Abstract: A hydraulically operated gang mower trailer which is connectable to a tractor having a source of pressurized hydraulic fluid for actuating cylinders to raise and lower the mowers. The trailer has a tow bar assembly which permits connection to tractors at varying vertical heights. The trailer has a frame and reel mounting which minimizes the weight carried by the tractor. A stacked set of lever operated hydraulic spool valves which control the flow of pressurized hydraulic fluid to the hydraulic cylinders for lifting and lowering the mowers can be easily moved from tractor to the trailer by disconnecting a minimum number of hydraulic hoses.

Abstract: 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.
