Disk Spreaders and Scrapers
Sharp Object Hazard
Disk blades are sharp. To avoid serious injury,
wear gloves when working in this area.
1. Remove the side depth wheels from the arms to
access row unit disks and scrapers.
2. With the unit raised, check the blade spreader (1)
for wear. Replace the spreader if it is 1/2 in.
(13mm) wide or narrower. To replace:
a. Remove the disk blade (2).
b. Drive out the roll pins (3).
c. Install the new spreader.
For proper operation, the scraper separator must
be a little loose in the holder and between the
blades.
3. When reinstalling disk blades, put two shim
washers (4) between the bearing and shank on
each blade. Tighten the bolts.
You may need fewer inside shim washers on
worn disks.
4. Check that outside disk scrapers (5) are formed
to the disk blades to help remove any mud. Bend
or twist the scrapers to fit the blades as necessary.
After every 200 acres (80 hectares) of operation,
check outside scrapers for proper adjustment
and wear. Replace the outside scrapers, as
necessary.

Seed Flap Replacement
To replace a seed flap (1):
1. Use a needle nose pliers or similar tool to grasp
the T at the top of the flap.
2. Pull up to pull the flap up out of the metal bracket
(2).
3. Push the new seed flap down through the metal
bracket until the flap snaps into place with the T
top resting on top of the bracket.

Chain Maintenance
Chain Lubrication
Inspect and lubricate chains regularly. Lubricate
chains any time there is a chance of moisture and
when stored at the end of the planting season. Use a
multi-purpose spray lubricant.
When performing periodic lubrication, check chain
condition. Replace chain if any frozen kinks are not
corrected by lubrication.
Chain Slack
New chains may slack during the first few hours of
operation.
