An improved riding lawn mower comprises a frame having steerable front wheels and rear traction wheels. Each rear wheel is independently driven by a separate transmission. A steering wheel is used to turn the front wheels to control the direction of movement of the rider. Linkage assemblies connected to the steering assembly declutch the rear wheel on the inside of a sharp turn to give the mower near ZTR turning ability. However, the declutched rear wheel freewheels to avoid tearing the turf and the mower does not speed up during the turn.
