Operating Instructions

When operating on a slope, reduce speed and use caution to start, stop, and maneuver. Avoid sharp turns or sudden changes in direction.

When blowing through deep snow drifts, let the snowblower work its way through the drifts. For best results, raise the snowblower and remove a top lay- er of snow, then pass through the area a second time to remove the remaining snow.

When snowblowing, operate the engine at or near full throttle for the best snowblowing action. The engine is designed to be operated at full speed.

Use optional tire chains or optional all-terrain tires to improve traction.

Disengage the PTO clutch to stop the snowblow- er when driving the machine but not blowing snow.

Avoid damage to property and extra snowblowing work by carefully choosing the direction to move the snow. Orient the blower away from people and property due to the possibility of thrown objects.

To momentarily increase traction in case the drive wheels are slipping, use the lift switch to raise the snowblower slightly and transfer extra weight on the drive wheels.

Removing Snow

DANGER

DO NOT blow snow with bystanders in the area (especially children or pets).

A definite operating pattern is required to thoroughly clean snow from an area. Each pattern described below clears all the snow in one pass (of the pattern) and prevents throwing snow in unwanted places.

IMPORTANT: DO NOT use the snowblower as a dozer blade to push snow. Let the snowblower work its way through deep snow. If the tractor is driven forward into snow too fast, the snowblower may become overloaded and clog.

Use the following pattern where snow can be thrown only to one side. Start on the side farthest from where the snow will be thrown. At the end of the first pass, rotate the blower spout 180 degrees for the return pass. At the end of each following pass, rotate the spout 180 degrees to keep throwing snow in the same direction.

Throw Snow to One Side

Use the following pattern where snow can be thrown to both sides. Start in the middle with the blower spout directed to either the right or left. Drive from one end to the other in an outward spiral, without changing the position of the blower spout to throw snow to both sides.

Throw Snow to Both Sides

Clogging Checklist

In case of clogging, the snow throwing action will de- crease and finally stop. When this occurs, disen- gage the PTO clutch, stop the engine, disconnect the fuel solenoid wire [diesel engines] or spark plug wire(s) [gasoline engines], and remove the ignition key. Make sure all movement has stopped be- fore attempting to unclog.
