Overview
TO THE NEW OPERATOR OR OWNER
The Degelman Signature Series Rock Pickers are
designed to efficiently gather rocks from 1-3/4 to
24 inches (45 to 600mm) diameter and debris
from fields. Many of the features incorporated
into this machine are the result of suggestions
made by customers like you.
It is the owner’s or operator’s responsibility
to read this manual carefully to learn how to
operate the machine safely and how to set it to
provide maximum efficiency. Safety is everyone’s
business. By following safe operating practices, a
safe environment is provided for the operator and
bystanders.
The manual will take you step-by-step through
your working day. By following the operating
instructions in conjunction with a good
maintenance program, your machine will provide
many years of trouble-free service.
PRINCIPLES OF OPERATION
The Rock Picker is a framework of steel bars called a
grille that moves along the surface of the ground to
gather rocks and debris. A rotating paddle moves
along the top of the grille to move the rocks and
material into the hopper box. When the hopper
box fills, it is emptied by dumping out the back.

Before using:
1. Read Safety Info. & Operator’s Manual.
2. Complete steps in “Pre-Operation Checklist”.
3. Lubricate all grease points.
4. Check all bolt tightness.
After operating for 2 hours:
1. Retorque wheel bolts.
2. Check all hardware. Tighten as required.
3. Check all hydraulic system connections.
Tighten if any are leaking.
4. Tighten chain.
8. Use a long pole or bar to dislodge material
from paddles or grille. Pressure in hydraulic
system and paddle spring tension can cause
paddles to kick back if they are jammed.
9. Be careful when working around or maintaining
a high-pressure hydraulic system. Ensure all
components are tight and in good repair before
starting.
10. Clean all reflectors, lights and the SMV sign
before transporting on a highway or public
road. Be sure to check with local highway
authorities and comply with their lighting
requirements.
11. Stay well back from machine when operating to
prevent being hit by flying rocks. Keep others
away.
12. Turn to the left when manoeuvring to keep the
tractor away from the path of flying rocks.

Preparation
PRE-OPERATION CHECKLIST
It is important for both personal safety and
maintaining the good mechanical condition of
the machine that this pre-operational checklist
be followed.
Before operating the machine and each time thereafter, the following areas should be checked off:
1. Lubricate the machine per the schedule
outlined in the “Service & Maintenance Section”.
2. Use only a tractor of adequate power (70 hp
minimum) and weight to carry the Rock Picker.
3. Ensure that the machine is properly attached
to the tractor using a drawbar pin with
provisions for a mechanical retainer. Make sure
that a retainer such as a Klik pin is installed.
4. Ensure that a safety chain on the hitch is
installed.
5. Check tires and ensure that they are inflated
to the specified pressure: 36 psi (248kPa).
6. Check oil level in the tractor hydraulic
reservoir. Top up as required.
7. Inspect all hydraulic lines, hoses, fittings and
couplers for tightness. Tighten if there are leaks.
Use a clean cloth to wipe any accumulated
dirt from the couplers before connecting to the
tractor’s hydraulic system.
8. Check all roller chains and sprockets for
proper alignment and tension. Adjust for
tension as required.
TRACTOR PREPARATION
Follow this procedure when selecting and preparing
a tractor for use with the machine:
1. Use only a tractor of sufficient power and
weight to adequately handle the machine. It
is recommended that the tractor have at least
70 PTO horsepower for normal operating
conditions, 100 PTO horsepower for hilly
conditions. (Note:Tractors with duals
are not recommended as the right hand
tires push the rocks into the ground.)
2. It is recommended to pin the drawbar in its
centre draft position.
3. Use only a drawbar pin with provisions for a
mechanical retainer such as a Klik pin. Always
install the retainer.
4. Always attach a safety chain between the
tractor and the machine to prevent unexpected
separation.
5. It is not recommended to use a tractor that is
equipped with duals. The right outer tire will
drive over the rocks, push them into the ground
and make them difficult to pick up with the
grille.
PTO Models
6. The drawbar pin to PTO shaft end dimension
should be 14 in. (540 PTO).
14 inches
9. Inspect all moving and rotating parts.
Remove any debris that has become entangled
in them.
10. Make sure that all guards and shields are
installed and secured in position.
11. Check the paddles, grille and hopper box.
Remove any rocks or debris that have become
jammed in any of the components.
12. Check the oil level in the gearbox. Top up
as required (PTO models).
13. Insure that the PTO driveline is securely
attached on both ends and can telescope easily.
Check that the PTO driveline shield rotates
freely.
142922 - Signature 6000/7200 (16-August-2017)
IMPORTANT: Do not use on a tractor equipped
with a PTO shaft adapter to prevent
mismatching of PTO speeds and over
telescoping of the driveline.
WARNING: Use extreme care
when working around a high
pressure hydraulic system. Make
sure all connections are tight
and all components are in good
repair. Wear hand and eye
protection when searching for suspected leaks.

