Abstract
The propeller is for an agricultural sprayer, having a hub at the end of the driving shaft, and in which blades turn about their lengthwise axes. Protrusions extend at right angles to the blade stems, and are a clearance fit in holes in the hub. They are turned by a plate turning on the hub so as to vary the pitch of all the blades simultaneously. There can be a centrifugal clutch between driving shaft and hub, and the plate and hub can be spring-loaded together, generating friction so s to oppose relative rotation between them.
