IDENTIFICATION
CHART
Hardware sizes given in the
illustrations throughout this
manual.
If a washer or nut is identified as
“washer, l/2” or “nut, i/2”, this
means the inside diameter is l/2
inch
If a screw is identified as “screw,
i/2 x 2”, this means the shaft
diameter is l/2 inch and the
shaft of the screw is 2 inches
long. If a screw is identified as
“screw,
l/2 - 16 x 2”, the number
“16” means that the screw has
16 threads per inch.

Accessories
For best performance, it is recommended to use tire chains and two (2) rear wheel weights. A rear-
mounted weight box can also be added for addiiional traction. The maximum weight added to the tractor
should not exceed 35 Ibs./wheel plus 100 additional pounds in the rear weight box.
A Snow Cab is available to protect operator from winter weather.

safety Rules
Read these safety rules and follow them closely. Failure to obey these rules could result in loss of con-
trol of vehicle, severe personal injury to yourself or bystanders, or damage to property or equipment. The
in the text signifies important cautions or warnings which must be followed.
ALL WARNING, CAUTION, and instructional
messages on this attachment and on your
tractor should be carefully read and obeyed. Per-
sonal bodily injury can result when these instruc-
GENERAL
*Read the operators manual carefully. Be thor-
oughly familiar with the controls and proper use of
the equipment. Know how to stop the unit and dis-
engage the controls quickly.
*Never allow children to operate the machine. Do
not allow adults to operate it without proper
instruction.
*Keep the area of operation clear of all persons,
particularly small children and pets.
*Do not carry passengers.
*Make sure:
a. tractor and attachments are in good operating
condition.
b. all safety devices and shields are in place
c. and in good working condition, and
d. all adjustments (skid shoe height, etc.) have
been made.
PREPARATION
*Handle gasoline with care-it is highly flamma-
ble.
a. Use approved gasoline container.
b. Never remove the cap of the fuel tank or add
gasoline to a running or hot engine, or fill the
fuel tank indoors. Wipe up spilled gasoline.
*Do not run the engine indoors. Exhaust fumes are
dangerous.
*Shift into neutral before attempting to start the
engine.
*Wear proper footwear. Do not operate tractor
when barefoot or when wearing open sandals or
canvas shoes.
OPERATION
l Do not allow anyone to use the snow plow/dozer
blade unless they have been instructed on how to
operate it safely.
l Never attempt to adjust, repair or service the snow
plow/dozer blade while the tractor engine is
running.
*Do not allow others near the snow/dozer blade
while it is being used.
*Use the snow plow/dozer blade only in daylight, or
good artificial light.
*Always lower the snow plow/dozer blade com-
pletely to the ground when leaving it unattended to
prevent it from being accidentally lowered and
causing injury. Make sure blade is locked in
“DOWN” position due to spring-assist.
*Always operate the tractor at reasonable speeds
to prevent the blade from catching an object and
stopping the tractor abruptly.

OPERATION AND NORMAL CARE
Transporting
For maximum ground clearance, transport the blade
to and from work areas fully raised and angled
straight ahead.
AWARNING
Be particularly careful and operate at low trac-
tor speeds in any area where the blade can
hook on solid objects. Such objects can
cause the tractor to be jarred or come to an
abrupt stop.
Operation On Slopes
Never operate on slopes greater than 30 percent
(16.7”) which is a rise of 3’ (91 cm) in lo’ (305 cm)
forward. Use two rear wheel weights (one per wheel)
when operating on slopes greater than 20 percent
(11.3”).
Always operate up and down the face of slopes, and
never across the face. Use a slow ground speed on
slopes.
Dozing and Snow Plowing
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 grade to your advantage. Plow downhill and
set the blade angle
so that plowed material (especial-
ly snow) is moving downhill as it leaves the blade. For
large
drifts of snow, bite off small amounts instead of
plowing a full blade width.
Always use full engine throttle and use the ground
speed control lever to control ground speed and
obtain the needed power to move the material.
Operate at a safe speed, depending on conditions, so
that you have complete control of the tractor. Rear
wheel weights and chains are recommended for slip-
pery surfaces.

42” Snow Plow/Dozer Blade
Normal Care
After dozing jobs, hose down the blade to remove
excess dirt. Coat bare metal surfaces to prevent rust-
ing. Lightly oil all pivot points.
If the wear plate (A, figure 9) on the bottom of the 42”
blade is worn excessively, replace it
wrth a new one
by removing the six carriage bolts (B), lo&washers
(C) and nuts (D).
ADJUSTMENTS
Lift Rod
For initial setting, place front set collar (A, figure 10)
1” from rod guide with blade fully lowered. Place rear
set collar (B) against spring (C). Tighten the
setscrews in the two set collars. To adjust, perform
the following:
1. Fully raise the blade by raising on the tractor lift
lever. Measure distance between scraper bar and
ground. If it measures approximately
6”, it is prop
erly adjusted. If not, proceed to step 2.
2. Lower the blade. Loosen the setscrew in the front
set collar. Move the set collar back to increase
clearance or forward to decrease clearance.
Tighten the setscrew. Recheck the measurement.
MOTE: D%rent ground contours may require differ-
ent adjustments. Lower the blade to adjust rear set
collar. Moving the rear set collar toward rear will allow
the blade to follow a rolling contour. The farther back
the rear set collar is positioned, the more the blade
will float. Moving the rear set collar toward the front
will increase blade down pressure.

42” Snow Plow/Dozer Blade
Skid Shoes
Alternate holes are provided to permit adjustment of
the shoe assemblies for raising and lowering the
blade to various working heights (see figure 11).
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 capscrews (A,
figure 11) and move the skid shoes (6) up or down to
desired height. Tighten the capscrews securely.
Blade Angle
To adjust the angle of the blade, proceed as follows:
1. Lift the blade off the ground using the tractor lift
lever.
2. Remove the pivot pin (H, figure 1 and E, figure i),
move the blade to desired angle and reinstall the
pivot pin in a diierent hole.
Spring Tension
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 in figure 12 rather
than cause damage. The blade will go back to original
position after object is cleared.
To adjust spring tension, hold rear nut (A, figure 12)
and loosen front nut (B). Tighten rear nut (B) to
increase spring tension or loosen nut to decrease
spring tension. Tighten front nut (8) so the two nuts
are drawn firmly together.
