Feed Cup Adjustment

All cups must be set the same to seed uniformly. To
check, set the adjusting nut to 0-A. All cups should be
closed. Meter shutoff against washer in seed cup If not,
there are three adjustments to make as needed.
1. Jam nuts on both ends of the micrometer are used to
adjust all cups the same amount. See Figure 4-5.
2. Seed Box: Feed roll coupling which joins the left and
right seed shafts changes cups on the left box in
comparison with cups on the right box. To adjust
coupling, loosen jam nuts and set screws on coupling
RH shaft is treaded into coupling. Turn RH seed shaft
threading it in our out as needed to equalize meters.
Re-tighten set screws against flat side on seed shaft,
re-tighten jam nuts. See Figure 4-6.
3. Individual cups can be adjusted by loosening their
mounting bolts, moving cups and then re-tightening.
See Figure 4-7.
