Install Down Stop (UMC-RC Only)
If you have installed UMRCs, the adjuster hardware is
already installed. Skip this section and make final
adjustments per the instructions in the next section.
The height adjustment for UMC-RC units is a sliding
stop.
21. Select one:
207-148H UM ROW CLEAN DOWN STOP WLDM
22. Set two sets of:
802-270C RHSNB 5/16-18X1 1/2 GR5
803-008C NUT HEX 5/16-18 PLT
804-009C WASHER LOCK SPRING 5/16 PLT
804-036C WASHER FLAT 5/16 SAE PLT
Note: On single-wheel arms, the down stop mounts on
the side of the arm with the wheel. On dual-wheel
arms, the down stop may be mounted on either
side, and you may want to select the location on a
per-row basis, for ease of access for adjustments.
23. Swing the cleaner arm up until the tines are well
above the height of the bottom edge of the row unit
opener disks. Support the arms at this height.
24. From underneath the arm , orient the tip end of the
down-stop forward (longer bolt slot aft), and slide
the down stop up onto the arm. Temporarily secure
with one or two bolts
.
Insert the bolts from the inside of the arm. Placing
the threads outside the arm minimizes collection of
residue during operations.
25. Place a flat washer , and then a lock washer
onto each bolt, and loosely add a nut .
26. If you know the initial height at which you desire to
operate the cleaner (from the next section), set the
cleaner arm at that height and support it there.
27. Slide the adjuster back until it contacts the coulter
bracket. Secure the nuts. Remove the support
holding up the arm.
