Row Unit Operation
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" (2.5 cm) 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:

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" (6 mm) 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 adjustment
Excessive down pressure can damage
coulter components when coulter strikes
an obstacle. Do not set down pressure
higher than needed for consistent soil
penetration.
