Patent

CA 2638272

A self-propelled concrete finishing trowel has a steering system that counteracts a portion of the load associated with operator manipulation of a steering handle. A steering linkage connects the steering handle to a rotor assembly. A steering assist mechanism, preferably including a torsion bar or a spring, imposes a preload on the steering linkage to reduce handle actuation forces. The steering assist mechanism reduces handle retention forces, required to maintain the handle in a particular position after moving the handle to that position, to less than about 20 lbs throughout the stroke of the operating handle.
