CONTROL FUNCTIONS
A
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.
Please Take a moment and
familiarize yourself with the
name, location, and function
of these controls so that you
will better understand the safe-
ty and operating instructions
provided in this manual.
Figure 1. Control Locations
A. Blade Angle Control Lever
B. Attachment Lift
A. Blade Angle Control Lever
The blade angle release lever controls a spring-loaded
plate which locks the blade in one of three positions.
Use an abrupt pushing/pulling motion to release the
angling mechanism and move the blade left or right.
Push the angling lever forward fully to lock the blade in
the left position. Pull the lever fully back to lock the
blade in the right position. Move the lever slowly past
center to lock in the centered position.
NOTE: It is easier to change the angle of the blade with
the attachment raised.
B. Attachment Lift
TRACTOR CONTROLS
The attachment lift lever raises and lowers the dozer
blade. To RAISE an attachment, depress the release
button on top of the lever and pull back. To LOWER an
attachment, depress the release button and move the
lever forward.
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.
The back notch suspends the blade for transporting to
and from the worksite. The middle notch is the “float”
position. The front notch applies downward pressure on
the blade. See the Adjustments section for proper blade
adjustment.
• Practice driving in an open area—without doz-
ing—to become accustomed to the unit.

General
Operating Instructions
Checks Before Starting
WARNING
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.
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.
2. Remove any objects from the work area which might
interfere with plowing activity.
Use caution when plowing a snow covered area.
Snow can cover objects such as curbs, drop-offs,
and other obstacles. Be familiar with the area you
are plowing.
3. Adjust the skid shoes to desired height. See Skid
Shoe Adjustment.
4. Make sure all hardware is present and secure.
To prevent an explosion or fire, never store the
tractor with fuel in the tank inside a building
where an ignition source is present.
Engine & Ground Speed Selection
Always run the engine at full throttle.
Set tractor speed to obtain the needed power to move
the material. Operate at a safe speed, depending on
conditions, so that you have complete control of the trac-
tor. Rear wheel weights and chains are recommended
for slippery surfaces.
IMPORTANT NOTE
To prevent damage to the unit, always
raise the dozer blade BEFORE turning or
backing up.
A rear weight carrier is recommended for additional trac-
tion.
DANGER
OPERATING ON SLOPES CAN BE DANGEROUS
Transporting
Never operate on slopes greater than 17.6% (10°)
which is a rise of 3-1/2 feet (106cm) vertically in
10 feet (607cm) horizontally.
For maximum ground clearance, transport the blade to
and from work areas fully raised and angled straight
ahead.
Operate the unit at a slow ground speed when
driving onto slope. Avoid using brakes to control
ground speed.
Starting & Stopping
When operating on slopes that are greater than
15 % (8.5°) but less than 17.6%, use additional
wheel weights or counterweights.
1. Start the tractor engine. Set engine throttle to full.
2. Raise the attachment lift and travel to the work site.
3. Set the angling control to the desired angle.
4. Lower the attachment lift and begin plowing.
5. Raise the plow before backing up.
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.
6. To stop the tractor, set ground speed to neutral and
set the parking brake. Before leaving the seat, stop
the engine, set the parking brake, remove the key,
and wait for all moving parts to stop.
For additional traction, tire chains and a weight
box can be added. Maximum weight added to
tractor should not exceed 35 lbs. per wheel and
100 additional lbs. in weight box.

