Hearing Loss
Prolonged Exposure To Loud Noise May
Cause Permanent Hearing Loss!
Working environments with noise-producing
equipment can cause partial to permanent hearing
loss. We recommend using hearing protection
any time noise levels exceed 80 decibels (dB).
Noise levels over 85 dB, on a long-term basis, can
cause severe hearing loss. Noise levels over 90
dB over a period of time can cause permanent
and even total hearing loss.
Hearing loss from loud noise is cumulative over a
lifetime without hope of natural recovery.
Crush Hazard
The tractor should be equipped with
a Roll Over Protective Structure
(ROPS) and a seat belt. A crushing hazard may
occur if the driver is ejected from the seat while
the tractor is in motion. Fasten the seat belt
whenever the tractor is moving.

6.1 OSHA Training Requirements
The following training requirements have been taken
from Title 29, Code of Federal Regulations Part
1928.57 (a) (6). www.osha.gov.
Operator instructions. At the time of initial
assignment and at least annually thereafter, the
employer shall instruct every employee who
operates an agricultural tractor and implements
in the safe operating practices and servicing of
equipment with which they are or will be involved,
and of any other practices dictated by the work
environment.
WARNING
STOP
Roll Away Hazard
Before leaving the
tractor seat, make sure
the engine is stopped, the transmission is placed
in park, the key is removed, and the parking brake
is set.
The weight of the tractor, plus the wheel
rake, if it rolls onto a person, could cause
serious crushing injury or death.
Crush Hazard
The tractor should be equipped with
a Roll Over Protective Structure
(ROPS) and a seat belt. A crushing hazard could
occur if the driver is ejected from the seat while
the tractor is in motion. Fasten the seat belt
whenever the tractor is moving.
Crush Hazard
Hydraulic or mechanical failure can
allow a wing to drop suddenly without
warning. Do not allow anyone to walk under or
stand near a raised wing when the wing locks are
removed.
SAFETY
INSTRUCTIONS The following safety
instructions are provided to
help prevent injury or limit equipment damage.
THINK
SAFETY! Train Unfamiliar Users
It is the wheel rake owner’s
responsibility to make sure any person using the
wheel rake, especially if it is loaned or rented, has
been thoroughly trained on its proper and safe use.
Be certain only physically-able persons will use
the wheel rake.
Users who have not read and understood all
operating and safety instructions are not qualied
to use the wheel rake.
If the elderly are assisting with the work, their
physical limitations need to be recognized and
accommodated.
Never allow children to operate equipment.
6.2 Attaching to Tractor
Use caution when connecting the wheel rake to the
tractor. The wheel rake should be securely resting
at ground level or setting on blocks. Keep hands
and feet clear of pinch points between the tractor
drawbar and wheel rake hitch.
1. Use the jack to adjust the hitch to the height
of the tractor drawbar. See section 6.3.1 for
instruction on setting hitch clevis.
2. Board the tractor and start the engine. Back the
tractor up to the rake hitch clevis until the holes in
the drawbar and clevis are aligned.
Crush Hazard
Crush hazard between hitch and
implement. Do not allow anyone
to stand between the hitch and implement
during hook-up operations.
3. Turn off the tractor engine and dismount.
4. Insert a 1” hitch pin with retaining clip through the
clevis and drawbar holes and install retaining clip.
Do not use a homemade or shop made pin.
OEM
OEM
Crush Hazard
Unexpected separation of the
implement from the tractor could
cause death or serious injury. Use only an
OEM high strength drawbar pin. Do not use a
homemade or shop made pin.

