PROTECT AGAINST FLYING DEBRIS
Always wear proper safety glasses, goggles, or a face shield when driving
pins in or out or when any operation causes dust, ying debris, or any other
hazardous material.
LOWER OR SUPPORT RAISED EQUIPMENT
Do not work under raised 3 point lift arms without supporting them. Do not
use support material made of concrete blocks, logs, buckets, barrels, or any
other material that could suddenly collapse or shift positions. Make sure
support material is solid, not decayed, warped, twisted, or tapered. Lower lift
arms to ground level or onto blocks. Lower lift arms and attachments to the
ground before leaving the cab or operator’s station.
USE CARE WITH HYDRAULIC FLUID PRESSURE
Hydraulic uid pressure can penetrate the skin and cause serious injury or
death. Hydraulic leaks under pressure may not be visible. Before connecting
or disconnecting hydraulic hoses, read your prime movers operator’s manual
for detailed instructions on connecting and disconnecting hydraulic hoses or
ttings.
Keep unprotected body parts, such as face, eyes, and arms as far away as
possible from a suspected leak. Flesh injected with hydraulic uid may de
velop gangrene or other permanent disabilities.
If injured by injected uid, see a doctor at once. If your doctor is not
familiar with this type of injury, ask him to research immediately to deter-
mine proper treatment.
Wear safety glasses, protective clothing, and use a sound piece of card
board or wood when searching for hydraulic leaks. DO NOT USE YOUR

EQUIPMENT SAFETY PRECAUTIONS
Safety is a primary concern in the design and manufacture of our products.
Unfortunately, our efforts to provide safe equipment can be wiped out by a
single careless act of an operator. In addition, to the design and conguration
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. The
designed and tested safety of this equipment depends on it being operated
within the limitations as explained in this manual.
INITIAL SET-UP AND SYSTEMS CHECK
Always check with your prime mover manual or dealer for counter weight
ballast that may be required for machine stability.
Air in hydraulic systems can cause erratic operation and allows loads or
equipment components to drop unexpectedly.
Before operating equipment purge any air in the system by engaging all
hydraulic functions.
Check that all control lever positions function as instructed in the
Operator’s Manual. Do not operate until control lever and equipment

and not leaking before starting power unit. Check and route hoses care-
fully 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 damaged hoses immediately.
Ensure implement is properly attached, adjusted, and in good condition.
Tractor must be equipped with ROPS and seat belt/operator restraint.
Keep seat belt/operator restraint securely fastened/engaged. Falling off
tractor can result in death from being run over or crushed. Keep ROPS
systems in place at all times.
SAFELY OPERATE EQUIPMENT
Improper operation can cause the machine to tip or roll over and cause injury
or death.
Keep tractor lift arms and attachment as low as possible.
Turn on level ground.
Go up and down slopes, not across them.
Keep the heavy end of the machine uphill.
Only engage power when equipment is at ground level. Always disengage
power when equipment is raised off the ground.
Do not disconnect hydraulic lines until all system pressure is relieved.
Never go underneath equipment lowered to the ground or raised.
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.
Never direct discharge toward people, animals, or property.
Do not operate equipment while under the inuence of alcohol or drugs.
Operate only in the daylight or good articial lighting.
Always comply with all state and local lighting and marking requirements.
Ensure equipment is properly attached, adjusted and in good operating
condition.
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
rmly in tractor PTO splined groove.
A minimum 20% of tractor and equipment weight must be on tractor front
wheels with attachments in “transport” position. Without this weight, tractor
could tip over causing personal injury or death. The weight may be at-
tained with a loader, front wheel weights, ballast in tires, or front tractor
weights. When attaining wheels, you must not exceed the Roll Over Pro-
tection Structure (ROPS) weight certication. Weigh the tractor and equip-
ment. Do not estimate.

MODEL T6 HARLEY POWER BOX RAKE® 13
OPERATIONAL PROCEDURE
POWER RAKE FUNCTION
The tractor PTO drives the roller, which digs into the ground, cultivating and pulling up rocks,
roots, and debris. The clean soil goes between the roller and barrier while the rocks, roots,
and debris work to the side in a windrow.
With the endplates mounted in the working position and the rake straight (endplates parallel
with tractor tires), material can be moved along, lling in the low spots.
Maximum safe PTO operating speed is 540 rpm.
Before using your new Harley Power Box Rake, the slip clutch assembly must be in RUN-IN.
See CLUTCH in the maintenance section, page 20, for the RUN-IN procedure. After you have
completed the RUN-IN of the clutch, return to the operating instructions and proceed with start-
up. Failure to run the clutch in could result in pre-mature drive line failure and warranty will be
voided.
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 ex-
ceed 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 and 5 mph under normal conditions. In heavy rock, reduce
the ground speed to 1 to 3 mph.
Power Rake Angle Adjustment
The power rake may be angled up to 15 degrees left or right for placing material in a windrow.
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.
Power Roller
The roller should be level with the ground. To level 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.

