Abstract
A sulky includes a frame and a first and second wheel supports. The first wheel support extends along a first axis and is rotatably coupled to the frame about the first axis. The second wheel support extends along a second axis and is rotatably coupled to the frame about the second axis. First and second pedals are operatively coupled to the frame and to the first and second wheel supports, respectively. The first and second pedals are moveable relative to the frame for rotating the first wheel support about the first axis and for rotating the second wheel support about the second axis. A linkage operatively couples the first and second wheel supports for transferring movement of one of the first and second pedals to both of the first and second wheel supports to rotate the first and second wheel supports in unison respectively about the first and second axes.
