Abstract
An expeller for discharging manure from the tank of a manure spreader avoids severe deformation when contacting rocks in the manure by having paddles fastened with shear bolts which are designed to fail whenever a predetermined load is exerted on the outer ends of the paddles. If the shear bolts fastening any one of the paddles should fail while the expeller is operating to discharge manure from the tank of a manure spreader, that paddle will be moved to a retracted position and will be held there until new shear bolts can be installed.
