Features & Controls
TRACTOR CONTROLS
Before you begin operating the tractor with the dozer
blade attachment, make certain you have:
• Read and understood the instructions in the
tractor Operator’s Manual.
• Become thoroughly familiar with all of the
tractor controls and their operation, including
how to safely and properly start and stop the
unit.
• Practiced driving in an open area—without
dozing—to become accustomed to the unit.
A. Angling Control Lever
The angling control lever is used to change the angle of
the dozer blade.
While the engine is running, moving the lever forward
rotates the blade counterclockwise. Moving the lever
back rotates the blade clockwise.
B. Attachment Lift
The attachment lift pedals (see inset above) raise and
lower attachments such as the dozer blade.
To RAISE an attachment, depress the REAR attachment
lift pedal. To LOWER an attachment, depress the
FRONT attachment lift pedal.
C. Two-Speed Control
The two-speed control (see inset above) allows the operator to switch the transmission into high or low-speeds, and
to disengage the transmission into a NEUTRAL (freewheeling) position.
Select the low-speed for all Dozing work and highspeed for travelling to and from work areas. DO NOT
SHIFT WHILE MOVING. See the Tractor Operator’s
Manual for more details.

Please Take a moment and
familiarize yourself with the
name, location, and function
of these controls so that you
will better understand the safety
and operating instructions provided in this manual.
CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Operating the tractor and dozer require the
combined use of these controls and additional controls whose operation is described in the tractor Operator’s Manual.

Operation
Checks Before Starting
1. Refer to the Maintenance & Adjustments sections of
this manual and perform any needed service. Also,
refer to the tractor Operator’s Manual and perform
any required service.
2. Remove any objects from the work area which might
interfere with dozing activity.
3. Adjust the skid shoes to desired height. See Skid
Shoe Adjustment.
4. Make sure all hardware is present and secure.
Engine & Ground Speed Selection
Always run the engine at full throttle.
Normally, a slow ground speed is best for dozing. The
heavier the material, the slower the recommended
ground speed. When dozing always set the 2-Speed
control to LOW.
Transporting
1. Use the attachment lift to raise the dozer blade.
2. Adjust ground speed according to surface conditions.
Select a slow ground speed when transporting on a
slippery surface.
WARNING
Perform the Safety System Interlock test found in
your tractor Operator’s Manual. If tractor does not
pass the test, do not operate the tractor. See your
authorized dealer. Under no circumstances
should you attempt to defeat the safety system.
Use caution when dozing a snow covered area.
Snow can cover objects such as curbs, drop-offs,
and other obstacles. Be familiar with the area you
are dozing.
To prevent an explosion or fire, never store the
tractor with fuel in the tank inside a building
where an ignition source is present.
Starting & Stopping
1. Start the tractor engine. Set engine throttle to full.
2. Raise the attachment lift and travel to the work site.
3. Stop the tractor and set the Two-Speed control to
LOW.
4. Use the angling control lever to set the blade to the
desired angle.
5. Lower the attachment lift and depress the forward
ground speed pedal to plow.
6. Raise the plow before backing up.
7. To stop the tractor, release the ground speed control
pedals. Before leaving the seat, stop the engine, set
the parking brake, remove the key, and wait for all
moving parts to stop.
DANGER
OPERATING ON SLOPES
CAN BE DANGEROUS
Never operate on slopes greater than 30 percent
(16.7°) which is a rise of three feet vertically in 10
feet horizontally.
Operate the unit at a slow ground speed when
driving onto slope. Avoid using brakes to control
ground speed.
When operating on slopes that are greater than
15 percent (8.5°) but less than 30 percent, use
additional wheel weights or counterweights.
In addition to counterweights, use extra caution
when operating on slopes. Drive UP and DOWN
the slope, never across the face, use caution
when changing directions and DO NOT START
OR STOP ON SLOPE.
RAISE dozer blade
before transporting
or backing up.

Operation
Daily Storage
1. Allow tractor engine to cool before storing in any
enclosure.
2. After dozing jobs are completed, hose or brush down
the blade to remove excess dirt.
3. Lightly oil all pivot points. Coat bare metal surfaces to
prevent corrosion.
IMPORTANT NOTE
Refer to Tractor Operator’s Manual for
important information concerning safely
storing your tractor.
Changing Blade Angle
See Figure 1 on page 3 for location of Controls.
1. Fully raise the attachment lift by depressing the
REAR attachment lift pedal (B, Figure 1).
2. Push the angling control lever (A, Figure 1) forward to
rotate the blade counterclockwise. Pull the lever
back to rotate the blade clockwise.
Dozing Tips
• Determine the best dozing pattern before beginning.
• When land contour permits, it is best to travel in the
longest direction to minimize turning.
• In very deep snow or gravel, it may be necessary to
make the first pass with dozer blade partially raised,
then repeat each pass with the blade lowered to clear
the material left on the surface. Also, it may be necessary to clear less than the full width of the dozer
blade or reduce ground speed.
• When dozing, push the dirt to the desired location,
then drag the blade backwards for final leveling. Pack
down the dirt or gravel by driving the tractor over the
leveled area.
• Use any slight grade to your advantage, doze downhill, and set the blade angle so that the plowed material is moving downhill as it leaves the blade.
Snow Plowing Tips
• Determine the best snow removal pattern before
beginning.
• Plan the pattern so that you avoid pushing snow onto
cleared areas.
• When land contour permits, it is best to travel in the
longest direction to minimize turning.
• In very deep or heavy snow, it may be necessary to
make the first pass with dozer blade partially raised,
then repeat each pass with the blade lowered to clear
the material left on the surface. Also, it may be necessary to clear less than the full width of the dozer
blade or reduce ground speed.
• Snow tends to freeze into solid banks when plowed
off a driveway or other large area. Because of this
you may want to plow snow several feet past the
edge of the drive to allow space for future dozing to
build up.
• If pushing snow past the edges of driveways or sidewalks, be careful not to tear up the grass buried
under snow next to the drive or sidewalk. Lift the
blade several inches off the ground to avoid damaging the grass.
Storage
Off-Season Storage
1. Remove dozer blade from the tractor. Hitch can
remain installed if other front mounted attachments
are to be used.
2. Use water pressure or a brush to thoroughly clean
the dozer blade.
3. Paint, or lightly coat with oil, any area where paint
has been worn or chipped away.
4. Lubricate the dozer blade.
5. Store the dozer blade and hitch in a dry place.

Maintenance
Schedule For Normal Care
Care Required Schedule
Clean debris from After each use.
dozer blade.
Lubricate dozer blade. Every 10 hours or at
least once a year.
Lubricate Dozer Blade
Lubricate the dozer blade as shown in Figure 2. Where
an oil can is shown, wipe the area clean, apply a few
drops of oil (SAE 30), then wipe up drips or spills.
In general, linkage connections and other parts that have
partial rotational or sliding movement should be lubricated periodically with SAE 30 weight oil. Avoid applying
excessive amounts of oil since this may cause a build-up
of dirt around the lubricated area, making subsequent
lubrication more difficult to accomplish.
WARNING
To avoid serious injury, perform maintenance on
the tractor or dozer blade only when the engine is
stopped, parking brake is set and all moving parts
have stopped. Always remove the ignition key
before beginning maintenance or adjustments to
prevent accidental starting of the engine.
When performing service work, support the blade
using wood blocks placed under the scraper bar or
skid shoes.
Never put hands or feet under the dozer blade.
