Operator Safety

This snowthrower is capable of amputating hands and feet and throwing objects. Failure to observe the following

safety instructions could result in serious injury. Read these safety rules, and the safety rules in your tractor

Operator’s Manual, and follow them closely. Failure to obey these rules could result in loss of control of vehicle,

severe personal injury to yourself, or damage to property or equipment. The triangle in the text signifies

important cautions or warnings which must be followed.

Preparation

• Never attempt to make any adjustments while engine is

running.

• Thoroughly inspect the area where the snowthrower is

to be operated and remove all foreign objects.

• Adjust the skid shoe height to clear gravel or crushed

stone surface. See the Maintenance and Adjustments

section for procedure.

• One wheel weight on each rear wheel or rear weights is

required.

Operation

• Exercise extreme caution when operating on, or

crossing gravel drives, walks or roads. Stay alert for

hidden hazards or traffic.

• Never allow anyone in front of the machine while it is

operating.

• After striking an object or if unit starts to vibrate

abnormally, stop the engine, disengage the PTO, and

remove the key. Check for the cause and any damage

before restarting. Before any inspection, make sure all

moving parts have stopped.

• Take all possible precautions before leaving operator’s

position. Disengage the PTO, lower the attachment, set

the parking brake, stop the engine and remove the key.

• Never operate the snowthrower near glass enclosures,

automobiles, window wells, drop-offs, etc., without

proper adjustment of discharge angle.

• Do not overload machine capacity by attempting to clear

snow at too fast a rate.

• Never operate unit at high transport speeds on slippery

surfaces. Use care when travelling in reverse.

• Disengage power to snowthrower when transporting or

not in use.

• Never operate the snowthrower without good visibility

or light. Always be sure your feet are properly placed on

the footrests and keep a firm hold on the steering wheel.

DANGER Amputation hazard. The discharge

chute contains a rotating

impeller to throw snow.

Fingers can quickly become

caught in the impeller. Never

clear or unclog the discharge

chute with your hands. Always

use a clean-out tool.

Failure to observe these safety instructions will result

in traumatic amputation or severe laceration.

Hand contact with the rotating impeller inside the

discharge chute is the most common cause of injury

associated with snowthrowers. Never use your hands to

clean out the discharge chute.

To safely clear a clogged discharge chute, follow

these instructions:

1. Shut OFF the engine.

2. Wait 10 seconds to be sure the impeller blades have

stopped rotating.

3. Always use a clean-out tool, not your hands.

General

• Read this manual and the tractor Operator’s Manual

carefully. Be thoroughly familiar with the controls and

the proper use of the equipment.

• If snowthrower is equipped with a spring-assist tension

lever, never pull the spring-assist tension lever back

unless snowthrower is in fully raised position. The

spring is under tension when snowthrower is in lowered

position.

• Never allow children to operate the machine. Do not

allow adults to operate it without proper instruction.

• Do not carry passengers.

• Keep the area of operation clear of all persons,

particularly small children, and pets.

• Never direct discharge chute towards bystanders.

• Make sure all hardware is secure and that snowthrower

is in good operating condition.

• Check to be sure all safety devices and shields are in

place.

• Check that all adjustments are correct before using this

unit.

• Tire chains and two rear wheel weights (or Quick Attach

Weights) must be installed when using this attachment.

• A Lift Lever Kit is required for some of the models

covered by this manual, and must be installed as part

of hitch installation.

• Never operate on slopes greater than 17.6% (10°).

Recommended Accessories

A rear-mounted weight box can also be added for

additional traction. The maximum weight added to the

tractor should not exceed 35 lbs. per wheel, plus 100

additional pounds in the rear weight box.

For operation on slopes greater than 15% (8.5°), Quick
