 SNOW THROWER Safety, Operation & Maintenance Instructions 

General Preparation 

1.  Use a winter grade oil in your DR

®

 

ALL-

TERRAIN

 MOWER.  See the engine 

manufacturer's owner's manual. 

2.  Make sure that the auger operates freely. 

3.  Adjust the skid shoes so that the DR

®

 

SNOW THROWER runs level. 

4.  Make sure that the DR

®

 SNOW 

THROWER is clear of snow before 
engaging the drive belt. 

!

 

WARNING:

 

1.  Read this Operator's Manual carefully.  Be 

thoroughly familiar with the controls and 
proper use of the equipment.  Know how to 
stop the unit and disengage the controls 
quickly. 

2.  Never allow children to operate equipment.  

Never allow adults to operate equipment 
without proper instruction. 

3.  Keep the area of operation clear of people, 

animals and debris. 

4.  Clothing worn by the operator should be 

fairly tight and belted.  Loose clothing 
should not be permitted because of the 
danger of getting into moving parts. 

Increasing Traction and Stability 

Use DR

®

 Tire Chains for extra traction and 

stability.  Call 1(800)DR-OWNER(376-9637) 
to order. 

Engine Speed 

!

 

CAUTION: 

Use only moderate engine 

speed when engaging the drive belt.  
Engaging the belt at high speed will shorten 
the clutch life. 

 

For maximum power, operate the engine at, or 
near, full throttle. 

Snow Removal 

Never use the DR

®

 SNOW THROWER as a 

snowplow.  Do not push the snow, let the 
SNOW THROWER work its way through deep 
drifts.  For best results, raise the SNOW 
THROWER and remove a top layer of snow.  
A second pass will remove the remaining 
snow. 
 
If ground speed is too fast, the DR

®

 SNOW 

THROWER may become overloaded and may 
clog.  Maintain a ground speed suited for the 
job to be done. 
 
In heavy snow, take on only enough snow to 
work easily.  Engage and disengage the clutch 
lever to reduce the ground speed to a level that 
will allow the engine to keep its full revolution. 
 

NOTE:

  Use full RPM power when removing 

wet, sticky snow.  Low RPM power will tend to 
clog the chute. 

 

!

 

WARNING:  Do not use your hands to 

unclog the chute.

  Use a short stick or board.  

Never attempt to clear clogged chute while the 
DR

®

 

ALL-TERRAIN

 MOWER engine is 

running.  If the chute clogs, disengage the 
drive belt, wait for all movement to stop, apply 
the parking brake, shut off the engine and 
remove the spark plug wire before unclogging. 

 

NOTE:

  Run the DR

®

 SNOW THROWER a 

few minutes after blowing snow to prevent 
freeze up of auger.
