OPERATION   

STEP 5  
OPERATING INSTRUCTIONS:  

1.   Make sure the snowblower is clear of snow before engaging the snowblower.  

2.   Make sure that the auger and impeller operate freely.  

3.   Start the tractor engine.
  

IMPORTANT: USE FULL ENGINE R.P.M. WHEN REMOVING WET OR STICKY SNOW. 
LOW R.P.M.  WILL TEND TO PLUG THE CHUTE.  

4.   Engage P.T.O. slowly and maintain engine speed at 3/4 to full throttle.  

5.   Low range works best for most conditions. Adjust speeds to match snow conditions. The snowblower  

works best with plenty of snow being fed into the blades. In light snow (4’’ to 6’’ or 10 to 15 cm) increase  
travel speed.  

6.   Float position may be used, but carrying some of the weight with the power unit gives better traction. May  

require frequent lifting and lowering on 4-wheel drive units. If drive belts slips, adjust drive belt tension  
according to power unit manual. Never put down force on the snowblower.  

7.   Rotate chute using the auxiliary hydraulic control lever. Try to blow snow with the wind on windy days.  

8.   Set the angle of the deflector according to the distance the snow must be thrown and to prevent property  

damage.  To  change  the  deflector  angle,  loosen  the  two  deflector  knobs  &  adjust  the  deflector  to  

the  appropriate angle and retighten the two knobs securely. If equipped with an Electric Deflector Kit, use 

the  toggle switch for up or down deflector movement.  

9.   When removing snow, do not use the snowblower as a dozer blade to push snow. Allow snowblower 

to  ingest  snow  at  its  own  speed.  If  the  speed  of  your  tractor  is  too  fast,  the  snowblower  may  
become  overloaded and plug. For best results, raise the snowblower and remove a top layer of snow. A 
second  pass with the snowblower will remove the remaining snow.

   

CLEARING A CLOGGED DISCHARGE CHUTE:  

Hand  contact  with  the  rotating  impeller  inside  the  discharge  chute  is  the  most  common  cause  of  inju-
ry  associated with snowblowers. Never use your hand to clean out the discharge chute.  

To clear the chute:  

1.   Lower snowblower to the ground and set parking brake.
  
2.   SHUT THE ENGINE OFF & REMOVE KEY!  

3.   Wait 10 seconds to be sure that 

all moving parts 

such as the impeller blades have stopped moving.  

4.   Disconnect wire from the spark plug(s) and keep wire away to prevent accidental starting. Always use a 

clean-out tool (chute shovel) supplied with this snowblower.  NEVER USE YOUR HANDS! 

ASSURE CLEAR DISTANCE IN THE DIRECTION OF THROWING SNOW. OBJECTS 
CAN BE  PROPELLED FROM BLOWER CAUSING POSSIBLE DAMAGE TO PROPER-
TY OR INJURY TO  PERSON.

BE ALERT! WATCH FOR BURIED OBJECTS IN THE SNOW WHICH COULD BE 
THROWN OR CAUSE  DAMAGE TO MACHINE.   

NEVER TRAVEL AT SPEEDS THAT WOULD CAUSE DAMAGE TO THE MACHINE OR 
INJURY TO THE  OPERATOR IF THE MACHINE WERE TO BE STOPPED SUDDENLY BY 
AN IMMOVABLE OBJECT.   

READ THE TRACTOR OWNER’S MANUAL CAREFULLY. BE THOROUGHLY FAMILIAR 
WITH THE  CONTROLS & PROPER USE OF THE ATTACHMENT. KNOW HOW TO STOP 
THE ATTACHMENT &  DISENGAGE THE CONTROLS QUICKLY.
