Abstract
A zero turning radius vehicle is disclosed having a power transmission operatively and independently engaged to each one of at least two driven wheels, and including at least one caster, supporting a portion of said vehicle weight, rotatably connected to the vehicle whereby the caster is operatively biased while the vehicle is operating at a side angle such that the caster neutralizes the gravitational force that would tend to drive the vehicle downward when traversing a slope.
