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.

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.

*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.

8. Assemble the chain (A, figure 4) to the tractor as
follows:
a. On left-hand side, remove the upper self-tapping
screw that holds bumper to frame. This is the hole
used for installing chain in the following steps,
using one 5/16-18x l-114 capscrew (B), two 5/16
washers (D), and one 5/16 locknut.
b. Place one 5/16 washer onto the screw. Then place
the chain on the capscrew, and then the other
5/16 washer.
c. Insert the capscrew (B, figure 4) as shown. From
inside frame, install
5/16 locknut onto capscrew.
Tighten snug only at this time. The spring (C) will
be installed in “Installation” section (step 6), and
hardware will be tightened.

5. Remove the bracket
(J, figure 5) from the tractor
hitch by removing four pins and safety clips.
6. Reinstall all pins (king pin, pivot pin, clevis pins)

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.
