Abstract
A riding lawn mower having zero turn capabilities has the engine mounted on the front of the frame. A drive system includes first and second hydrostatic transmissions for use in driving the back wheels. A grass bag may be mounted to the back portion of the frame and provides a counter balance to maximize the weight distribution. A discharge chute transfers cut vegetation from a mower deck to the grass bag and provides rear center discharge.
