摘要： A neutral lock mechanism for a direction and speed control pedal. Forward or down-toe motion on the pedal produces forward movement of a vehicle and rear, or down-heel, motion produces rear movement, while increased displacement of the pedal in either direction will produce an increase in speed. The neutral lock mechanism includes a latch pivotally connected to the pedal and spring loaded to a latching position in which the latch will engage the floor plate of the vehicle and prevent pivotal movement of the pedal. A lever is connected to the latch and projects upwardly through an opening in the pedal. The operator's foot, when in a normal operating position, will depress the lever and release the latch while mere accidental engagement of the operator's foot with the pedal will not release the latch and will retain the pedal in the neutral lock position.
