ABSTRACT:
A powered spinning tiller with a box beam extending transversely of the direction of travel includes a plurality of spinners each consisting of a prong holder and a drive gear disposed rotatably on bearings side by side, adjacent prong holders being driven to rotate in opposite directions by the gear drive. In order to create an economical method of constructing a spinning tiller by the simplest means, provision is made for each spinner to be journaled on only one bearing and/or bearing ring which is situated in a single plane.
