Abstract
An agricultural implement for raking or spreading crop lying on the field, for example, mown grass, comprising at least one carrier rotatably driven around an upright axis and having upright shaft pins arranged in a circle, on each of which is journalled in a freely pivotable manner a crop-engaging, tine-shaped element of non-circular cross section, wherein a flexible member independently of each element is arranged so that the tine-shaped element is held in an outwardly directed position with respect to the upright axis, said tine-shaped elements preferably consisting of two or more tines in overlying position the bending resistance in the vertical plane of the superjacent tines differs from that of the lower-tine.
Claims14
An agricultural implement for raking a crop such as hay, comprising the combination of:
- a frame, a carrier rotatably mounted on said frame about a generally upright axis and means for rotatably driving said carrier about said axis;
- a plurality of tine assemblies mounted on said carrier in a circular pattern concentric with said axis whereby each tine assembly is subjected to centrifugal force as the carrier is rotated, each tine assembly including at least one tine element and pivot means freely pivoting such tine element about an upright axis to swing outwardly of the carrier to operative position in response to said centrifugal force, and spring means separate from each tine but engaging same to oppose inward deflection of such tine.