dry area that is free of debris and foreign objects.
Follow this procedure when attaching:
1. Clear the area of bystanders and remove
foreign objects from the machine and working
area.
2. Make sure there is enough room to back the
tractor up to the hitch pole.
3. Start the tractor and slowly back it up to the
hitch point.
4. Stop the tractor engine, place all controls in
neutral, set park brake and remove ignition key
before dismounting.
5. Use the hitch pole jack to raise or lower the pole
to align with the drawbar. Ensure that the rock
picker hitch pole is parallel to the ground.
6. Install a drawbar pin with provisions for a
mechanical retainer such as a Klik pin.
Install the retainer.
7. Install a safety chain between the tractor
drawbar and the hitch pole.
8. Connect the hydraulics. To connect, proceed as
follows:
• Use a clean cloth or paper towel to clean the
couplers on the ends of the hoses. Also clean
the area around the couplers on the tractor.
• Remove the plastic plugs from the couplers and
insert the male ends.
If the direction of motion is wrong, reverse the
couplers.
9. PTO Models: Connect PTO driveline to tractor.
10. Raise the hitch jack and rotate it 90º to place in
its stowed position.
11. When unhooking from the tractor, reverse the
above procedure.
Occasionally air may become trapped in the
hydraulic circuit, making it necessary to “bleed”
the circuit.
To perform this operation cycle the hydraulics
several times or especially on older tractors,
temporarily loosen an easily accessible hose
fitting enough to allow any trapped air to escape
while cycling the hydraulics. Retighten fitting.
Connect the Hyd lines
• Clean off couplers on
hose & tractor with cloth
• Remove plugs & insert
couplers
- Ensure pressure & return
lines are matched up on
same valve bank
PTO: Connect the PTO Driveline
• Check that the PTO driveline
telescopes easily and the shield
rotates freely
• Attach the driveline to tractor by:
- Retracting the locking collar
- Slide the yoke over the shaft
- Push yoke until lock collar clicks
into position
Turn jack sideways
for field position
Adjust pin in
hitch clevis to
set pole height.
Ensure hitchpole
is parallel to ground,
adjust with jack.
Always park on a level surface clear of debris
and obstacles.

4. Raise or lower the unit to give the required
distance.
5. Reinstall the mounting bolt in the appropriate
matching holes.
HYDRAULIC FLOW CONTROL VALVE
(Optional Hydraulic Drive Models)
For tractors that are not equipped with a built-in
flow control valve, this unit will be necessary to
regulate the rate of oil flowing through the picker
hydraulic motor which in turn determines the reel/
paddle speed.
The flow control valve in the hydraulic circuit is used
to adjust the motor speed. To adjust, follow this
procedure:
FLOW CONTROL VALVE ADJUSTMENT
1. Loosen thumb nut on swinging dial.
2. Move dial to desired setting.

