发明名称 V-rake with windrow width adjustment
摘要 A V-rake includes a drawbar assembly adapted for connection to a tow vehicle, in combination with a transverse cross-member connected to the drawbar assembly. Wheels are mounted to the cross-member, to form a trolley for conveying the V-rake. A rake arm is mounted to each end of the cross-member, and includes a series of rake wheels. The rake arms are moveable relative to the cross-member between an open, operative position and a closed, transport position, and the rake wheels are moveable relative to the rake arms between a raised, inoperative position and a lowered, operative position. The transverse cross-member is a rigid, fixed-length member to increase the structural rigidity of the trolley. A windrow width adjusting arrangement is interconnected with the rake assembly, and includes a windrow forming rake assembly mounted to the transverse cross-member adjacent each end thereof. Each windrow forming rake assembly includes a rake wheel mounted to an outer arm, which in turn is mounted to an inner arm pivotably mounted to the transverse cross-member for movement about a vertical pivot axis. In this manner, the windrow forming rake wheels can be moved together and apart to adjust the width of windrow formed between the windrow forming rake wheels. An adjustable length member, such as a turnbuckle or hydraulic cylinder assembly, is interposed between the transverse cross-member and each inner arm, for controlling the position of the windrow forming rake wheel. The outer arm is preferably mounted for pivoting movement to the inner arm about a substantially horizontal pivot axis, to enable the windrow forming rake wheels to be moved between a raised, inoperative position and a lowered, operative position in response to operation of an actuator associated with the rake for moving the rake wheels between the raised, inoperative position and the lowered, operative position.
