ABSTRACT:
A belt drive arrangement is provided which employs a variator to interconnect a powered drive belt and a belt driven to operate either a transaxle or a transmission of a ground-engaging vehicle. The variator is secured to a pivotally mounted support member. The support member is joined to a speed control shaft which is rotatable in response to the actuation of either a foot pedal or a handle. Rotation of the speed control shaft repositions the variator with respect to idler pulleys associated with the driven belt so as to alter the vehicle's speed. Means are provided to rotate the speed control shaft by actuation of the pedal independently of the position of said handle.
