Abstract
A preferred embodiment of a sulky includes a removable, adjustable foot platform, replaceable axles, and a hitch including stops that limit the extent of pitch, roll, and yaw motions between the sulky and the towing vehicle. The foot platform preferably projects downwardly from the frame on which the axles are mounted. The foot platform is mounted on a frame, and the frame preferably is structurally stronger than the foot platform.
Claims17
A sulky, comprising:
- a frame comprising at least one formed, structural member extending in a substantially horizontal direction at a first height;
- a foot platform removably mounted on said frame and projecting downwardly from said frame at least one inch;
- first and second horizontal axles mounted on and projecting from said frame at said first height;
- wheels mounted on said axles;
- and
- a hitch mounted to said frame for hitching said frame to a towing vehicle, said hitch including at least one left-to-right horizontal shaft to provide for pitch motion and at least one vertical shaft to provide for yaw motion between said sulky and the towing vehicle.

4 more elements
A sulky, comprising:
- a rigid, substantially U-shaped frame;
- a less rigid foot platform bolted onto and projecting downwardly from said frame;
- first and second axles bolted to said frame;
- first and second wheels mounted on said first and second axles, respectively;
- a hitch mounted on the front portion of said sulky, including three axes of rotation, a pitch axis, a roll axis, and a yaw axis;
- and
- stops which limit the amount of pitch, roll, and yaw of said hitch.
4 more elements
A sulky, comprising:
- a frame comprising at least one substantially horizontal U-shaped portion having left, right, and front sides;
- a foot platform removably secured to the frame, with the foot platform surrounded by said U-shaped frame portion and extending downwardly from said U-shaped frame portion;
- first and second axles mounted on said frame;
- and
- wheels mounted on said axles, wherein said foot platform extends downwardly below said axles;
- and
- a hitch projecting from the front side of said U-shaped frame member for hitching said sulky to a towing vehicle;
- wherein said hitch includes at least one left-to-right horizontal shaft to permit pitch motion and one vertical shaft to permit yaw motion between the sulky and the towing vehicle.
