Barring-Off Adjustments
These instructions apply only to implements in Cultivator
configuration, and equipped with the optional 591-034A
Barring-Off accessory.
Typically these adjustments are made after setting
cultivator depth, coulter height and hitch height.
Sharp Object Hazard:
Be cautious when working near the barring-off discs.
The edges may be sharp.
Barring-Off Width
Refer to Figure 24 (depicting unequal extensions for clarity)
Sliding tubes and bent pins provide a choice of widths
(measured at the disc bottom edges), ranging from:
11.3 inches (28.7 cm) minimum, to
31.3 inches (79.5 cm) maximum
By alternating tube and sleeve holes, total width may be
adjusted in increments of:
5 ⁄
8
inches (16 mm).
To adjust:
1. Raise the implement slightly.
2. Remove the hairpin cotter and each bent pin .
3. Slide the disc mounting tubes in or out.
4. Re-secure with bent pin and cotter.
Equipment Damage Risks:
Always have at least two of the holes of the disc mounting
tube
inside the attachment mounting tube , or tube
damage may result.
Refer to Figure 25
Note: If a cap
is present, do not mount a barring-off
tube in that receiver tube. Leave the cap in place.
These caps are found at the inside end of the front
receiver tube of the inside wing row unit. In current
row spacings, a barring-off disc installed in this
tube would strike other implement parts during fold.
Barring-Off Disc Height
Refer to Figure 24
To adjust the disc height, loosen the nuts
at the clamp.
Slide the mounting bar up or down. Re-secure the
nuts.
Set both disc heights the same on each row. The bar top
must be flush with or above the top of the clamps.
