under the watchful eye of another
responsible adult.
2. Be alert and turn machine off if children
enter the work area.
3. Before and when backing up the machine,
look behind for small children.
4. Never allow children to play with the
machine or attachment even when they are
turned off.
5. Never allow children to operate the
machine even under adult supervision.
6. Use extra care when approaching blind
corners, shrubs, trees, or other obstructions
that might hide children from sight.

OPERATION
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 S tability
Use DR® Tire Chains for extra traction and
stability. Call 1(800)DR-OWNER(376-9637)
to order.
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
®
ALL-TERRAIN™ MOWER engine is
DR
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 spar k plug wire
NOTE: Run the DR® SNOW THROWER a
few minutes after blowing snow to prevent
freeze up of auger.
before unclogging.
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.

OPERATION
Snow Removal Methods
When removing snow, do not use the DR® SNOW THROWER as a dozer blade to push snow. Let the
DR® SNOW THROWER work its way through deep drifts. If the speed of your DR® ALL-TERRAIN™
MOWER is too fast, the DR® SNOW THROWER may become overloaded and clog. For best results,
raise the DR® SNOW THROWER and remove the top layers of snow, or take a half-width pass. A
second pass with the DR® SNOW THROWER will remove the remaining snow.
IMPORTANT: Use full RPM power when removing wet, sticky snow. Low RPM power will tend to
clog the chute.
NOTE: In heavy snow, engage and disengage the clutch lever to reduce the ground speed to a level
that will allow the engine to keep its full revolution.
!
WARNING! To avoid serious personal injury, do not use hands or feet to unclog chute.
Do not attempt to clear clogged chute of snow while DR
running. If the chute clogs, disengage the drive shaft, shut off the engine, remove the spark
plug wire and wait for all movement to stop, and then clear the snow from the chute.
A definite pattern of operation is required to thoroughly clean an area of snow. These patterns will
avoid throwing snow in unwanted places as well as eliminating a second removal of snow.
®
ALL-TERRAIN™ MOWER engine is
Where it is possible to throw the snow to the
left and right (above), as on a long driveway, it
is advantageous to start in the middle. Plow
from one end to the other, throwing snow to
both sides without changing the direction of the
discharge chute.
If the snow can only be thrown to one side of
the driveway or sidewalk (above), start on the
opposite side. At the end of the first pass,
rotate the discharge chute 180 degrees for the
return pass. At the end of each succeeding
pass, rotate the discharge guide 180 degrees to
maintain direction of throw in the same area.
