ROW UNIT MOUNTED NO TILL COULTER
Row unit mounted no till coulters with 1" bubbled, 1" fluted (8
flutes) or ¾" fluted (13 flutes) blades may be used on row units
(¾" fluted shown). Four quick adjustable down force springs
are required per row when using row unit mounted no till
coulters. See
“Quick Adjustable Down Force Springs Option” on
page 3-4
.
Coulter blade can be adjusted to one of four ½" incremental
settings in the forked arm. Initial location is the top hole.
Move blade as it wears to one of the three lower hole to
maintain coulter blade at or slightly above opener discs. Adjust
coulter below depth of double disc opener blades in very hard
soil conditions such as compacted wheel tracks to improve opener penetration and cutting of surface residue.
Check operating depth by setting planter down on a level concrete floor and checking relationship between coulter
blade and row unit opener blade. Make sure planter is level and coulter is square with planter frame and aligned with
row unit disc opener.
NOTE: Torque ” spindle hardware to 120 ft-lb (162.7 N-m).

SPIKED CLOSING WHEEL
Spiked closing wheels crumble the sidewall, allowing roots to pentrate soil. They
can be used on pull row units and push row units.
Align spiked closing wheels straight across from each other, in most forward
holes on closing wheel arm. Set the wheels 1" - 1¼" (2.5 - 3.1 cm) apart at the
closest point.