14 MODEL T6 HARLEY POWER BOX RAKE®
OPERATIONAL PROCEDURE
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.
Barrier
The normal gap between the roller and barrier for average conditions is about 1-1/4”. This gap
can be adjusted by rotating the barrier and pinning in desired position. A wider opening will allow
more dirt and rock to pass through, allowing wet soil to dry for nal raking. For ner raking, reduce
the gap. Be careful not to let roller hit barrier. The gap should be the same all the way across.
Barrier adjustment is shown in Figure 2 (page 17).
OPERATING DEPTH
When power raking, the depth will determine how much dirt is carried ahead of the roller. The
ideal depth will vary with conditions and can be anywhere from skimming the surface to about 3
inches deep. See instructions in “Power Roller” on page 13 to set roller depth.
When making the rst windrow, the level of dirt may be halfway up on the barrier. When moving
the windrow two or three times, the level of the dirt may be to the top of the barrier. However, try
to prevent material from owing 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 of rocks 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 nal time will help to break up and cut down on dirt clods.
Endplates
The function of the endplates is to contain the material in front of the roller while the clean material
passes between the roller and barrier.
With the endplates mounted in the operating position and the rake straight (endplates parallel
with tractor tires), material can be moved along, lling in the low spots.
By decreasing the gap between the roller and barrier, more material can be pulled along. Barrier
adjustment is shown in Figure 2 (page 17).
When not using the endplates for operation, they can be placed in “storage” position, see Figure
2 (page 17).
Make sure the disconnected power rake is stored on a hard, level surface. Use the endplates
mounted on attachment side of rake to ensure stability.

MODEL T6 HARLEY POWER BOX RAKE® 15
OPERATIONAL PROCEDURE
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 nd ideal settings under various conditions to give the desired results.
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.
APPLICATION TECHNIQUES
The power rake is capable of many applications. The following are some of the common
applications.
See Figure 2 (page 17) for adjustment locations.
Pulverizing Topsoil
For breaking up compacted soil or conditioning hardened baseball diamonds, the 3-point top
link is set in the “lock-out” positions so that down pressure can be exerted on the tooth roller.
The top link is shortened to take the guide wheels off the ground so only the toothed roller is in
contact with the ground. The rake can be straight or angled, with the barrier opened up to allow
material to ow over the roller.
Debris Removal
Once the surface has been loosened, the process of removing debris can begin. The 3-point hitch
top link is mounted in the “oat” position holes. This allows the rake to begin the early stages of
the nal grading process. The 3-point hitch is lowered until the guide wheels control the depth
of the toothed roller. The rake can be angled at this time for windrowing debris or the rake can
be set straight with both endplates installed to collect debris. Tractor travel speed should be
increased for this process.
Finish Grading
For this operation, set the tractor top link in the “oat” position and mount both endplates in the
“forward” position. The rake is tilted forward until the teeth of the toothed roller are barely touching
the soil. Tractor speed can be increased for this operation, the idea being to collect material from
the high spots and leave it in the low areas.
Spreading Fill and Topsoil
Start with tractor top link in “xed” position and rake tilted on gauge wheels, since depth of cut
is not the objective. Endplates can be installed and the windrow angle set as needed to control
the material movement.
Changing Grade
Grade modication can be accomplished during nish grading by angling the rake to collect and
windrow the maximum amount of material toward targeted areas. With the ex model, grade
changes can be made by raising one gauge wheel and lowering the opposite.
NOTICE

16 MODEL T6 HARLEY POWER BOX RAKE®
OPERATIONAL PROCEDURE
WARNING
CAUTION
Thatching Existing Grass Areas
This procedure is done with the 3-point top link in the “lock-out” position so accurate depth control
can be maintained. The top link should be lengthened to support the rake on the gauge wheels
and toothed roller raised so teeth are just grazing the surface. Select and maintain a slow travel
speed.
Shutting Down
Stop equipment.
Lower the lift arms and power rake to the ground.
Purge any air in the system. Hydraulic system leakdown, 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.

MAINTENANCE
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 protec-
tion, read and follow all safety information in this manual.
Regular preventive maintenance and immediate repair of broken or worn parts will ensure
maximum efciency and long life.
Because of the nature of the jobs the power rake does, such as site preparation and rock rak-
ing, 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 equip-
ment for loose or worn parts to prevent further damage or excessive downtime.

MODEL T6 HARLEY POWER BOX RAKE® 19
CHAIN MAINTENANCE
The drive chain should be inspected monthly. New chain has a tendency to stretch, so it is nec-
essary to check the chain tension to prevent opping around, thus causing potential problems.
Chain tension is preset with the extension spring. If the chain becomes excessively loose, it
may be necessary to remove one link (two pitches). If unable to reassemble, add an offset link
to lengthen the chain.
 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 #00 uid gear
grease, and rotate the roller several times allowing the chain to be coated with lubricant, en-
hancing chain life. Rotate the roller periodically to maintain lubrication.
PTO DRIVE LINES
Periodically check the yokes on both ends of the front and side PTO’s. 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.
SPROCKETS
Sprockets should be checked to be sure slotted hex nut or hex bolt is tight, the cotter pin is in
place, and the sprocket cannot move on shaft.
QUALIFIED TECHNICIAN MAINTENANCE
GEARBOX
The gearbox is almost maintenance-free, but should be checked quarterly to be sure that the
oil level is maintained at half full. EP 80-90 wt. gear lube is recommended for use in the gear-
box. Oil should be changed after the rst 100 hours or 30 days of operating. Then, normal
change 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 corrosive contaminants.
It should be noted that the gearbox only exceeds its thermal capacity when the oil temperature
exceeds 200°F.
BEARINGS
Highest quality bearings are used on the power rake. Only triple-seal bearings are used on the
roller which operates down in the dirt. Lubrication of the bearings will vary considerably with
conditions. As a rule, bearings should be under-lubricated rather than over-lubricated. Over-lu-
brication can cause seals to blow out.
 Replacementbearingsshouldbeonlyhighqualityoriginalequipment 
bearings for longer life.
Install new complete bearing housing if needed or just replace the bearing insert. The shafts
should be straight, free of burrs, and up to size. If shaft is worn, replace or have the shaft built
up to standard prior to completing assembly.
