ABSTRACT:
A control device which is fixed to the control arm of a concrete pwer trowel or concrete finishing machine approximately midway between the trowel and the trowel handle. The attachment, which is adjustable in length, relieves the operator from the necessity of controlling the power trowel by means of its handle and allows the operator to control the power trowel from various distances outside the perimeter of the poured concrete.
