Note: If a lower shear bolt ever fails during operation,

replace it with an identical (#802-720C). Do not use a

high grade bolt, or equipment damage may result.

3) Tighten all three nuts to Grade 5 torque specification

(50 foot-pounds).

4) Ensure that all rows have identical adjustments. The

only time they may differ is for rows in tire tracks.

Furrower Disc Angle Adjustment:

This setting needs to be adjusted per the furrow profile

and conditions. The other furrower adjustments are

often satisfactory at their factory setting.

1) Loosen the eight nuts (15) on the slotted bolts and

pivot bolts. Ensure that both top and bottom bolts are all

loose.

2) Set the disc angle to the desired setting and re-tighten

the nuts.

Furrower Disc Height Adjustment:

If it is necessary to change the furrower height, first see

if the channel/mount adjustment suffices.

1) Loosen both nuts (16) on one disc side and slide the

mount up or down on the channel. Re-tighten the nuts

when adjusted.

Cultivator Height Adjustment:

1) Loosen the nuts (17) at the lower shear bolts, and the

lock nut (18) at the upper pivot bolt.

2) Slide the shank (19) up or down to the desired height.

The factory setting is 10 1/2 inches, measured from the

bottom of the row unit frame to the top of the sweep

shank weldment.

3) Tighten the lower nuts and upper lock nut to 50 foot-

pounds.

Note: If the lower shear bolt is ever failed by a

field obstruction, replace it with an identical (802-720C)

HHCS 7/16-14x3 1/2 GR5 PLT. Do not use a higher

grade bolt, or equipment damage may result. Using a

lower grade bolt may result in nuisance shears.

Cultivator Pitch Angle:

The upper cultivator mounting bolt (20) passes through

a slot in the shank, allowing some pitch angle adjust-

ment. The factory setting is maximum nose up.

1) Loosen both the upper (20) and lower (21) nuts.

Adjust the pitch angle and secure both nuts.