5. Retract the jack, remove the locking pin, move
the jack to its storage location on the wheel rake
frame, and secure it with the locking pin.
6. Inspect all the hydraulic hoses to ensure they
are in good condition. Route the hydraulic hoses
through the hose rack, make sure the fittings are
clean, and attach to the tractor’s hydraulic ports.
Make sure the hoses are adequately supported
so they cannot come in contact with other parts or
the ground.
7. If installed, lower the kicker wheel.
a. Open the shut off valve.
b. Operate the hydraulics raising and lowering
the wings and kicker wheel in order to remove
any air trapped in the system. It may take
several cycles to remove all of the air. The
kicker wheel should raise and lower with the
wings.
8. Lower the rake wings.
a. Ensure “Rake Arm Position” valves are both in
the unlocked position.
b. Pull on the rope to unlock the safety latches
c. While holding the rope tight, operate the
appropriate valve to lower the wings
6.3 Setting the Wheel Rake
Properly setting the wheel rake is essential for
efficient operation. The adjustments to make before
using are:
6.3.1 Level the Rake
It is very important that the wheel rake is level in the
operating position.
1. If the rake arm is not level, remove the two 5/8”
bolts holding the hitch clevis
2. Using the jack, adjust the tongue up or down so
that the rake arm is level.
3. Re-install the bolts and tighten to the proper
torque.
4. The rake is designed to be level when this edge
is 12” above ground. See sticker for illustration.
5. For really tall drawbar heights, the hitch clevis
can be inverted to gain extra height.

6.3.2 Adjust the Overall Rake Working Width
The overall width can be adjusted to operate the
rake at a steeper angle in heavy crops or at a flatter
angle in light crops and still maintain the desired
windrow width.
1. Using the tractor hydraulics, fold and lock the
wings.
2. Remove the jack from its storage location attach
it to the jack mount on the wing. Make sure to
position the jack foot in the notched bracket.
Install the retaining clip in the jack mount.
3. Remove the clevis pin from the wing arm
adjustment hole.
4. Operate the jack to align the adjustment holes for
the desired width. Refer to section 6.3.7 for rake
specifications.
5. Re-install the clevis pin and its retaining clip in the
wing arm adjustment hole.
6. Remove the jack, and repeat the process for the
other wing arm.
7. When finished, move the jack to its storage
location on the wheel rake frame, and secure it
with the locking pin.
6.3.3 Adjust the Rake Angle
The rake angle can be set to any one of three
available positions.
1. Using the tractor hydraulics, raise the wings until
the rake wheels are off of the ground..
2. Rotate the lock tab, pull out on the pin, and rotate
the lock tab into the upper notch. Refer to section
6.3.7 for rake specifications.
Tip: this is easier to do if you leave the rake arm
up is lifted just high enough that the rake wheels
are not touching the ground
3. Pivot the rake arm to the desired position.

4. Rotate the lock tab, push in the pin, and rotate
the lock tab into the lower notch.
5. Repeat the process for the other wing.
6.3.4 Adjust the Rake Wheel Ground Pressure
Rake wheel ground pressure can be controlled by
adjusting the flotation spring tension to any one of
five settings. Adjust the ground pressure to the least
amount necessary to achieve good raking action.
Excessive rake wheel ground pressure can cause
crop damage, premature rake wheel tine wear, and
broken tines.
1. Using the tractor hydraulics, fold and lock the
wings.
2. Remove the flotation catch pin.
3. Insert the pin into the desired hole to increase or
decrease ground pressure. Replace the lynch pin
retainer.
Note: Using the hole 1 will result in the least
amount of ground pressure. Using the
hole 5 will give the most ground pressure.
4. Repeat the process for the other wing.
6.3.5 Wheel Rake Operation
Begin raking at a low ground speed until you are
familiar and comfortable with the rake. Working
speed is normally 5 to 10 mph, and will vary with
different hay conditions or terrain.
Reduced ground speed may be necessary for hills
or rough terrain.
Raking direction will affect raking efficiency. For
sickle mowed hay, rake in the same direction as
mower travel. For rotary mowed hay, rake in the
opposite direction as mower travel
Most raking problems can be traced to incorrect
speed, incorrect ground pressure, or broken or
missing tines.
Use only enough ground pressure to pick up the
crop material.
NOTICE Raise the rake wheels before
backing the tractor. Backing the
tractor with the tines in contact with the ground will
cause tine breakage.
6.3.6 Single Sided Rake Operation
The rake can be operated with one side only.
This is helpful when raking very thick hay to limit
the windrow size, or when a windrow needs to be
moved to the side or inverted.
To use single side raking, lift the rake arms into the
transport location. In the back of the rake, turn the
valve on the side of the rake you do not want to
use. Turning this valve will keep that rake arm in the
upright/transport location while allowing the other
side to move up and down as normal.
