• Keep hands and body away from pressurized lines.
Use paper or cardboard, not body parts to check
for leaks. Wear safety goggles. Hydraulic fluid
under pressure can easily penetrate skin and will
cause serious injury or death.
• Make sure that all operating and service personnel
know that in the event hydraulic fluid penetrates
skin, it must be surgically removed as soon as
possible by a doctor familiar with this form of
injury, or gangrene, serious injury or death will
result. CONTACT A PHYSICIAN
IMMEDIATELY IF FLUID ENTERS SKIN
OR EYES. DO NOT DELAY.
• Do not allow children or untrained persons to
operate equipment.
PREPARATION
• Air in hydraulic systems can cause erratic operation
and allows loads or equipment components to drop
unexpectedly. Before operating or allowing
anyone to approach the equipment, purge any air
in the system by operating all hydraulic functions
several times after connecting equipment,
connecting hoses, or doing any hydraulic
maintenance.
• Check that all hardware is tight and properly
installed. always tighten to torque chart
specifications.
• Before starting tractor, check all equipment driveline
guards for damage and make sure they rotate freely
on all drivelines. Replace any damaged guards. If
guards do not rotate freely on drivelines, repair and
replace bearings before operating.
• Make sure driveline is correct length to prevent
bottoming out or pulling apart during the full lift
range of the hitch.
• Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
splined groove.
•After connecting hoses, check that all control lever
positions function as instructed in the Operator’s
Manual. Do not operate until control lever and
equipment movements are correct.
• Make sure all hydraulic hoses, fittings, and valves
are in good condition and not leaking before starting
power unit or using equipment. Check and route
hoses carefully to prevent damage. Hoses must
not be twisted, bent sharply, kinked, frayed,
pinched, or come into contact with any moving
parts. Operate moveable components through full
operational range to check clearances. Replace any
damaged hoses immediately.
Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing and head.
•Ensure implement is properly attached, adjusted
and in good operating condition.
•Power unit must be equipped with ROPS (Roll Over
Protection Structure) or ROPS CAB and seat belt/
operator restraint. Keep seatbelt/operator restraint
securely fastened/engaged. Falling off power unit
can result in death from being run over or crushed.
Keep ROPS systems in “locked up” position at all
times.
Remove accumulated debris from this equipment,
tractor, and engine to avoid fire hazard.
A minimum 20% of tractor and equipment weight
must be on tractor fron wheels with attachments
in “transport” position. Without this weight,
tractor could tip over causing personal injury or
death. The weight may be attained with a loader,
front wheel weights, ballast intires, or front tractor
weights. When attaining the minimum 20%
weight on the front wheels you must not exceed
the Roll Over Protection Structure (ROPS) weight
certification. Weigh the tractor and equipment.
Do not estimate.
• Ensure all safety decals are installed. Replace if
damaged. (See Safety Decals section for location.)
• Ensure shields and guards are properly installed and
in good condition. Replace if damaged.

and attach to the PTO shaft at the rear of the tractor.
Wrap driveline storage chain around hitch tube and
secure it so that it will not contact PTO driveline.
OPERATION

