How To Adjust Blade Spacing (Contact):

1) Raise and lock up the drill with the transport lock.

2) Remove the bolt (1) securing the opener disk on

one side.

Note: The bolt on the left side is a left-

handed bolt and the bolt on the right side is a stan-

dard right-hand threaded bolt.

3) Carefully remove the blade (2). Note how many

spacers (3) are outside the flange dust cover (4) and

inside the disk. Do not lose the hub components and

spacers.

4) To reduce the spacing between the disks, move

one spacer from the inside to the outside of the flange

dust cover. To increase the spacing, move one spacer

from the outside to the inside of the flange dust cover.

5) Reassemble and check disk contact.

Knock Down Tine Pitch Adjustment:

To avoid rapid wear, do not allow the knock down bars

or tines to contact the ground during operation.

1) Loosen the nuts (2)

2) Adjust the rear elevation of each knock down

assembly so it is as close as possible to level with the

opener frame.

3) After both sides are adjusted, tighten the nuts to

torque.

Knock Down Bar/Disk Gap Adjustment:

The gap should be about 0.01 inch.

1) Loosen the bolts (1).

2) Adjust the position of the tine (2) so the knock-

down bar (3) almost contacts the opener disk for the

full length of the bar.

3) Tighten the nuts to torque.

4) Rotate the opener disk a full turn or more to make

sure that contact is avoided.

Note: Adjust the scraper on the knock down tine so

that the gap is about 0.01 inch.
