A sulky for transportation of an operator, attachable to a self-propelled vehicle, defines pivot axes, one of which is selectively lockable in order to preclude yaw motion. The sulky also includes caster wheels which are selectively lockable to permit or preclude free castering of said wheels. It also provides stops at the pivot axes for limiting the amount of pivot.

[ What is claimed is:] [1.] A sulky for use behind a self-propelled vehicle, comprising:a mounting bracket;a connecting arm mounted to the mounting bracket so as to permit the connecting arm to pivot about a first pivot axis relative to the mounting bracket;a coupler pivotably mounted to the connecting arm for pivoting about a second pivot axis;a platform pivotably mounted to the coupler so as to pivot about a third pivot axis; wherein said three pivot axes provide for pitch, roll, and yaw motion; andaligned locking holes at one of the foregoing mounts and a locking pin receivable in said aligned locking holes to prevent pivoting at that mount, whereby the user may remove the pin in order to provide for pivoting about three axes and may insert the pin to restrict pivoting to two axes.
