Coulter Adjustment

Adjusting the coulter depth is accomplished by re-mounting the coulter blade in one of the six

mounting holes arranged in a staggered pattern in the coulter bracket.

Figure 64

Raise unit and lower service stands before

working on coulters. Do not attempt to move

blade when the current or new position causes

it to contact the ground during the adjustment.

Be careful around the front end of row units.

Row cleaner tines and coulter blades may be

sharp.

To adjust coulter depth:

1. Determine the present opener and coulter

depths.

2. Note which bracket hole the coulter is

presently using.

3. Determine which new hole will position the

coulter closer to the 1/4in-above depth. See

the table below.

4. Remove the 5/8-11 x 4in bolt, lock washer

and nut ( A in Figure 64).

5. Move the blade to the new position. Insert

the bolt, and tighten on the lock washer and

nut.

6. Re-adjust row cleaners, if installed. If a

worn coulter cannot be adjusted to

satisfactory operating depth, replace coulter.
