Introduction
This manual has been designed to help you with
three extremely important issues: Operation, Safety,
and Maintenance. It is strongly recommended that
you read through the entire manual and review it
annually for:
• your own personal safety.
• the safety of others.
• helpful and effective operation
techniques.
• maintenance procedures.
• preventative maintenance.
Your authorized Degelman dealer can be
contacted for ordering any replacement parts,
decals, or manuals. Since many of our parts are
specially designed specifically for the Sidearm we
strongly recommend you always replace them
with genuine Degelman parts only.
This manual and its contents were current at the time
of its first printing. To increase product performance
and operation, some part modifications and changes
may occur that are not reflected in this manual.
Note: The description “Right”or“Left” as used in this
manual is determined by the direction the tractor
will travel while in use (unless otherwise stated).
Degelman is proud to welcome you to our rapidly
increasing family of high quality and dependable
product owners. This product was designed and
built specifically for you, the customer. Through our
research and with your input and feedback, we
present to you our 1820 Sidearm offset hitch.
Designed with durability, safety, and performance
in mind, the Sidearm is ready for years of quality
service. In order to help you keep your Sidearm in
top operating condition we have provided you with
this manual.
Your serial number is found on the serial number
plate attached to the Sidearm on the front left side
of the Sidearm near the support jack (shown in the
photo above).
It is important to record the serial and model
number of your Sidearm for proof of ownership and
for any required service or maintenance assistance.

Model
PTO Speed 540 RPM 1000 RPM
The 1820 Sidearm offset hitch enables the operator
to offset equipment, such as a rotary cutter, side to
side behind the tractor in a range of over 27 ft. from
left to right (13.5 ft in either direction). This feature
enables the operator to drive the tractor on level
ground in a more comfortable and safe environment
while the Sidearm offsets the equipment where
required.
The Sidearm steering is controlled with a 2-1/2” x
16” hydraulic cylinder attached to a main steering
arm. The Sidearm is available in either a 540 or
1000 PTO model and offers a variety of hydraulic
options that can be configured to meet your specific
requirements. The Sidearm’s four gearboxes,
1:1 ratio, are configured at 90° to each other. This
enables the Sidearm to offset and swivel at angles
of up to 50° from side to side while limiting stress
and wear on the gearboxes and internal drive
components.

How To Set Your Tractor
The Sidearm offset hitch is available in either a
540 or 1000 rpm PTO speed. Many tractors are
equipped with both 540 and 1000 rpm PTO modes.
Be sure that the PTO speed of the tractor matches
the Sidearm’s gearbox speed.
Caution: Under no circumstances should you try
to operate a 540 rpm PTO Sidearm with a 1000
rpm PTO tractor, and likewise do not operate a
1000 rpm PTO Sidearm with a 540 rpm PTO
tractor. Do not use PTO adapters. PTO adaptors
will cause driveline failure and possible tractor
damage, it will also invalidate your warranty.
1. Remove drawbar side locking pins and locate
drawbar into its center position to prevent it from
swinging.
2. Install drawbar locking pins.
3. Remove clevis or hammer strap assembly, if
equipped.
We recommend a tractor with all of the following
requirements:
• A full cab or at least one with ROPS (Rollover
Protective System).
• A working seat belt.
• At least 135 PTO HP.
• A sufficient amount of power and weight to
adequatly handle the machine.
The drawbar pin to PTO shaft end dimension should
be set to 16 inches for all PTO speeds.
Caution: Do not use a distance other than
16 inches or equipment damage may result.
(Please consult your tractor’s operator manual
for correct drawbar adjustment procedures.)
Caution: To prevent damage to the tractor
drawbar, avoid travelling at high speeds and over
rough terrain. Heavy drawn equipment can place
excessive strain on the drawbar.
Caution: To prevent machine damage, ensure the
3 point hitch will clear the Sidearm at all angles of
operation. You may
need to adjust the
position of your 3
point hitch.

