ASSEMBLY INSTRUCTIONS
STEP 3. Install the wheels, using the spacers as needed, so that the distance at the
bottom of the wheels is approximately 2-1/4”-2-1/2”.
STEP 4. Adjust the close wheel spring tension as necessary. If the seed trench is not
being closed properly, increase the closing wheel spring pressure. Closing wheels must
not sink into the soil too deeply, 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 closing wheel pressure.
Light soils usually require less down pressure; heavy soils more down pressure.
Installation Tip: When using one spike and one
rubber wheel: Install two spike wheels on a row unit
to determine the correct amount of spacers for
proper distance of the spike wheel from the seed,
reinstall the rubber wheel and use the same amount
of spacers on the spike wheel for the other row
units.
