Abstract

A rake, for handling crops such as hay lying on the ground has a framework for connecting to a tractor and with >=2 adjacent pronged wheel rakes, the prongs are set on the sides of the wheels which revolve about vertical axes in the opposite direction to that of movement; the prongs consist of rigid rods pointing outwards and downwards at an acute angle, they are freely hinged to swing upwards and backwards. The inner sleeves of the arms bearing the prongs are nylon coated at the pivot point. The design eliminates the occurrence of fatigue fracture of the rake prongs which arises when they are spring loaded.
