Row Unit Operation
FRAME MOUNTED COULTER (PULL ROW)
Frame mounted coulters with 1” (25 mm) bubbled, 1” (25 mm)
fluted (8 flutes) or
¾
” (19 mm) 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 (25 mm increments) as wear occurs or
for deeper blade operation.
DOWN PRESSURE 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.
NOTICE
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 (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 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.
NOTE: Opening in weed
guard must face down.
Frame mounted coulter residue wheel
Tined wheel forward mounting positions
cannot be used on four rows behind axle
due to inadequate clearance.
