tool for working crop lying on the ground staff according to the direction of motion 1.

摘要

A hay machine for working crop lying on the ground, such as a side-delivery rake, a tedder or a combined hay-making machine has a tined carrier for redepositing worked crop on the ground and comprises rows of tines which, in operation, are rotated in a forward direction while being turned oppositely over at least part of their path near the ground. The tines, which are located near the ground, extend horizontally and in a forward direction with respect to the direction of machine movement. The carrier preferably mounts three rows of elongated tines that are each shaped as a lazy S and pointed at each end. A sun wheel and planet gear system drives the carrier as a whole while turning the tines to pick up crop, raise and deposit same to the rear of the carrier. The orientation of the tines can be adjusted by displacing the sun wheel relative to the frame and fixing same in position. A crop crusher is mounted adjacent the paths of the tines and spring means urges the crusher to adjusted positions in which crop is intersepted and worked further.
