A ganged mower frame of the type which is intended to be towed by a vehicle. The frame includes a center cross bar, a right hand cross bar and a left hand cross bar. The right and left hand cross bars are each pivotally connected to the opposite ends of the center cross bar for rotation about horizontal axes. A tow bar is provided having a pivotal connection at its forward end for attachment to a towing vehicle and an attachment at its rear for rigid connection to the center cross bar. A pair of forwardly extending mower support arms are provided with each support arm being pivotally mounted for rotation about a horizontal axis on the center cross bar near the ends thereof. A mower mounting bracket is attached to the forward end of each forwardly extending mower support arm with each bracket attached to its arm for rotation about the longitudinal axis of its arm. At least one rearwardly extending mower support arm is pivotally mounted for rotation about a horizontal axis on each of the center cross bar and right and left hand cross bars. A mower mounting bracket is attached to the rear end of each of the rearwardly extending mower support arms with each bracket mounted for rotation about the longitudinal axis of its mower support arm. Hydraulic pistons and cylinders are mounted on the center and right and left hand cross bars for lifting the mower mounting brackets relative to the cross bars for transportation when the unit is not mowing.
