Canola Field Update
If the inspection performed per “Pre-Requisites” on
page 29 indicates that your planter requires an update,
order one of the following kits per row:
Note: The kit includes one 817-991C canola seed disk.
Tools Required
• soft lint-free cloth and non-abrasive window cleaner
• 100% clear silicone sealant
• basic hand tools
• current parts manual (<multiple>) for parts ID
See Operator manual for details on steps 1-3, 5 and 19.
1.
Move planter to an area with adequate light, and a
clear surface for recovery of any dropped parts.
Perform a seed meter clean-out.
2.
For access to center rows, raise and fold planter.
3.
Remove rain covers and seed disks from all rows.
Perform remaining steps one row at a time, so that you
have unmodified and fully modified rows to compare to.
Starting with the right-most row may be the easiest. On
twin-row, locking up left rows of pairs may ease access.

disc for this update)

891-119C BRUSH, STRIP, SHORT
Install strip brushes in holder. Install holder and drop
brush in meter. Ensure strip brushes are seated low

that secures the seed
tube