Hydraulic Flow Setting
Caution: The tractor hydraulic flow setting that
controls the Sidearm steering cylinder should be
set to minimum. After practice and learning how
to adjust to the responsiveness of the Sidearm
steering, this flow setting may be adjusted slightly
higher according to user preference.
(Please refer to the tractor’s operator manual for
adjusting the hydraulic flow.)

correct drawbar hitch plate assembly onto the
tractor’s drawbar.
There are two optional hitch plate adapters:
502064 - For up to 3” Wide Drawbars
502232 - For 4” to 5” Wide Drawbars
Ensure you have the proper adapter for the
width of your drawbar. In the example shown,
the 3” Drawbar is being installed. Use the same
procedure for the 4” to 5” adapter as well.
Note: Please ensure the drawbar hammer strap
has been removed and stored if applicable,
and the hitch has been properly positioned
according to the procedures in the “How to Set
Your Tractor” section of this manual.
3. Now, loosely install the bottom plate using the
1” bolt, lock washer and nut.
You may wish to snug up
the this bolt but do not
fully tighten.

Swivel Hitch
Follow this attachment procedure at all times:
1. Clear the area of bystanders, especially small
children, before starting.
2. Be sure there is enough room to back the tractor
up to the machine.
3. Start the tractor and slowly back it up into the
Sidearm swivel hitch.
4. Stop the tractor,
place all controls
in neutral, set
park brake and
remove ignition
key before
dismounting.
5. Use the Sidearm
hitch jack to raise
or lower the hitch
to align with the
drawbar hitch
plate assembly.
Note: Typically, the top hole setting is used and
recommended. In severe angle ditch cutting,
you may wish to raise the machine by locating
the drawbar pin in the lower hitch hole.
6. Install the drawbar
pin and lock pin.
How To Hook-Up Your Sidearm
Attaching Sidearm to Tractor
Installing Safety Chain
• Install the safety chain between the tractor drawbar
cage and the Sidearm hitch.
• Provide only enough slack in chain to permit hitch to
swivel.
• Fasten chain back to itself with hook latch and ensure
chain is properly and securely attached.
Caution: Do not use safety chain by itself for
towing. Replace entire chain if any link or end
fitting is broken, stretched or otherwise deformed.
If replacing, use a chain with the strength rating
greater than the combined gross weight of the
Sidearm and any attached equipment (ie. rotary
cutter).
Top pin setting:
- lowers hitch height
- reduces drive angle
Reduced drive
angle, lowers
wear.
Important:
• Check the operating angle of your driveline from
the tractor PTO to the front Sidearm gearbox. The
greater the angle, the quicker the driveline wears
at the cross joint connections. You may even hear
noise from these connections. Due to the variance
in drawbar to PTO heights from many tractor
manufacturers, it is difficult to set a standard
configuration for hitch heights. The typical rule of
thumb is the lower the hitch setting the easier it is
on the driveline (less angle). However, in severe
ditch angles, you may need to raise this hitch
height.

-11-
143051 - Sidearm 1820 (12-April-2017)
Attaching PTO Driveline
1. Connect Sidearm electrical plug into appropriate
tractor receptacle.
2. Ensure cable does
not interfere with
or contact moving parts.
Connecting Lights
Danger: Shut off tractor engine before attaching
PTO driveline. Entanglement in rotating driveline
can cause serious injury or death.
1. Shut off tractor engine and remove key.
2. Check that the driveline telescopes easily and that
the shield rotates freely.
3. Lift tractor PTO shield.
4. Support driveline, pull back on collar, align splines
by rotating cutter driveline, and push driveline onto
tractor PTO shaft until collar snaps into place.
5. Push and pull yoke several times to ensure
driveline is locked. Do not pull collar, as this
will release the lock.
6. Lower tractor PTO shield back into place.
Caution: Under no circumstances should you try
to operate a 540 rpm PTO Sidearm with a 1000
rpm PTO tractor, and likewise do not operate a
1000 rpm PTO Sidearm with a 540 rpm PTO
tractor. Do not use PTO adapters. PTO adaptors
will cause driveline failure and possible tractor
damage, it will also invalidate your warranty.
1. Clean off dust covers and ends of hoses.
2. Firmly push in appropriate hoses into tractor
receptacles according to user preference.
3. Secure hoses as to not interfere with or
contact moving parts. Use the included
hose take up assemblies to help
secure the hoses, front and back,
(photo shown may differ from
actual product).
Attaching Hydraulics
If your Sidearm is equipped with the
selector valve option you will need to
route the switch box into the tractor
cab. It plugs into the female connector
end connected to the electrical plug
(refer to electrical plug image above).
There is an adhesive Velcro strip on
the bottom of the switch box that can
be used to help position the box in a
comfortable location.

