초록 ▼

An improved riding lawn mower includes a vehicle frame having a front end, a rear end, and a rear motor deck that is secured to the rear end of the frame. A drive motor is mounted above the motor deck while a rear wheel assembly engaged with the motor, is connected to the bottom of the rear motor deck. The mower also includes a front wheel assembly connected to the front end of the vehicle frame. A vehicle body and driver\s seat are attached to vehicle frame. A steering column is cooperatively connected at its lower end to the front wheel assembly and includes at its upper end, a steering wheel positioned within reach of the operator seated on the mower. A steering mechanism is linked between the lower end of the steering column and the front wheel assembly. The steering mechanism is positioned above the front wheels of the mower and turns the front wheels asynchronously so that the lawn mower can be driven along an arc path having a radius approximately half the length of the vehicle frame.
