Installation Instructions 1
Before You Start
Each kit converts one coulter.
For each kit, inventory the contents per the “Parts List”
on page 6.
Review the instructions, to make sure the steps are
understood and what tools are expected.
Have the following items at hand:
• Original or updated Parts Manual for your implement
• basic hand tools
If necessary, move the implement to a dry well-lighted
location suitable for disassembly.
1. Raise and unfold the implement and, if equipped,
install lift cylinder locks. Otherwise secure it so that it
cannot lower during the work.
2. Secure the tractor.

Note on Disassembly

instructions assume this is possible.
On some planters and drills, and some row spacings, it
may be necessary to first dismount the coulters before
performing the update.
