AUGER SYSTEM
23
System Description
• The auger and impeller are driven by a belt from the engine crankshaft.
• An idler pulley is drawn against the belt when the control bale is engaged.
• The belt then drives a large pulley on the back of the impeller shaft.
• The impeller shaft enters the rear of the auger housing, driving the impeller through a roll pin.
• The impeller shaft continues forward to a “T” shaped worm-gear transmission.
The transmission drives the auger shaft.
• The auger system uses four individually stamped flights that draw the snow inward and into the impeller.
• The impeller then throws the snow out of the discharge chute with more force than augers alone could gener-
ate.
