A self propelled, steerable, vertically adjustable, hydraulicly driven, ganged mowing machine for trimming nursery products. The machine generally includes a horizontal platform that supports a staggered array of mower decks. Each mower deck is driven by a hydraulic motor operatively connected to a mower blade for trimming the nursery products. The platform is slideably connected to right and left vertically stationary frames such that the platform is vertically adjustable with respect to the ground, via a hydraulic cylinder interconnecting the platform and each frame. Each vertical frame includes an independently controllable hydraulically driven traction drive motor operably connected to a drive wheel for propelling the machine. The mowing machine also includes a prime mover. The prime mover drives a number of hydraulic pumps. At least one of the hydraulic pumps drives the hydraulic motors which drive the mower blades. At least one pump drives the traction motors mounted on the vertical frames, and at least one pump drives the hydraulic cylinders for vertically adjusting the platform. The mowing machine also includes a seat for a driver, and controls for operating the gas engine, traction motors, and for engaging the mowers. The mowing machine is self-braking.
