10HD Unit-Mounted Coulters
Unit-mount coulters (UMCs) are available only for mod-
els 3N-4010HDF, and are an alternative to
frame-mounted coulters (page 120). Only one type of
coulter at a time can be installed. UMCs attach directly to
the 10HD row unit, and the coulter blade maintains a pre-
cise relationship to the opener disk (seeding) depth.
UMCs are suitable for lighter no-till and conventional till-
age conditions. Their down-force is limited to what the
10HD row unit can provide. In challenging conditions,
weight kits may be required.
UMCs are dealer-installed. Order one kit part number
per row. Weight is 40 lbs (18kg) per row.
For operation, see “Unit-Mounted Coulter Adjust-
ments” on page 76.

10HD Lock-Up Pin
If rows are shut off with seed tube plugs (page 121), you
can reduce unnecessary wear on the unused row units
by locking them up. One one per row unit locked-up.
