Abstract
A control system can be used for a walk-behind self-propelled machine that includes a handle, a power source, a drive assembly, and an implement selectively driven by the power source. The control system can include a touch sensor located on the handle configured to transmit a contact signal indicative of an operator of the walk-behind self-propelled machine physically contacting the handle at a predetermined location. The system can further include a controller that is in electrical communication with the touch sensor and configured to enable the power source to drive the implement, such as a lawnmower blade, when the controller receives the contact signal.
