SAFETY PRECAUTIONS
Notice…
A safe operator is the best assurance against accidents. All operators, no matter how experienced they
may be, should read this operator's manual and all other related manuals before attempting to operate a
DR® SNOW THROWER. Please read the following section and pay particular attention to all safety
recommendations contained in this manual and those labeled on the DR® SNOW THROWER and on
the DR® ALL-TERRAIN™ MOWER.
Before Operating the DR® SNOW THROWER
1. Read and understand this operator's manual
and the DR® ALL-TERRAIN™ MOWER
operator's manual. Know how to operate all
controls and how to stop the unit and
disengage the controls quickly.
6. Never attempt to make any adjustments
while the engine is running. Read this
manual carefully to acquaint yourself with
the equipment as well as the DR® ALL-
TERRAIN™ MOWER Operator's Manual.
Working with unfamiliar equipment can lead
to accidents. Be thoroughly familiar with the
controls and proper use of the equipment.
2. Never wear loose, torn, or bulky clothing
around the DR® ALL-TERRAIN™ MOWER
and the DR® SNOW THROWER. It may
catch on moving parts or controls, leading to
the risk of accident.
7. Replace all missing, illegible, or damaged
safety and warning decals. See list of decals
in the Operator's Manual.
3. Before using the equipment, thoroughly
inspect the area where the equipment is to be
used and remove all objects that may
damage the equipment.
8. Do not modify or alter this equipment or any
of its components, or any equipment
function. Doing so will void your warranty.
4. Disengage the clutch and shift into neutral
before starting the engine.

SAFETY PRECAUTIONS
Operating the DR® SNOW
THROWER
Never operate the DR® SNOW THROWER
without good visibility and lighting.
9. Prolonged exposure to loud noise can cause
impairment or loss of hearing. Wear a
suitable hearing protection such as earmuffs
or earplugs to protect your valuable hearing.
1. Do not make mechanical adjustments while
the unit is in motion, the DR® SNOW
THROWER is raised, or the engine is
running.
10. Always wear eye protection during operation
(safety goggles, face shield, etc.).
11. Never allow anyone to operate the
equipment until they read the manual
completely and are thoroughly familiar with
basic DR® ALL-TERRAIN™ MOWER and
equipment operation.
2. Do not put hands or feet near rotating parts.
Keep clear of discharge opening at all times.
Do not use hands or feet to unclog spout.
3. Never allow anyone to sit or stand on the
equipment at any time.
12. Always make sure all equipment
components are properly installed and
securely fastened BEFORE operating.
4. Before leaving the DR® ALL-TERRAIN™
MOWER unattended, take all necessary
precautions. Park the DR® ALL-TERRAIN™
MOWER on level ground, place the
transmission in neutral, set the parking
brake, disengage the driving system, place
all levers including auxiliary control levers
in neutral, shut off the engine and remove
the ignition key.
13. Adjust collector-housing height to clear
gravel or crushed rock surface.
14. If the DR® SNOW THROWER starts to
vibrate abnormally, stop the engine
immediately, disconnect the spark plug wire
and check for cause. Excessive vibration is
generally a sign of trouble.
15. Never operate the DR® SNOW THROWER
without guards and other safety protective
devices in place.
5. Exercise extreme caution when operating on
or crossing gravel driveways, walks, or
roads. Stay alert for hidden hazards or
traffic.
16. Do not direct the discharge chute at
bystanders or animals. Ejected objects may
cause injury.
6. Do not run the engine indoors except when
starting engine and transporting attachment
in or out of building. Carbon monoxide gas
is colorless, odorless and deadly.
Read the separate DR® ALL-TERRAIN™
MOWER Operator's Manual carefully before
using the machine. Lack of operating
knowledge can lead to accidents.
7. Do not attempt to operate on steep slopes or
near embankments.
8. Use extra caution when backing up.

OPERATION
General Preparation
Snow Removal
1. Use a winter grade oil in your DR® ALL-
TERRAIN™ MOWER. See the engine
manufacturer's owner's manual.
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.
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.
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.
!
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.
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.
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.
!
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.
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.
NOTE: Run the DR® SNOW THROWER a
few minutes after blowing snow to prevent
freeze up of auger.
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® ALL-TERRAIN™ MOWER engine is
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.
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.
