Prune Picker (Feb, 1950)
Powered by the operator’s feet, a new machine rolls along the ground to speed the harvesting of prunes and other ground crops. A platform supports the operator in a prone position above his work. He flips the prunes off the ground into a hopper. A conveyor then carries them to a receiving box. When he wants to move the machine, he shoves two pedals with his feet. The inventor estimates one picker on the machine can do the work of three to five using ordinary methods.