13PN-P970620 (03/2005)
IMPORTANT
•If the PTO is too long, severe PTO and gearbox
damage is possible when hooking up the PTO
from the power rake to the tractor. The front
PTO is long enough to fit a variety of tractors.
It is possible that the front PTO will need to
be cut. There will be NO benefit by cutting
only one telescoping section. Both sections of
the PTO must be cut. DO NOT FORCE THE
PTO TO FIT.
•WARRANTY IS VOID IF THE PTO IS
TOO LONG, resulting in gearbox, PTO, yoke,
or cross bearing damage.
The PTO, when attached to the tractor and gearbox,
must not extend so there is less than five inches of
overlap within the PTO.
Attach the two hydraulic lines on the rake to the two
female hydraulic couplers on the tractor. The hydraulic
hose ends on the power rake are ISO male couplers,
which are compatible with newer tractors.
Raise jackstand and secure in operating position.
IMPORTANT
•• Always clean connector ends prior to attaching.
Dirt could contaminate hydraulic fluid and
damage the hydraulic system.
POWER RAKE FUNCTION
The tractor PTO drives the two rollers. The lower
roller digs in the ground pulling up rocks and debris.
The clean soil goes between the rollers and the rock,
and the debris works to the side in a windrow. The
scarifier also brings up debris from below the ground
and loosens the soil so the rollers can function more
efficiently.
Maximum safe PTO operating speed is 540 RPM.
PRE-OPERATION CHECK LIST
___ Review and follow all safety rules and safety decal
instructions on pages 6 through 11.
___ Check that all safety decals are installed and in
good condition. Replace if damaged.
___ Check that all shields and guards are properly
installed and in good condition. Replace if
damaged.
___ Check that all hardware and cotter pins are
properly installed and secured.
___ Check that equipment is properly and securely
attached to tractor.
___ Make sure driveline spring-activated locking pin
or collar slides freely and is seated firmly in
tractor PTO spline groove.
___ Before starting tractor, check all equipment
driving guards for damage and make sure they
rotate freely on all drivelines. Replace any
damaged guards. If guards do not rotate freely
on drivelines, repair and replace bearings before
operating.
___ Do not allow riders.
___ Check for and keep all bystanders away from
equipment working area.
___ Make sure gearbox is filled to the correct level
with high quality 80W-90 gear oil.
___ Check all lubrication points and grease as
instructed in “Maintenance, Lubrication”
information.
___ Check that all hydraulic hoses and fittings are
in good condition and not leaking before starting
tractor. Check that hoses are not twisted, bent
sharply, kinked, frayed, or pulled tight. Replace
any damaged hoses immediately.
___ Make sure tractor ROPS or ROPS CAB and seat
belt are in good condition. Keep seat belt
securely fastened during operation.
___ Check tire pressure and service if necessary.
OPERATION

14 PN-P970620 (03/2005)
With the power rake angle cylinder connected to a
tractor hydraulic control valve, move tractor control
valve to select the desired angle. Return the tractor
control to neutral to maintain the selected angle.
The hydraulics allow the operator to change the angle
of the rake by just moving the hydraulic control on the
tractor. It also allows the operator to raise or lower
the scarifier from the tractor seat by just moving the
same hydraulic control lever.
Both of these functions are possible using the manual
directional valve mounted on the power rake. The bi-
angle function can be activated by placing the handle
in its staight forward position. To allow actuation of
the scarifier cylinders, rotate the handle 90 degrees.
Power Rollers
The roller should be level with the ground. To level
the rake from side to side, adjust one of the tractor 3-
point lower lift arms.
The power rake should be level front to back. Level
the rake using the tractor 3-point top link, the 3-point
lift arms, or the gauge wheels.
To allow the roller to penetrate deeper into the ground,
loosen the handle and raise the gauge wheels. To
achieve the opposite, lower the gauge wheels.
Be sure to check the air pressure in each tire regularly
so that an even, consistent grade will be maintained.
The normal gap between the rollers for average
conditions is about 1 inch. This gap can be adjusted
either wider or narrower by turning the adjusting nuts
on rods at each end of the roller. A wider opening will
allow more dirt and rock to pass through the rollers.
For finer raking, reduce the gap between the rollers.
(Be careful not to let the two rollers hit.) The gap
between the rollers should be the same all the way
across. Roller adjustment is shown in Figure 2, pg.16.
Scarifier-Tines
The function of the tines is to loosen rock and debris
below the ground surface. They should be allowed to
run in the dirt 2 to 3 inches deep. Tine shovels are
reversible and replaceable when worn.
OPERATING INSTRUCTIONS
Read and understand the power rake and tractor
Operator’s Manuals before operating the power rake.
Failure to do so may result in death, serious personal
injury, or property damage.
Never raise the power rake more than a few inches off
the ground when traveling from job site to job site.
Shut off the engine, set brake, remove key, and remove
seat belt. Dismount the tractor.
WARNING
•Look down and to the rear and make sure area
is clear before operating in reverse.
•Never direct discharge toward people, animals,
or property.
•Only engage power when equipment is at ground
operating level. Always disengage power when
equipment is raised off the ground.
Start-Up Sequence
WARNING
•Only engage power when equipment is at ground
operating level. Always disengage power when
equipment is raised off the ground.
Start tractor engine.
Lower power rake slowly to the ground.
Engage tractor PTO.
Increase engine rpm to give desired rpm at the roller.
Normal operating speed must not exceed 540 rpm. If
operating in heavy rock, reduce the speed slightly.
Move the tractor forward. Select a slow tractor speed
and increase slightly until operation is satisfactory.
Ground Speed
Ground speed should be between 3 mph and 5 mph
under normal conditions. In heavy rock, reduce the
ground speed to 1 mph to 3 mph.
Power Rake Angle Adjustment and Scarifier
Control
The power rake may be angled up to 15 degrees left or
right for placing material in a windrow.
OPERATION

