er. To replace, remove disk blade. Drive out roll pins
(2) and install a new spreader.

bearing and shank on one blade. Tighten bolt. On op-
posite side, reinstall blade with two (4) shims between
bearing and shank. Tighten bolt.
5. Check contact point between disk blades. Place a
piece of paper in top gap between disks blades. Bring
paper down until it stops. In lower gap place another
piece of paper. Bring paper up until it stops. Measure
the distance between two pieces of paper. The dis-
tance must be between 1/2 and 1 3/4 inches. Add or
remove shims as needed to get the correct contact
point.
6. Check that outside disk scrapers (5) are formed to
disk blades to help remove any mud. Bend and twist
scrapers to fit blades as necessary. After every 200
acres of planter operation, check outside scrapers for
proper adjustment and wear. Replace outside scrap-
ers as necessary.
