Coulter Scraper Adjustment:

This adjustment needs to be made as scrapers wear or

when the scrapers are replaced. At each row, check the

gaps (8) between the lower edges of the scrapers and

the coulter depth band. The factory setting is 3/32" (0.9

inch, 2.4 mm).

To adjust the scraper:

1) Loosen the nuts (9) at the slots.

2) Slide the scraper down until the correct gap is

achieved. Keep the scraper centered on the coulter

blade and tighten the nuts.

Note: If the scraper reaches the end of its slots, and the

gap (8) is larger than 3/32" (2.4 mm), the scraper is worn

out and must be replaced.

Barring-Off Adjustments (Option):

Sliding tubes and bent pins provide a choice of widths

(measured at the disc bottom edges), ranging from 11.3"

(28.7 cm) to 31.3" (79.5 cm). By alternating tube and

sleeve holes, the total width may be adjusted in incre-

ments of 5/8" (16 mm).

To adjust:

1) Raise the implement slightly.

2) Remove the hairpin (10) and each bent pin (11).

3) Slide the disc mounting tubes in or out depending on

the desired width.

4) Secure the disc mount with the bent pin and hairpin.

Note: If a cap is present, do not mount a barring-off tube

in that receiver. In that current row spacing, a barring-off

disc installed in this tube would strike other implement

parts during fold.

Lister Shovel Adjustments:

Great Plains recommends operating with the lister

shovel fully raised unless conditions dictate otherwise.

To adjust the shovel height:

1) Loosen the nuts (12) on the lower shear bolts and the

lock nut (13) on the top pivot bolt.

2) Slide the mounting bar (14) up or down and re-tighten

the nuts.
