Abstract
An agricultural rake especially designed for gathering wide swaths of agricultural field crops into windrows prior to baling is provided. The rake includes a primary frame, a pair of secondary rake frames pivotally and shiftably mounted to the primary frame, and a plurality or bank of radially-tined wheel rakes supported by the secondary frames. Both the angle of deployment of the secondary frames as well as the distance between the frames is adjustable to accommodate different swath widths and windrow sizes. A unique rake suspension assembly provides for the easy shifting of the rake bases between the raking and transport positions while providing for desired damping of the rakes during raking operations.
