ABSTRACT:
A self-propelled, walk-behind traction vehicle includes a power source, a pair of drive wheels and an improved operator-manipulated drive control mechanism for selectively coupling the drive wheels to the power source in a manner that allows the operator to control propulsion and steering of the vehicles. The drive control mechanism includes a friction drive unit having a pair of reversible, variable speed transmissions associated with respective ones of the drive wheels for selectively coupling the drive wheels to the power source. The control mechanism further includes a pair of independently swingable control handles configured to be gripped by the operator and operably coupled to respective ones of the transmissions so that the speed and direction of rotation of each of the drive wheels is controlled by swinging a respective one of the handles.
