Claim:
1. An automatic turn-sensing ground speed reduction system for a walk-behind, self-propelled machine having a main operative assembly and a handle that extends behind the main operative assembly, the system comprising: an actuation mechanism disposed at a distal end portion of the handle and located at a rear of the walk-behind, self-propelled machine, the actuation mechanism being configured for use by an operator to assign a ground speed of the walk-behind, self-propelled machine; a control unit; and a sensor configured to transmit a signal to the control unit, wherein the signal corresponds to an angular velocity of the walk-behind, self-propelled machine measured about a vertical axis perpendicular to a ground surface on which the walk-behind, self-propelled machine can be self-propelled; wherein the actuation mechanism is configured to allow one handed control of the walk-behind, self-propelled machine by the operator, and wherein the control unit is configured to automatically adjust the ground speed of the walk-behind, self-propelled machine during turning movement of the walk-behind, self-propelled machine based upon whether the signal exceeds a predetermined threshold value of one or more of velocity, angular velocity, acceleration, angular acceleration, orientation, and/or gravitational forces experienced by the walk-behind, self-propelled machine.
