Abstract
Variable speed control systems and methods for walk-behind working machines, such as lawnmowers and similar powered machines, can include a control system base, a handle having a recess formed in an edge thereof, a control lever including a lever arm that is pivotably attached to the control system base and includes a grip portion, and a control connector connected between the control lever and a machine component. The control lever can be selectively pivotable with respect to the control system base between a first angular position at which the grip portion of the control lever is spaced apart from the handle to control the machine component to be in a first operating state and a second angular position at which at least a portion of the grip portion is positioned within the recess of the handle to control the machine component to be in a second operating state.
