Abstract

A transportable trailing wide-swath wheel-supported implement such as a rock windrower is conveniently able to convert from wide-swath working mode to a transversely narrower folded mode for convenient transport of the implement. The folding elements are a drawbar and the wheel legs, each of these being pivotally attached to the implement frame about a substantially vertical pivotal axis. In working mode, the wheel legs and drawbar are extended at a relatively large acute angle or right angle to the frame whereas in transport mode they pivotally retract to assume relatively small acute angles to the frame. The wheel legs may be locked in either extended or retracted position. Between the drawbar and the frame is preferably pivotally connected a hydraulic piston-cylinder arrangement, permitting the angle of the drawbar to the frame to be adjusted and controlled. If the implement is of the type having a working element in ground engaging contact, means such as an additional hydraulic piston-cylinder arrangement are preferably provided to enable the working implement to be pressed against the ground and to remove the weight from the implement-supporting wheels, the wheel legs rising above the ground permitting the wheels to clear the ground thereby facilitating their repositioning about the pivotal axis of connection to the frame.
