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 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.
Check operation of covering discs/single press wheels after adjusting planting depth. Initial press wheel down force
spring setting is 63 mm between mounting arm tab and locking nut. Loosen
½
" locking nut and turn adjusting bolt in to
increase down force or out to decrease down force. Tighten locking nut against spring plug. Adjust all row units to a
similar setting.
COVERING DISCS/SINGLE PRESS WHEEL ADJUSTMENT

bushings provide lateral adjustment. Use a
¾
