ABSTRACT:
A device for displacing crop lying on the ground such as a side-delivery rake or tedder, has a frame supporting a row of ground-driven rake wheels each of which is movable up and down with respect to the frame. The device can be coupled to a tractor by a fastening structure that includes a frame portion passed through a central hole in one rake wheel. The frame portion connects the beam carrying the rake wheels, to a drawbar of the frame portion. By passing the frame portion through the rake wheel, the fastening structure can be of minimal dimensions reducing the damaging effect of forces applied to the fastening structure during use of the device. The rake wheels are similar to one another except the wheel with a central hole. The hole is surrounded by a circular hub rotatably mounted on fixed rollers on a structure connected to the frame. A supporting ground wheel for the frame is pivoted to a frame support and the pivot interconnected with the frame by a stabilizer that resists the extreme pivotal movements of the ground wheel.
