allow the coulter to run
approximately hub deep. If trying to deep rip less than 8”,
position the top of the coulter shank flush with the top of
the tube.
Coulter Alignment
40. Loosen the top and bottom set screws (3), jam nuts and
swivel limiter set screw (5). Lower the ripper in the
ground and drive forward a few feet.
41. Leave the ripper in the ground and tighten the top and
bottom set screws (3) and jam nuts (4). Position the swivel
limiter in the center of the slot and tighten the set screw
(5).
42. Check alignment of the coulter and shank. Move either
the coulter or shank so the shank is in the center of the
grove made by the coulter.
Note: If you want the coulter to swivel, loosen the top
and bottom set screws (1) and jam nuts (2). Retighten
jam nut to prevent from loosing set screw.
Coulter Spring
43. The coulter springs are preset at the factory to between
9

8
” to 10”. This is measured from the inside surface of
the coulter spring washer to the inside surface of the
coulter bushing.
Note: Adjusting the spring below 9

” could cause pre
