A slow in turn system for a vehicle comprises an accelerator linkage that is linked to the input lever of a variable speed transmission. The accelerator linkage includes first and second link arms that couple a foot pedal to a rotatable cam plate. The link arm that connects to the cam plate is coupled thereto by a slider so that the connection point of that link arm may be moved towards and away from the pivot axis of the cam plate. The slider is moved away from the pivot axis of the cam plate during turns of the vehicle to reversely rotate the cam plate, and hence retard the input lever of the speed changing system, to thereby automatically slow the vehicle. This movement of the slider is accomplished by a connecting linkage extending to the steering system of the vehicle. In addition, the vehicle includes a cruise control system that can be set to obtain a particular forward speed but which allows the operator to temporarily speed up without subsequently having to reset the cruise control system. The slow in turn system works without affecting the position of the accelerator foot pedal and without requiring the cruise control system to be disengaged.

[ We claim:] [1.] A vehicle, comprising:(a) a movable frame on which an operator may be carried, the frame having a plurality of ground engaging wheels comprising a pair of drive wheels and at least one steerable wheel;(b) a steering system coupled to the at least one steerable wheel for changing the direction of movement of the frame to thereby turn the frame;(c) a speed changing system for changing the speed of movement of the frame, wherein the speed changing system comprises a single variable speed transmission coupled to the drive wheels;(d) an accelerator operatively linked to the transmission which accelerator can be engaged and moved by the operator to set a desired speed of movement of the frame; and(e) a slow in turn linkage extending between the steering system and the transmission for automatically slowing the frame during at least some turns of the frame without affecting the position of the accelerator.
