A sulky includes a frame having a cross-member and a pair of shafts spaced from each other and extending from the cross-member forwardly along an axis. A first wheel support and a second wheel support each rotatably extend downwardly from the frame and each engage wheels, respectively. Each of the first and second wheel supports includes an adjustment feature defining a plurality of adjustment positions. The wheels are engaged with the first and second wheel supports, respectively, and are independently adjustable relative to the first and second wheel supports, respectively, to any of the adjustment positions. The plurality of adjustment positions of the first and second wheel supports are located along lines generally extending rearwardly along the axis and upwardly relative to the axis.
