Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
This signal word is limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury, and includes hazards that are exposed when
guards are removed. It may also be used to alert against
unsafe practices.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury. It may also be used to alert against unsafe
practices.
Be Familiar with Safety Decals
▲ Read and understand “Safety Reflectors and Decals” in
your Operator manual.
▲ Read all instructions noted on the decals.
Prepare for Emergencies
▲ Be prepared if a fire starts.
▲ Keep a first aid kit and fire extinguisher handy.
▲ Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.

Introduction
Great Plains welcomes you to its growing family of new
product owners. Your Unit-Mount Row Cleaners (UMRC)
have been designed with care and built by skilled
workers using quality materials. Proper setup,
maintenance, and safe operating practices will help you
get years of satisfactory use from these accessories.
Description of Unit
The row accessories covered by this manual are rigid
toothed wheel row cleaners. They are provided as a
pivoting assembly that attaches to either its own mount
(UMRC) or to a unit-mount coulter (UMC-RC). In either
case, the row cleaner assembly is coupled to the
individual row unit (opener body). It follows the terrain
with the row unit, and raises and lowers with the row unit.
Adjustments are provided for setting the amount of
residue clearing desired.

Intended Usage
Use row cleaners on supporting implements equipped
with Great Plains 25 Series row units or any implements
with unit-mount coulters (UMCs). Use the row cleaners
for residue management with production-agriculture
crops only. Do not modify row cleaner for use with
attachments other than those approved by Great Plains.
Document Family
204-085M-A Installation, Operation and Parts Manual
(this document)
For routine operation and maintenance, you also need to
have your implement Operator and Parts Manuals.
The information in this manual is current at printing.
Some parts may change to assure top performance.
Supporting Implements for UMRC
Tighter row spacings and twin-row spacings do not allow
dual row cleaners. Some implements may only support
UMRC or UMC-RC only.
The row cleaners may not be compatible with other
planters and drills that have 25 Series row units. In
particular, 3-Point 25 Series drills often have insufficient
forward clearance to permit UMRC or UMC-RC use.

Assembly Instructions
Before You Start
Most accidents are the result of negligence and
carelessness, usually caused by failure of the operator to
follow simple but necessary safety precautions.
Allow no one to work on or use a row cleaner before
carefully reading this manual.
Sharp Object Hazard:
Row cleaner tines are sharp. The edges of row cleaner wheels
are sharp. UMC blades are sharp. Wear gloves when handling
these parts. Maintain awareness of installed coulters and row
cleaners when working in front of row units.
Perform these steps before installing your row cleaners.
1. Read and understand “Important SafetyInformation” starting on page 1.
2. Hitch the implement to a suitable tractor. Refer to the
hitching topic in the Operator Manual.
3. Position the implement in a level, dry, well-lighted
area. Pick a location with a clear surface beneath, so
that any dropped tools or parts can be easily located.
4. Unfold the implement.
5. Raise the row units (or leave them raised).
6. Install any lift locks provided.
Set all hydraulic circuits to neutral.
7. Shut off the tractor. Set the parking brake.
General Assembly Instructions
Start mounting with the left-most row unit of the
implement. Single-arm row cleaners are provisioned as
left and right hand pairs. Start with a left hand row
cleaner, and alternate left-right-left-right across the
implement.
Some fasteners may be loosely assembled. Remove
them before mounting that component. Due to evolving
manufacturing practices, some assemblies may already
be completely pre-assembled. If so, check that fasteners
are tight, and skip the unneeded assembly steps.
Torque values for fasteners are shown on page 20.
Wheel bearings are pre-greased and should not require
additional lubrication until the first service interval.
204-085M-ATable of ContentsIndex2014-02-12
Tools Required
• Basic hand tools, including an extension for any socket
or air wrench to be used
• Screw thread adhesive, such as Loctite

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).
1
In the case of plain 25 Series row unit, the UMRC
mounts on the front face of the row unit shank.
2
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.

Install UMC-RC Cleaner Arms
For Unit-Mount Coulter - Row Cleaners (disk coulters
present).
Refer to Figure 8 or Figure 9
(which depicts a shank mounted UMC and a dual RC arm).
UMC-RC kits do not include a mount weldment, as they
rely on mounts on the UMC brackets. If the UMCs
are not yet on the implement, install them before
installing the row cleaners, but do not install the coulter
blades until step 9 below.
Sharp Object Hazards:
If the UMC blades are already installed, exercise extra care
while installing the row cleaners.
The UMC itself is mounted directly on the row unit shank.
Refer to Figure 7 (which depicts a shank mounting)

5. Insert these in the lower/forward holes (for a 15 inch
coulter blade, upper/rear holes for a 14 inch blade).
6. Align the RC arm (, or) in between the
holes with the new bushing assemblies, and hold in
place with bolts.
7. Snug square shanks of bolts in arm holes, and
secure bolts with flat washers and flanged lock
nuts.
8. Clean and dry the surface of the gusset on the arm
