“V” CLOSING WHEEL ADJUSTMENT
WARNING: Raise planter to transport position and install all safety locks before
adjusting closing wheels.
Angled closing wheels trail behind the seed opener to close the seed trench left by the opener. Adjusting
spring pressure permits proper firming of the soil beside the seed rather than directly above it. An eccentric
bushing allows centering the closing wheel on the row to properly apply pressure on both sides of the seed
when closing the trench. When adjusted properly, the closing wheels are centered, tighten the bolts holding
the closing wheel to the row unit.

After setting the planter depth to the correct depth, check the operation of the closing wheels. The closing
wheels must apply enough down pressure to close the seed trench and insure good seed to soil contact. If
the seed trench is not being closed properly increase the closing wheel pressure by moving the closing
wheel lever rearward.
Closing wheels must not sink into the soil too deeply or the seed placement could be adversely affected,
especially when planting shallow. If the closing wheels are applying too much pressure and the seed is
being moved by the closing wheels, decrease by moving the lever forward.
Light soils usually require less down pressure, heavy soils more.

In certain conditions, seed to soil contact and residue flow can be improved by spacing the closing wheels
further apart and/or staggering them. to space them further apart, remove the bolt and nut holding the
closing wheel to the closing wheel arm, place 5/8” washers (not provided) between the closing wheel and
the arm and re-assemble the closing wheel to the arm.
Two mounting holes for each closing wheel are provided in the closing wheel arm. To stagger the closing
wheels, remove one closing wheel from the arm and re-assemble it in the other hole in the closing wheel
arm.
LUBRICATION
Oil the closing wheel bushings weekly with a general-purpose oil.