15PN-P970620 (03/2005)
Operating Depth
When power raking, the depth will determine how
much dirt is carried ahead of the rollers. The ideal
depth will vary with conditions and can be anywhere
from skimming the surface to about 3 inches deep.
See instructions in “Power Rollers” pg. 14, to set roller
depth.
When making the first windrow, the level of dirt may
be halfway up on the top roller. When moving the
windrow two or three times, the level of the dirt may
be to the top of the top roller. However, try to prevent
material from flowing over the top.
The power rake allows fast raking of large areas of
ground by being able to move windrows several times.
Of course, the volume or density of the material being
raked will dictate how many times a windrow can be
moved.
Soil can be removed from the windrow by moving it
back and forth a few times onto the clean area. If dirt
clods are a problem, running the tractor tire over the
windrow and then moving it a final time will help to
break up and cut down on dirt clods.
Operator Production
Successful operation of the power rake will come with
operator experience. The rake’s performance also
depends on the type and size of the tractor it’s mounted
on.
An operator that masters the technique of adjusting
the angle of attack of the roller against the soil will
also find ideal settings under various conditions to give
the desired results.
IMPORTANT
•Do not drop power rake to the ground with the
roller turning. Sudden high-speed jolts
multiply stress to the driveline and can cause
extreme damage.
Shutting Down
Stop equipment.
Lower the lift arms and power rake to the ground.
Purge any air in the system. Hydraulic system leak-
down, hydraulic system failures, mechanical failures,
or movement of control levers can cause equipment to
drop or rotate unexpectedly.
Shut off engine, set brake, remove key, and remove
seat belt before leaving the tractor operator’s seat.
WARNING
•Do not disconnect hydraulic lines until all
system pressure is relieved. Lower unit to
ground, stop engine, and operate all hydraulic
control levers.
REMOVING POWER RAKE FROM TRACTOR
WARNING
•Do not allow other people in the area when
operating, attaching, removing, assembling, or

OPERATION

17PN-P970620 (03/2005)
The information in this section is written for operators
who possess basic mechanical skills. Should you need
help, your dealer has trained service technicians
available. For your protection, read and follow all
safety information in this manual.
Regular preventive maintenance and immediate repair
of broken or worn parts will ensure maximum
efficiency and long life.
Because of the nature of the jobs the power rake does,
such as site preparation and rock raking, the power
rake is constantly vibrating and shaking. Parts may
loosen up as it is used. One of the most important
functions an operator can perform is observing and
inspecting the equipment for loose or worn parts to
prevent further damage or excessive downtime.
WARNING
•Never go underneath equipment lowered to the
ground or raised. Never place any part of the
body underneath equipment or between
moveable parts even when the engine has been
turned off. Hydraulic system leak-down,
hydraulic system failures, mechanical failures,
or movement of control levers can cause
equipment to drop or rotate unexpectedly and
cause severe injury or death.
•Service work does not require going
underneath equipment.
•Read Operator’s Manual for service
instructions or have done by a qualified
dealer.
•Before dismounting tractor or performing any
service or maintenance, disengage power to
implement, lower the 3-point hitch and all
raised components to the ground, operate valve
levers to release any hydraulic pressure, stop
engine, set parking brake, remove key, and
unfasten seat belt.
•Do not allow other people in the area when
operating, attaching, removing, assembling, or
servicing equipment.
•Never perform service or maintenance with
engine running.
•Ensure shields and guards are properly installed
and in good condition. Replace if damaged.
•Keep hands and body away from pressurized
lines. Use paper or cardboard, not body parts
to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily
penetrate skin and will cause serious injury or
death.
WARNING
•Make sure that all operating and service
personnel know that in the event hydraulic fluid
penetrates skin, it must be surgically removed
as soon as possible by a doctor familiar with
this form of injury, or gangrene, serious injury,
or death will result. CONTACT A
PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
•Make sure all hydraulic hoses, fittings, and
valves are in good condition and not leaking
before starting power unit or using equipment.
Check and route hoses carefully to prevent
damage. Hoses must not be twisted, bent
sharply, kinked, frayed, pinched, or come into
contact with any moving parts. Operate
moveable components through full operational
range to check clearances. Replace any
damaged hoses immediately.
CAUTION
•Your dealer can supply original equipment
hydraulic accessories and repair parts.
Substitute parts may not meet original
equipment specifications and may be
dangerous.
•Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes, and protective
equipment for eyes, hair, hand, hearing, and
head.
WARNING
•Do not modify or alter, or permit anyone else
to modify or alter, the equipment or any of its
components in any way.
•Ensure all safety decals are installed. Replace
if damaged. (See “Safety Decals” section for
location.)
MAINTENANCE

