Row Unit Operation
RESIDUE WHEELS (FOR FRAME MOUNTED COULTER)
Residue wheels attach to frame mounted coulter with two
cap screws and sleeves allowing the unit to free-float. A
2-position spindle bolt mounting positions wheels interlocked
or staggered. Depth adjustment is made with a spring-loaded
cam and pin with 11 positions in ¼" increments. A high point
on the cam allows wheels to be locked up.
A weed guard on the inboard side of each wheel helps prevent
weed wrap which can cause premature bearing failure.

FRAME MOUNTED COULTER (PULL ROW ONLY)
Frame mounted coulters with 1" bubbled, 1" fluted (8 flutes) or ¾"
fluted (13 flutes) blades are used on pull row units only.
Springs provide down pressure on coulter for maximum penetration
while exerting less shock load on row unit.
Initial coulter blade location is in top hole. Relocate blade to one of
lower two holes (1" increments) as wear occurs or for deeper blade
operation.
DOWN PRESSURE ADJUSTMENT
Raise planter. Turn spring adjustment bolts clockwise to increase or counterclockwise to decrease down pressure. Set
both springs to specification shown in following table:
End flush with
spring anchor bar
Extended ½" through
spring anchor bar
All threads used
275 lb (124.7 kg) 400 lb (181.4 kg) 500 lb (226.8 kg)

Excessive down pressure can damage
coulter components when coulter strikes
an obstacle. Do not set down pressure
higher than needed for consistent soil
penetration.
