Foot operated control linkages overlie the conventional control lever operating system on a spin turn mower to operate the mower in either forward or reverse directions. Each control linkage uses a foot pedal to control the speed of the mower while the control levers remain operable, even while the mower is moving, to change the forward or reverse direction of travel of the mower. The forward control linkage includes a first set of springs that pull the control levers against a stop while a second control spring prevents the first springs from moving the mower until the foot pedal is depressed. Thus, when the foot pedal is allowed to return to a non-depressed position, the mower will revert to a neutral detent position in which the mower is not powered in any direction.
