Seed Rate Adjustment- Front
Box
Adjusting Seed Cups:
All cups must be set the same in order to seed uniformly.
To check, set the inner and outer adjusting nuts to close
the seed cups. All cups should be completely closed. If
not, individual cups can be adjusted by loosening their
mounting bolts, moving the cups, and then re-tightening.
Pointer Adjustment
With cups completely closed, pointer should point to
groove in hex shaft marked “0”. If it does not,
adjust the nuts which clamp the pointer spring bolt to the
frame end plates.
