Abstract: A height-adjusting assembly for wheels of an implement such as a tiller having an implement handle attached to a base and extending upwardly and rearwardly from the base, and having an adjustment bar for the wheels disposed adjacent the bracket. A locking mechanism selectively interconnects the adjustment bar and bracket, and includes a remote control wheel-adjusting handle movably mounted on the implement handle and having a manually-actuated portion remote from the connection of the bar and bracket for selectively fixing the wheels at a predetermined adjusted height. The locking mechanism includes a lock pin movably mounted on the bracket and selectively connected to the bar, and the wheel-adjusting handle includes an elongate rod having one end connected to the lock pin, the other rod end providing the remote manually-actuated portion.

Abstract: An adjustable handle bar assembly for a physically-guided implement such as a tiller having a handle bar rotatively mounted in a handle bar socket provided by a curvilinear panel web end and curvilinear margins of recesses formed in side flanges of a handle panel. An adjustable connection between the handle bar and the side flanges selectively adjusts the angular disposition of the handle bar in its socket. The rotative axis of the handle bar in the handle bar socket is defined by the curvilinear panel web end that embraces one side of the handle bar and the curvilinear margins of the recesses in the side flanges which embrace the other side of the handle bar. The adjustable connection includes laterally spaced arms secured to the handle bar, a bracket secured to each of the side flanges, and fasteners detachably connecting the spaced arms of the handle bar to the brackets.
