Weights
If more weight is required for coulters to penetrate the soil,
weight bracket kits are available from your Great Plains
dealer. Refer to Weight Brackets, “Options,” page 45 for
part numbers and ordering information.
Refer to the charts below for the results of adding weights
to your drill. Always add an equal amount of weight to each
box frame. Never add more than 500 pounds to each box
frame.

Weight Chart, 30-Foot Drill
NOTE: Optional markers, harrows and small-seed attach-
ments add about 25 pounds per coulter. Completely load-
ing the grain or small-seed boxes adds about 100 pounds
per coulter.
Coulter Springs
The coulter spring length is preset at 10 inches, giving the
coulter an initial operating force of 400 pounds. This set-
ting is adequate for many difficult no-till conditions. For
lighter no-till conditions where rocks or other obstructions
are a problem, you can lengthen the springs to protect the
coulters from impact. In heavier conditions, shortening the
spring will increase coulter force. Refer to the chart below
for adjusting the coulter springs.

NOTE: Any attempt to reset the coulter spring length
shorter than 9 3/4 inches may contribute to premature fail-
ure of parts and warranty will be voided. If additional force
is necessary, add weights to the implement.
Individual Coulters
When coulters follow in tire tracks and do not give satisfac-
tory depth, individual coulters can be lowered by loosen-
ing the mounting clamps and adjusting the coulter to the
desired setting.
To retighten clamps, snug the hex-head clamp bolts (1)
just until the u-bolts are tight on each side of the spring
bar. Tighten nuts on u-bolts (2), then finish tightening the
hex-head clamp bolts.

NOTE: There may be as much as a 1/8-inch gap between
the clamp plates even when the coulter is mounted se-
curely.

IMPORTANT: Never lower any coulter more than 1 1/2
inches. Tire damage could result as the drill is folded.
Also note that when the drill is in the raised position,
ground clearance on lowered coulters is reduced.
