Row Unit Operation
Eccentric bushings in the wheel arm stop allow for lateral adjustment of covering discs/single press wheel assembly.
Use a ¾" wrench to loosen hardware attaching closing wheel arm to wheel arm stop. Use another ¾" wrench to turn
eccentric bushings until covering discs/single press wheel assembly is aligned with seed trench. Tighten hardware.
Two sets of holes in mounting arm locate covering discs for staggered or side-by-side operation.
Five sets of holes in each disc bracket allow ½" (1.2 cm) incremental blade depth adjustment.
Slotted holes in disc mount and bracket allow for 0° - 15° blade angle adjustment.
Adjust covering discs on all row units to similar settings.