Preparation
ROCK PICKER PREPARATION
1. Hitch Pole “Field/Transport” configuration:
The hitch pole has a “transport” position that
is normally used when the machine is new or
when it will be transported for long distances to
bring the body of the machine as close behind
the tractor as possible.
The hitch pole must be changed to “field”
position before starting to work. “Field” position
will swing the body of the machine over to clear
the tires of the tractor.
NOTE:This Rock Picker has either standard
“manual adjustment” or optional “hydraulic
adjustment” for positioning the hitch pole.
To change to “field” position with the optional
simply retract the hitch pole cylinder to its
closed position.
To change positions with manual adjustment,
follow this procedure:
a. Remove the hardware shown holding the
pole in transport.
b. “Jack-knife” the pole into field position.
c. Reinstall the hardware just removed.
To change positions with hydraulic adjustment,
follow this procedure:
a. Remove the hardware shown holding the
pole in transport position (shown) and store.

b. Retract the hitch pole cylinder to its closed
position (“field” position).
c. Reverse order for “transport” position.
2. Grille Preparation:
Fully retract the dump cylinder to take the
weight of the grille off the red transport pin.
Remove the red
transport lock pin
from its transport
position.

Operation
OPERATING
Refer to these operational hints before starting:
1. Material size:
The machine was designed
1-3/4” to 24”
to pick and unload rock
and debris ranging in size
from 1-3/4 to 24 inches
(45 to 600mm) in diameter. Smaller pieces will
fall through the spacing in the grille and larger
rocks will stall the paddle drive.
2. Operator’s Responsibility:
Every operator should read this manual and
be instructed in safe operating procedures. An
untrained operator is not qualified to operate
this machine and could place themselves or
bystanders in danger.
3. Grille Height:
The grille should be lowered to allow the front
of the teeth to skim the ground surface. This
will provide the best gathering angle and
allow a minimum amount of dirt being carried
into the hopper box.
4. Ground Speed:
Operating speed will vary
according to:
• rock size and density
• whether spot picking

or windrow picking
Experience will teach you the correct
combination of forward travel speed and reel
RPM to suit field conditions:
Normal Operating Speed:
As a rule 4 to 6 MPH (6 to 10 km/h) is a
normal operating speed.
Slow the travel speed when picking heavy rock
windrows.
All rocks should be laying on top of the ground
for best results when picking. Rocks that are
partially submerged or have been run over
by the tractor tire are difficult to pick. In these
conditions, the grille can be set to momentarily
run below the ground surface in an attempt to
pick the rock. However, raise the grille back to
skimming the surface to reduce the amount of
dirt going into the hopper.
IMPORTANT: Do not use the Rock Picker
grille to pry out deeply buried rock or debris.
Grill teeth striking a buried rock will shock the
machine and damage it.
5. Buried Rocks:
The machine is only designed to pick up
material that is loose and on top of the ground.
Lodged or solid objects will shock load the
frame of the machine when trying to pick them
up and cause failures. They should be dug out
by hand and placed on top of the ground.
142922 - Signature 6000/7200 (16-August-2017)
-11-
Operation
6. Reel Speed:
The purpose of the reel is to sweep the rocks
from the front of the grille over the grille
framework and into the hopper box. The
spring loaded paddles should keep the grille
framework clear of rocks by moving them into
the hopper.
DANGER: There is a danger that the paddle
will catch the rocks and throw them forward if
the real speed is too fast.
Spot Picking: Best results are obtained when
the reel is running 5% to 40% faster than
ground speed.
Windrow Picking: The reel must be allowed to
sweep the rocks from the grille even when
there are large numbers as in windrows.
To control the number of rocks entering the
machine, reduce the forward speed.
Hydraulic Drive Models
The reel and paddle speeds are determined
by the flow rates through the hydraulic
system. Increase or decrease the reel speed by
adjusting the flow control valve (optional) at
the front of hitch pole or by the control valve
on the tractor.
IMPORTANT:When stopping reel always
place the tractor hydraulic lever into float
position or for tractors not equipped with float
position be sure to idle tractor speed down
before placing the hydraulics into neutral.
Never reverse reel direction without first
completely stopping reel. Failure to do this will
result in costly hydraulic motor damage.
PTO Drive Models
The reel and paddles always run at a constant
speed as determined by the PTO input speed
and the drive ratios through the gearbox. The
ratio of reel speed to ground speed is changed
by changing ground speed. Slowing ground
speed allows the paddles to sweep over the
grille more frequently and clear the rocks.
This is particularly important when picking up
heavy rock windrows.
7. Loading/Dumping:
a. Loading: The machine can be loaded until
the hopper box is filled and rocks stay on the
back edge of the grille. Do not overfill the box
as to overflow onto the grill. It is possible that
the paddles will carry the rocks over the top
of the paddle and throw them out.
When hopper box is full, stop the reel to
prevent throwing rocks.
DANGER:Rocks can be thrown from
machine. Stand well clear of machine when
operating. Keep others away.
b. Dumping: The hopper box is
unloaded by extending the
unloading
cylinders on
the box.
Ensure no obstructions under
grill or near lift bracket areas.
• When backing up with a full load, switch the
hitchpole back to the transport position. This
will prevent damage to the frame.
• Be sure the machine is on level ground when
raising the hopper box to unload. Uneven
ground conditions can cause the box to tilt
and could be dangerous or result in damage
to the machine.
• Ensure there are no obstructions below the
grille/grate area or the side cylinder lift
bracket area when dumping. Obstructions
in these areas can cause extreme loading
on pins and brackets due to over-extension
of the cylinders and result in damage to the
machine.
WARNING:Stay clear of the machine and
surrounding area when unloading. Keep
others away.
WARNING: Ensure there are no obstructions
below the grille/grate area or the side
cylinder lift bracket areas when dumping.

