UMRC Installation or Update
For Unit-Mount Row Cleaners (no UMC disk coulters).
Refer to Figure 2 (which depicts dual RC mounting;
mounting of the single-wheel RCs is identical)
Unit-Mount Row Cleaners (UMRCs) are used only on
25 Series row units which either have no accessories
forward of the openers (other than a disk shield
).
In the case of plain 25 Series row unit, the UMRC
mounts on the front face
of the row unit shank.
Note: 25 Series row units with unit-mount coulters use
different models of row cleaner (UMC-RC), for
which the assembly instructions begin on page 10.
207-221A Update Kit - Prepare Site
If installing an all new row cleaner, and not updating an
existing row cleaner, begin at step 1 on page 8.

the old arm, before removing the old mount. Some parts

removed.

right wheels in separate collection areas.
