Abstract: 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.

Abstract: A mounting arrangement for mounting a backpack device on a trailer includes a beam with lateral projections and hooks on the ends of the projections to receive the frame of a backpack device. Preferably, there is at least one strap for securing the device in a vertical position on the mounting arrangement. To mount the device on the mounting arrangement, it is pivoted downwardly, to hook the device frame over the hooks, and is then pivoted upwardly, into a vertical position, and is secured in the vertical position so that it cannot pivot back down to come loose.