18 PN-P970620 (03/2005)
DAILY MAINTENANCE
When operating the power rake, check the tractor
hydraulic system to be sure the level of hydraulic oil
is adequate. If necessary, add hydraulic oil as
recommended in your tractor operator’s manual.
Repair hydraulic oil leaks promptly to avoid loss of
oil and serious personal injury from escaping oil.
After every 10 hours of operation, check all hardware
and tighten where required.
WEEKLY MAINTENANCE
Lightly lubricate bearing at each end of the rollers (1-2
pumps). Use a lithium grease of #2 consistency with a
MOLY (molybdenum disulfide) additive for all locations.
Be sure to clean fittings thoroughly before attaching
grease gun. See Figure 3.
Lubricate all pivot points. Use a lithium grease of #2
consistency with a MOLY (molybdenum disulfide)
additive for all locations. Be sure to clean fittings
thoroughly before attaching grease gun. See Figure 3.
Check tire pressure. Maintain 60 psi cold.
Lubricate driveline universal joints.
MONTHLY MAINTENANCE
Inspect drive chain.
Inspect and clean safety decals. Replace if damaged.
(See “Safety Decals” section for location.)
Check oil level in chain case.
Check gearbox oil level.
QUARTERLY MAINTENANCE
Change oil in chain case and add 1.5 pints of 85W 140
wt. lube.
PRELIMINARY CHECK
The best maintenance is regular preventive checks,
particularly when the machine is new. Check that all
nuts and bolts are tight.
CHAIN MAINTENANCE
The drive chain should be inspected weekly. New
chain has a tendency to stretch, so it is necessary to
check the chain tension to prevent flopping around,
thus causing potential problems.
The adjustment for chain tension is in the chain case.
To tighten the chain, loosen jam nut (#63) and turn the
adjusting bolt (#61) clockwise until the chain is snug.
Let the spring give the desired tension.
NOTE: The tension spring should be compressed to
4-3/4 inches for proper tension.
IMPORTANT
•Replacement chain should be only high quality
original equipment chain for longer life.
When being stored for a long period or at end of season,
change the oil, adding EP 85W 140 wt. oil, and rotate
the roller several times allowing the chain to be coated
with oil, enhancing chain life. Rotate the roller
periodically to maintain lubrication.
SPROCKETS
Sprockets should be checked to be sure slotted hex
nut is tight, the cotter pin is in place, and the sprocket
cannot move on shaft.
PTO DRIVE LINES
Periodically check the yoke on both ends of the front
PTO to the tractor. Make sure the set screws/jam nuts
are tight and the yoke is not moving on the shaft. PTO
shafts and U-joints should be sparingly lubricated
weekly.
GEARBOX
The gearbox is almost maintenance-free, but should
be checked monthly to be sure that the oil level is
maintained at half full. EP 80-90 wt. gear lube is rec-
ommended for use in the gearbox. Oil should be
changed after the first 100 hours or 30 days of operat-
ing. Then, normal change intervals of 1,000 hours or
12 months of operation should be adequate. In the
case of seasonal usage, it is best to change the oil at
the end of the season to remove moisture and corro-
sive contaminants.
It should be noted that the gearbox only exceeds its
thermal capacity when the oil temperature exceeds
200°F.
