Abstract
A blower for conveying material includes a housing and a spout. The housing has a front wall, a rear wall and an arcuate side wall extending between the front and rear walls. A plurality of arms with paddles mounted thereon are rotatable within the housing to discharge material through the spout. Springs are provided to urge a portion of the housing side wall into a normal position while permitting this side wall portion to be flexed outwardly if a foreign object such as a rock impacts against the inside of the housing side wall with enough force to overcome the springs. Permanent deformation to the housing is thus prevented by the springs.
