SECTION 5:  CONTROLS

Engaging the Augers and Impeller

Power to the snow thrower attachment is activated by 
lowering the tractor’s lift lever and placing it into the 
lowest notch possible.

Move the tractor’s throttle lever into the FAST 
(rabbit) position and allow it to remain there for the 
most efficient use of the snow thrower attachment.

Move the tractor’s lift lever to the right before 
lowering it and placing it in any of the notches on 
the index bracket. This will engage the augers and 
impeller.

NOTE: The tractor’s lift lever cannot be in the engaged
(lowered) position when the tractor is driving in the
reverse direction. The tractor’s lift lever must be in the
disengaged (BLADES STOP) position when the shift
lever is placed in REVERSE or the tractor’s engine will
automatically shut off.

Refer to your tractor’s Operator’s Manual for more 
information regarding your tractor’s safety interlock 
system.

Lift Handle

The lift handle is located on the right side of the tractor 
and is used to raise and lower the snow thrower 
attachment.

To raise the snow thrower attachment off of the 
ground, pull rearward and down on the lift handle 
until you feel the lift latch on the right side of the 
snow thrower engage, locking the snow thrower in 
a raised position.

To lower the snow thrower, push downward on the 
lift handle until there is enough slack in the lift cable 
so that you may squeeze the trigger control. With 
the trigger control squeezed, gently allow the snow 
thrower to lower until it reaches the ground.

Chute Directional Control

The chute directional control assembly is found on the 
left side of the tractor and includes both the chute tilt 
lever as well as the chute crank. Both affect the 
direction that the discharged snow is thrown.

To pivot the upper section of discharge chute, 
affecting the distance and angle which the snow is 
thrown, move the chute tilt lever forward or 
rearward into a desired position.

The direction which snow is thrown can be changed 
by rotating the discharge chute with the chute 
crank. Turn the chute crank clockwise to rotate the 
chute and discharge snow to the left. Crank it 
counterclockwise to rotate the chute and discharge 
snow to the right.

SECTION 6:  OPERATION

This snow thrower attachment is capable of displacing snow and clearing a path a width of 42 inches.
Observe the following operating instructions for both effective and efficient snow removal.

Become familiar with and comfortable using all of 
your tractor’s controls as instructed in your tractor’s 
Operator’s Manual before operating it with the snow 
thrower attachment.

Make certain the correct weight and volume of 
motor oil in is your tractor’s engine as instructed in 
the engine Owner’s Guide packed with the tractor’s 
Operator’s Manual.

Always operate the snow thrower with the tractor’s 
engine at maximum RPM (full throttle).

NEVER override any safety features on either your 
tractor or the snow thrower attachment.

Make certain that all nuts, bolts, and hardware are 
fastened securely and tight on both the tractor and 
the snow thrower attachment prior to use.

Make certain the snow thrower is assembled 
properly and mounted to the tractor as instructed 
earlier in this manual.

Test all the controls (tractor lift lever, snow thrower 
lift handle, chute tilt lever & chute crank) for smooth 
operation prior to operating the snow thrower in the 
snow.

Make all adjustments (i.e. skid shoes, lift latch) 
before operating your snow thrower attachment. 
Follow instructions in 

SECTION 7: ADJUSTMENTS

 when 

doing so. 

Engage power to the augers and impeller BEFORE 
driving the tractor forward and into the snow.

Keep your tractor’s ground speed slow. The slower 
your tractor is traveling, the more effectively the 
snow thrower attachment can displace snow.

Adjust ground speed for snow conditions and 
become familiar with different snow applications. 
Your snow thrower attachment will operate 
differently in wet heavy snow than it will it light, fluffy 
snow.