General Operating Instructions
Changing Angle of the Blade:
Snow Plowing Tips
See Figure 1 for location of Controls.
• Determine the best snow removal pattern before
beginning.
NOTE: It is easier to change the angle of the blade with
the attachment raised.
• Plan the pattern so that you avoid pushing snow onto
cleared areas.
1. Raise the attachment lift.
• When land contour permits, it is best to travel in the
longest direction to minimize turning.
2. Use an abrupt pushing/pulling motion to release the
angling mechanism and move the blade left or right.
Push the angling lever forward fully to lock the blade
in the left position. Pull the lever fully back to lock the
blade in the right position. Move the lever slowly over
center to lock in the centered position.
• 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 nec-
essary to clear less than the full width of the dozer
blade or reduce ground speed.
Dozing Tips
• 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 plowing to
build up.
• 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 nec-
essary to clear less than the full width of the dozer
blade or reduce ground speed.
• If pushing snow past the edges of driveways or side-
walks, 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 damag-
ing the grass.
• Spinning tires with tire chains can leave unsightly
marks or permanent damage to asphalt or concrete
driveways or sidewalks. Avoid sudden stops or
starts.
• 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 down-
hill, and set the blade angle so that the plowed mater-
ial is moving downhill as it leaves the blade.
Storage
Off-Season Storage
IMPORTANT NOTE
Refer to Tractor Operator’s Manual for
important information concerning safely
storing your tractor.
1. Remove dozer blade and hitch from the tractor.
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.
Daily Storage
4. Lubricate the dozer blade.
1. Allow tractor engine to cool before storing in any
enclosure.
5. Store the dozer blade and hitch in a dry place.
2. After dozing or plowing 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.

Maintenance
WARNING
Lubricate Dozer Blade
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.
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 lubricat-
ed 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.
Schedule For Normal Care
Care Required
Schedule
Clean debris from
dozer blade.
After each use.
Lubricate dozer blade.
Every 10 hours or at
least once a year.

Adjustments
Skid Shoe Adjustment
Slotted holes are provided to permit adjustment of the
shoe assemblies for raising and lowering the blade to
various working heights (see Figure 3).
When cleaning snow from gravel or earth drives or
walks, the shoe assemblies should be lowered fully to
prevent blade contact with gravel or ground. When
cleaning smooth hard surfaces like concrete, the shoe
assemblies are normally placed fully up to allow the
blade to scrape the surface.
To adjust the skid, raise the blade off the ground and
block with a piece of wood. Loosen the bolts (B, Figure
3) and move the skid shoes (A) up or down to desired
height. Tighten the bolts securely.
Figure 3.
A. Skid Shoes
B. Bolts
Spring Tension
See Figure 4. This snow plow/dozer blade is spring
loaded so that when the blade strikes a solid object, the
springs will allow the blade to release as shown, rather
than cause damage. The blade will go back to its original
position after object is cleared.
Figure 4. Dozer Blade “Released”
See Figure 5. To adjust spring tension hold rear nut (B)
and loosen front nut (E). Tighten rear nut (B) to increase
spring tension, or loosen to decrease tension.
For initial adjustment, tighten nut (B) on each eyebolt
enough to expose about 3/4" (19mm) of thread. Tighten
front nut (E) against rear nut (B) to lock adjustment in
place.

Adjustments
Lift Rod Adjustment
A
B
The lift lever can be placed in one of three notches and
is held in position by the lever latch. (see Figure 7).
When the lever latch is placed in notch 1 the lift lever
should be applying downward pressure on the attach-
ment. In position 2, the “float” position, the attachment
should experience negligible upward or downward pres-
sure. Position 3 should raise the attachment approxi-
mately 6“ above the ground.
C
D
E
NOTE: Always adjust the lift height before and after
adjusting the downward pressure.
LIFT HEIGHT ADJUSTMENT
1. Place the lever latch in notch 3 (see Figure 7). The
snowthrower should be approximately 6” off the
ground. If not, go to step 2.
Figure 6. Adjusting Lift Rod

D. Rear Set Collar
E. Spring Clip
2. Lower the attachment and adjust the front set collar
(A, Figure 7) to achieve the correct lift height.
DOWNWARD PRESSURE ADJUSTMENT
Notch 1
IMPORTANT NOTE
Notch 2
Notch 3
DO NOT OVER-COMPRESS THE SPRINGS.
In addition to providing downward pressure,
the springs are an elastic medium that
absorbs shocks caused by bumps and
cracks in ground surfaces. Over-compress-
ing the springs defeats this and may cause
damage to the unit.
1. Move the lever latch from notch 2 to notch 1 (See
Figure 7).
2. The spring (C, Figure 6) should be slightly com-
pressed applying downward pressure to the
snowthrower. If not, adjust the rear set collar (D,
Figure 6) to achieve the desired amount of downward
force. Do not over-compress the lift rod spring.
