Seed Disk Maintenance
When removing seed disks, inspect for wear and
damage. If there is any seed dust or treatment
buildup in the cells (1), or along the raised wiper
ridges (2), clean the disks and reinspect.
Replace the disks for:
 Chips at the outer edge (3). These chips will leak air.

Chips at the edges or in surfaces of the cell
pockets (1). These chips can leak air and/or
affect singulation.
 Cracks over 2 inch (5 cm) long in the working
face (4) of the disk, or any cracks in the ridges or
grooves on the face.

Warping - if any part of the disk does not press
firmly on the seed drop brushes in operation.

Wear - if a wiper ridge (2) is worn away.
If the cells are worn through, or the air ports (5)
have enlarged, replace the disk.
Cleaning and Storing Seed Disks
Possible Chemical Hazard
Seed disks will have talc and graphite residue,
and may have residue of hazardous seed
treatments. Do not wash disks where food is
prepared or where cookware or dinnerware is
washed. Wear gloves when washing disks.
Avoid spray.
Use warm or hot water, mild soap, and a sponge or
soft brush to remove buildup on seed disks.
If disks are washed, allow to dry completely before
storage.
Keep original shipping cartons for disk storage.
Otherwise, store on edge (not leaning), or stacked
horizontally on a spindle, to eliminate any risk of
warps.
Any seed residue on disks may attract pests. Fully
enclose dry disks to prevent rodent damage.

Chains
Chain Lubrication
Lubricate chains any time there is a chance of
moisture, and when being stored at the end of the
planting season. Use a multi-purpose spray
lubricant.
Chain Slack
Initially check the drive chains after the first 8 hours
of drill use. The new chain slack tends to increase
during the first few hours of operation due to seating.
After the first 8 hours, check the chains seasonally.
1. Measure the span (1) for allowable slack:
Locate the longest span of each chain (usually
the span which does not run through the idlers).
2. Determine the ideal slack:
3. Measure the current slack (2):
At a right angle to the chain span at the center of
the span, deflect the chain in both directions. The
slack is the distance of the movement.
4. Adjust the idlers for ideal slack.
Chain Clips
Whenever mounting a chain, ensure the clip at the
removable link is positioned to minimize snags.
Install the clip with the open end facing away from
the direction of chain travel.
