Seed Disc Wear
Inspect the seed disc for wear at disc attaching holes,
seed loading slots and seed pockets. Most wear will be
found between seed loading slots.To measure for wear,
lay a straight edge across the surface of disc. Measure the
gap between disc and straight edge. If this measurement
is greater than 0.075” and accuracy is starting to drop off
at higher meter rpms, then replace seed disc.
