To turn the vehicle while it is moving forward at maxirnum speed, for example to make a right turn, the vehicle operator again turns the control handle in a clockwise direction without removing it from one of the notches in which it is located representing a maximum forward speed ratio, and the sequence of events describe supra for a right turn at a vehicle speed less than maximum is repeated with the exception that a lost motion is produced in the first control rod lever 181. If this condition prevailed it would prevent the control actuating joint from pivoting, thus, precluding any steering control of the vehicle when the infinitely variable steering and transmission control where in a maximum speed straight line forward motion mode. 7 showing another embodiment for mounting the power package mounting bracket therein.
