ABSTRACT:
The present invention is directed to a lawn mower wherein a lawn mower body frame includes a motor and an operatively connected transmission. The lawn mower motor body frame is supported by front and rear wheels. At least the rear wheels are independently supported on separate shafts which are rotatably disposed with respect to the lawn mower body frame. Pulleys are positioned concentrically on each of the separate shafts in opposing, spaced apart relationship to define a gap therebetween. A belt is disposed in said gap and operatively connected to the motor through the transmission to impart rotation to the rear wheels. The pulleys, the separate shafts, and the rear wheels are positioned relative to each other to permit slippage therebetween to facilitate a change in the direction of the lawn mower.