Safe Operating Procedures
Operation
• Stay clear of rotating or moving parts! Contact or
entanglement with moving/rotating parts may result
in serious injury or death.
• Operate only with tractor equipped with ROPS
(Roll Over Protective System) and seatbelts.
• Ensure tractor PTO speed (540 or 1000 rpm)
matches the Sidearm gearbox speed or
drive components can be damaged.
• Operate tractor at rated PTO speed. Machine may
not perform properly if engine speed is too fast or
too slow. Excessive PTO speeds may cause driveline
failures that may result in serious injury or death.
• Familiarize yourself with stopping the tractor and
equipment quickly in case of a sudden emergency.
• To avoid tractor and equipment damage, do not turn
too tight. Be sure that the tractor tires do not contact
Sidearm or the Sidearm tires contact attached
equipment (i.e. rotary cutter).
• Slowly steer Sidearm down ditches.
• Be careful when operating machine on steep side
hills or slopes. Avoid excessively steep slopes to
avoid possible equipment damage.
• Slow down and carefully steer around road
obstacles.
• Normal ground speed range is 0 to 5 mph (8 km/h).
Use slower speeds when operating on or near
steep slopes, ditches, drop-offs, rough terrain,
overhead obstructions, power lines, or when
avoiding obstacles and other foreign debris.
• Never operate Sidearm in conditions of poor
visibility such as fog, darkness, or any conditions
that limit your clear visibility to less than 300ft
(100m) in front of and to the sides of the Sidearm.

public roads day or night, unless prohibited by law.
• When towing, travel at a reasonable and safe
speed. Never travel at a speed which does not allow
adequate control of steering and stopping. Do not
travel at speeds greater than that recommended by
the tire manufacturer.
• Check with local authorities regarding machine
transport on public roads. Obey applicable laws
and regulations.
• Keep to the right and yield the right-of-way to
allow faster traffic to pass. Drive on the shoulder, if
permitted by law.
• Stop slowly.
• Use caution when making corners or meeting traffic.
• Reduce ground speed when turning.
• Reduce speed considerably when travelling over
rough terrain.
• Beware of oncoming traffic and roadside
obstructions.
• Stay clear of any large bumps or deep depressions.
• Avoid possible loss of control or tractor overturn.
Tow only with correctly ballasted tractor.

