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.
TO THE NEW OPERATOR OR OWNER
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.

Preparation
Although there are no operational restrictions on
the Rock Picker when it is new, there are some
mechanical checks that must be done to ensure
the long term integrity of the unit. When using the
machine for the first time, follow this procedure:
It is extremely important to follow
all of the Break-In procedures especially those
listed in the “Before using” section below to
avoid damage:
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.
After operating for 8 hours:
1. Repeat Step B.
2. Go to the service schedule as outlined in the
“Service & Maintenance” section.
BREAK-IN
OPERATING SAFETY
1. Read and understand the Operator’s Manual
and all safety signs before using.
2. Lower grille and hopper box, stop 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.
3. Keep hands, feet, hair and clothing away from
all moving and/or rotating parts.
4. Do not allow riders on the Rock Picker or tractor
during operation or transporting.
5. Keep all shields and guards in place when
operating.
6. Clear the area of all bystanders, especially
children, before starting.
7. Do not operate machine or raise hopper box on
steep side hills or slopes.
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.

-7-
142922 - Signature 6000/7200 (16-August-2017)
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.
TRACTOR PREPARATION
PTO Models
6. The drawbar pin to PTO shaft end dimension
should be 14 in. (540 PTO).
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.

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.
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.

-8-
142922 - Signature 6000/7200 (16-August-2017)

mechanical retainer such as a Klik pin.
Install the retainer.
7. Install a safety chain between the tractor
drawbar and the hitch pole.
Preparation
HOOK-UP / UNHOOKING
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.
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
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
Turn jack sideways
for field position
Check that height is at
least 6” for adequate
clearance on hills
Ensure hitchpole
is parallel to ground,
adjust with jack.
Adjust pin in
hitch clevis to
set pole height.
Always park on a level surface clear of debris
and obstacles.

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.

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.
Refer to these operational hints before starting:
1. Material size:
The machine was designed
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.
OPERATING
Operation
1-3/4” to 24”
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.
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)
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.
Operation
b. Dumping: The hopper box is
unloaded by extending the
unloading
cylinders on
the box.
• 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.
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.
Ensure no obstructions under
grill or near lift bracket areas.

142922 - Signature 6000/7200 (16-August-2017)
Operation
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.
• 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.
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.
WARNING:
Rocks can ricochet
off to the side.
Keep Bystanders
Away!
WARNING:
Turn to the left to
keep yourself out of
the path of potential
flying rocks.

during operation.
Grille raises too slowly.
Loaded box will not lift
for dumping.
Oil accumulation on
cylinder shaft.
Excessive picking of
dirt.
Excessive rock pile-up
at bottom of grille.
Paddle teeth contact
grille teeth.
CAUSE
Tractor hydraulic leak.
Damaged hose or loose
fittings.
Hydraulic cylinder leak.
Hydraulic pressure from
tractor too low.
Restriction in hose.
External hydraulic leak.
Hydraulic cylinder leak.
Oil bypassing seals.
Grille set to low.
Reel speed too slow in
relation to forward
travel.
Worn reel springs or
inadequate spring
tension.
Excessive torque limiter
slippage (PTO models).
Reel misaligned.
Bent teeth.
SOLUTION
To verify, raise grille, disconnect at tractor and observe if grille
creeps down. If not, repair tractor hydraulics.
Search for leaks with a piece of paper (not by hand). Repair as
necessary.
Replace seals or damaged components.
Check pressure, should be 1500-2500 psi.
Disconnect & blow out lines with compressed air.
Repair as needed.
Replace seals or damaged components.
Seal manufacturer advises that small amounts of oil getting past
seals is desirable. If problem becomes excessive, replace seals.
Maintain grille just skimming ground.

Service & Maintenance
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.
• 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.
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.
FLUIDS AND LUBRICANTS
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.
