Abstract

A mower including a frame having a front portion, a rear portion, and at least one central longitudinal beam. The at least one beam is parallel with a longitudinal axis passing from the front portion to the rear portion of the frame. First and second wheels are positioned on opposite sides of the front portion of the frame and are spaced to define a track width of the mower, with the track width being a distance between a center portion of each of the first and second wheels. The first and second wheels pivot about a first longitudinal pivot axis and a second longitudinal pivot axis, respectively. The first and second longitudinal pivot axes are laterally spaced from the longitudinal axis between about 0% and about 20% of the track width.