-12-
Operation
8. Safety Area:
Always treat the machine with the utmost
respect when it is operating. Since the paddles
are all loaded with strong springs, they can
catch and throw rocks a considerable distance
as they move around the reel. Although the
most common direction is in the plane of reel
motion, they can also hit the frame and bounce
off to the sides.
It is recommended that the tractor be turned to
the left as much as possible when picking to
keep it out of the path of flying rocks. This has
the added benefit of eliminating the right hand
tractor tire from running over rocks and pushing
them into the ground.
9. Jamming/Unplugging:
WARNING:Never use hands. Never get your
head or arms into the machine. Stay clear
of the paddle when removing any lodged
material. The paddles could kick back from
hydraulic pressure or spring tension. Always
use a long bar to remove object.
Small rocks or debris can get jammed between
the grille, paddle or frame jamming the reel
and stopping it from turning. To unplug, follow
these procedures:
a. Hydraulic Drive Models ONLY
IMPORTANT:
Never reverse reel direction without first
completely stopping reel. Failure to do this
will result in costly hydraulic motor damage.
When stopping reel always place the tractor
hydraulic lever into float position.
For tractors not equipped with float position
be sure to idle tractor speed down before
placing the hydraulics into neutral.
WARNING:
Turn to the left to
keep yourself out of
the path of potential
flying rocks.
WARNING:
Rocks can ricochet
off to the side.
Keep Bystanders
Away!
• After reel has completely stopped as
described above, move the hydraulic control
lever the other direction to reverse the
hydraulic motor. Reversing the reel will in
most cases dislodge the jammed rock.
• If it does not unplug the machine, proceed to
Step b.
b. Hydraulic or PTO Drive Models
• Lower grille to ground
• Stop tractor engine
• Place all controls in neutral,
• Relieve the pressure in hydraulic system
• Set park brake
• Remove ignition key.
• Use a long pry bar (not hands) to dislodge
the material.

