Abstract
The forward and reverse directions of a motorized walk-behind vehicle are controlled by a walking operator through a control linkage which includes a lever pivoted on the control handle which the operator grips during operation of the vehicle. The control lever has two grip portions which are disposed in angular relation to one another and which move the control linkage for achieving forward and reverse directions of the vehicle when the grip portions are selectively pivoted toward the control handle. The control linkage is connected to a pivotable belt tightener supporting a pair of belt idlers which are selectively brought into tensioning engagement with forward and reverse belts upon pivoting the belt tightener in opposite directions. This forward-reverse control is particularly useful with a V-belt drive from an engine having two output shafts from the same side of the engine.
