looseness in the holder and between the blades.
Some looseness is required for proper operation.

1.
Remove side gauge wheels from arms to access
row-unit disks and scrapers.
2. With the unit raised, check blade spreader for
wear. Replace spreader if it is 1 ⁄
2
in (13mm) wide or
narrower. To replace, remove disk blade , drive out
roll pins , and install new spreader.
3. When reinstalling disk blades, put two shim
washers
between bearing and shank on each
blade. Tighten bolts.
Note: You may need fewer inside shim washers on worn
disks.
4. Check that outside disk scrapers are formed to
disk blades to help remove any mud. Bend and twist
scrapers to fit blades as necessary. After every
200 acres (80 hectares) of operation, check outside
scrapers for proper adjustment and wear. Replace
outside scrapers as necessary.