MAINTENANCE SAFETY
• Review the Operator’s Manual and all safety
items before working with, maintaining or
operating the Rock Picker.
• Lower grille and hopper box, stop the tractor
engine, place all controls in neutral, set park
brake, remove ignition key and wait for all
moving parts to stop before servicing, adjusting,
repairing or unplugging.
• Keep hands, feet, clothing and hair away from
all moving and/or rotating parts.
• Clear the area of bystanders, especially
children, when carrying out any maintenance
and repairs or making adjustments.
• Place safety stands or large blocks under the
frame before removing tires or working beneath
the machine.
• Be careful when working around
or maintaining a high-pressure
hydraulic system. Wear proper
eye and hand protection when
searching for a high-pressure
hydraulic leak. Use a piece of wood or
cardboard as a backstop when searching for a
pin hole leak in a hose or a fitting.
• Always relieve pressure before disconnecting or
working on hydraulic system.
FLUIDS AND LUBRICANTS
1. Grease: Use an SAE multi-purpose
grease with extreme pressure (EP)
performance. Also acceptable is an
SAE multi-purpose lithium base grease.
2. Gearbox Reservoir Oil: Use an SAE
85W90 gear oil for all operating
conditions. Reservoir capacity: 1 quart (1litre).
3. Storing Lubricants: Your machine can operate at
top efficiency only if clean lubricants are used.
Use clean containers to handle all lubricants.
Store them in an area protected from dust,
moisture and other contaminants.
GREASING
1. Use only a hand-held grease gun for all greasing.
2. Wipe grease fitting with a clean cloth before
greasing, to avoid injecting dirt.
3. Replace and repair broken fittings immediately.
4. If fittings will not take grease, remove and clean
thoroughly. Also clean lubricant passageway.
Replace fitting if necessary.
5. Inject grease until you see grease being expelled
from the bearing or bushing areas.
• Use a long pole or bar to dislodge material
from paddles or grille. Pressure in hydraulic
system and paddle spring tension can cause
paddles to kick back if they are jammed.
• When a guard is opened or removed for
servicing, be sure to install or close it before
starting.

HARDWARE SPECIFICATIONS
Note: Unless stated otherwise, hardware is typically:
Hex, Plated GR5 UNC or P8.8 (metric)
TORQUE SPECIFICATIONS
Checking Bolt Torque
The tables below give correct torque values for various bolts
and capscrews. Tighten all bolts to the torques specifi ed in
chart unless otherwise noted. Check the tightness of bolts
periodically, using these bolt torque charts as a guide.
Replace hardware with the same strength (Grade/Class) bolt.
• Make sure that all components in the hydraulic
system are kept in good condition and are clean.
• Replace any worn, cut, abraded, fl attened or
crimped hoses and metal lines.
• Do not attempt any makeshift repairs to the
hydraulic lines, fi ttings or hoses by using tape,
clamps or cements. The hydraulic system operates
under extremely high-pressure. Such repairs will
fail suddenly and create a hazardous and unsafe
condition.
• 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.
• If injured by a concentrated high-pressure stream of
hydraulic fl uid, seek medical attention immediately.
Serious infection or toxic reaction can develop from
hydraulic fl uid piercing the skin surface.
• Before applying pressure to the system, make sure
all components are tight and that lines, hoses and
couplings are not damaged.
HYDRAULIC HOSE SPECIFICATIONS
Note: Unless otherwise stated, Hydraulic Hoses are
either 3/8 or 1/2 with 3/4 JIC female swivel ends.
The following tips are to help you identify some possible
problem areas in the installation of hydraulic hoses.
1. Ensure hoses are not twisted during installation as
this may weaken the hose. Also, the pressure in a
twisted hose may loosen fi ttings or connections.
2. Allow suffi cient bend radius in hoses when installing
to prevent lines from collapsing and fl ow becoming
restricted.
3. When installing hoses in an area of movement or
fl exing, allow enough free length for motion and to
ensure fi tting connections are not stressed.
4. Ensure hoses are properly clamped and secured in
position after routing is complete to provide a cleaner
installation and prevent possible damage or hazards.

Note: A DASH size refers to a diameter of a hose (inside)
or of a tube (outside) measured in 1/16” increments.
For example, a Hose specifi ed as dash 8 or -8 would
have an inside diameter of 8/16” or 1/2”.
Alternatively, a Tube specifi ed as dash 8 or -8 would
have an outside diameter of 8/16” or 1/2”.
ORB (O-Ring Boss)
Male ORB fi ttings have straight UNF threads, a sealing face
and an O-ring. The female fi ttings are generally found in the
ports of machines and feature straight threads, a machined
surface, and a chamfer to accept the O-ring. Sealing is
achieved through the compression of the male O-ring
against the chamfered sealing face of the female fi tting.