Troubleshooting
The following section is a list of the most common
troubleshooting questions. If you do not find the
answer to your question here, try reviewing your
manual. If you still cannot find a solution, please
contact your Degelman service department.
1. I have the solenoid option, but my switch box
isn’t working?
• Check all connections are properly connected
from the switch box to the primary electrical plug.
• If this doesn’t work, check if the center (blue)
wire on the tractor electrical socket is live. In some
tractor models this wire may not be installed. If
this is the case, you have a couple of options. You
can properly install a wire (preferred method) or
you can relocate the wire from the center (blue) slot
on the Sidearm front cable plug assembly to the
brown slot. The tractor will then have to run with the
flasher/clearance lights on in order to activate the
switch. (Refer to the “Electrical Components” section
for Primary wiring).
2. I have the solenoid option and I seem to get a
battery drain from my Sidearm.
• There is always power to
the switch box. In order to
prevent battery drain be
sure to toggle the switch to
the off position when not in
use.
3. I find it difficult to steer the Sidearm because
it reacts too quickly.
• Check the Hydraulic Flow Setting on the tractor
hydraulic outlet that controls the Sidearm steering
cylinder. The setting should be set to minimum.
After practice and learning how to adjust to the
responsiveness of the Sidearm steering, this flow
may be adjusted slightly higher according to user
preference.
4. There seems to be a slight “shimmy” in the
steering beam. Is this normal?
• Some shimmy is normal due to required
manufacturing tolerances in the hydraulic cylinder
pins. If this becomes excessive, you may need to
replace the spring steel bushings in the cylinder lug
holes.
5. There seems to be some oil leaking/escaping
from the gearbox. Why?
• Some oil loss may occur through vent relief
valve located on the top of the gearbox when
operating the Sidearm. This is normal due to the
range of angles the Sidearm reaches when cutting
ditches.
• A consistent loss of oil may indicate damaged
seals. Damaged seal should be replaced
immediately to prevent damage to the gearbox.
Refer to the maintenance section of this manual.
6. My front driveline is damaged prematurely.
• Check to see if your PTO shaft end to drawbar
hitch pin hole distance is properly set to 16 inches.
If this distance is less than 16 inches, serious
damage may or may have already occurred to
front gearbox, driveline, or tractor PTO. If this
distance is too close (less than 16 inches), the
driveline could fully retract when climbing a ditch
and force extreme pressure on the gearbox or the
tractor PTO.
• Check the operating angle of your driveline
from the tractor PTO to the front Sidearm
gearbox. The greater the angle, the quicker the
driveline wears at the cross joint connections.
You may even hear noise from these connections.
Due to the variance in drawbar to PTO heights
from many tractor manufacturers, it is difficult
to set a standard configuration for hitch heights.
The typical rule of thumb is the lower the hitch
setting the easier it is on the driveline (less angle).
However, in severe ditch angles, you may need to
raise this hitch height.

Maintenance & Service
Before adjusting or servicing a
Sidearm connected to a tractor:
1. Park Sidearm and tractor on level ground.
2. Engage tractor parking brake and/or place
transmission into “Park”.
3. Disengage PTO.
4. Engage tractor parking brake and/or place
transmission into “Park”.
5. Relieve pressure in hydraulic system.
(See tractor Operator’s Manual).
6. Shut off tractor engine and remove ignition key.
7. Ensure all moving parts have stopped, then
remove PTO driveline from tractor.
Danger: To prevent serious injury or death to you
or others, and to prevent damage to your
equipment, always follow these safety messages:
• To prevent personal injury from unexpected
movement, ensure Sidearm is properly supported
and on a level surface before performing any
service work.
• Always relieve pressure before disconnecting or
working on hydraulic system.
• Do not make or allow any alterations or
modifications to the Sidearm, its components,
or its functions.
• Never lubricate, adjust, or service machine while it
is moving. Ensure tractor engine is off, all moving
parts have stopped, and the PTO driveline has been
disconnected before servicing.
• Ensure all guards, shielding, and their components
are maintained and in proper working condition.
Replace or repair any damaged components.
• Ensure all guards, shielding, and their components
are replaced and secured after service is complete.
• Maintain the product safety decals and replace any
decals that are damaged, missing or unreadable.
1. Always place all tractor hydraulic controls in neutral
before dismounting.
2. Always relieve pressure before disconnecting or
working on hydraulic system.
3. Make sure that all components in the hydraulic
system are kept in good condition and are clean.
4. Replace any worn, cut, abraded, flattened or
crimped hoses and metal lines.
5. Do not attempt any makeshift repairs to the
hydraulic lines, fittings or hoses by using tape,
clamps or cements. The hydraulic system operates
under extremely high-pressure. Such repairs can
fail suddenly and create a hazardous and unsafe
condition.
6. Wear proper hand and eye
protection when searching
for a high-pressure hydraulic
leak. Use a piece of wood
or cardboard as a backstop
instead of hands to isolate and
identify a leak.
7. If injured by a concentrated
high-pressure stream of hydraulic fluid, seek
medical attention immediately. Serious infection
or toxic reaction can develop from hydraulic fluid
piercing the skin surface.
8. Before applying pressure to the system, make sure
all components are tight and that lines, hoses and
couplings are not damaged.
Think SAFETY! Work SAFELY!
Warning: High pressure fluid can pierce skin
causing serious injury or death. Relieve pressure on
system before repairing or adjusting. Wear proper
hand and eye protection when searching for leaks.
Use wood or cardboard instead of hands. Keep all
components in good repair.
