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
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.

1. A variable speed control system for a walk-behind working machine, comprising: a control system base;a handle having a recess disposed in an edge of the handle;a control lever comprising a lever arm having a first end that is pivotably attached to the control system base and a second end substant
1. A variable speed control system for a walk-behind working machine, comprising: a control system base;a handle having a recess disposed in an edge of the handle;a control lever comprising a lever arm having a first end that is pivotably attached to the control system base and a second end substantially opposing the first end that comprises a grip portion, the control lever being 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 and a second angular position at which at least a portion of the grip portion is positioned within the recess of the handle; anda control connector in communication between the control lever and a machine component, wherein the control connector is configured to control the machine component to be in a first operating state when the control lever is in the first angular position, and wherein the control connector is configured to control the machine component to be in a second operating state when the control lever is in the second angular position. 2. The variable speed control system of claim 1, wherein the handle is attached to the control system base. 3. The variable speed control system of claim 1, wherein the control connector comprises a control cable connected between the control lever and a machine component. 4. The variable speed control system of claim 3, wherein at least a portion of the control cable is contained within the control system base. 5. The variable speed control system of claim 1, wherein the control lever is pivotable at least about 35 degrees between the first angular position and the second angular position. 6. The variable speed control system of claim 1, wherein the first operating state comprises a disengaged state of the machine component; and wherein the second operating state comprises an engaged state of the machine component. 7. The variable speed control system of claim 1, wherein the machine component comprises a variable transmission for a self-propel system of the working machine; and wherein the engaged state comprises operation of the self-propel system at a predetermined cruising speed. 8. The variable speed control system of claim 1, wherein an outer surface of the grip portion of the control lever is substantially flush with an outer surface of the handle when the control lever is in the second position. 9. The variable speed control system of claim 8, wherein the control lever is selectively pivotable to a third angular position at which the outer surface of the grip portion of the control lever is depressed into the recess of the handle, wherein the control connector is configured to control the machine component to be in a third operating state when the control lever is in the third angular position. 10. The variable speed control system of claim 9, wherein the third operating state comprises an over-stroke state of the machine component. 11. A variable speed control system for a walk-behind working machine comprising: a control system base;a handle having a recess formed in an edge of the handle;a control lever comprising a lever arm having a first end that is pivotably attached to the control system base and a second end substantially opposing the first end that comprises a grip portion, the control lever being selectively pivotable with respect to the control system base among a first angular position at which the grip portion of the control lever is spaced apart from the handle and a second angular position at which an outer surface of the grip portion of the control lever is substantially flush with an outer surface of the handle; anda control cable connected between the control lever and a machine component, wherein the control cable is configured to control the machine component to be in a relatively low-speed operating state when the control lever is in the first angular position, and wherein the control cable is configured to control the machine component to be in a relatively high-speed operating state when the control lever is in the second angular position. 12. The variable speed control system of claim 11, wherein the control lever is selectively pivotable to a third angular position at which the outer surface of the grip portion of the control lever is depressed into the recess of the handle, wherein the control cable is configured to control the machine component to be in an over-stroke operating state when the control lever is in the third angular position. 13. A method for varying a speed of a walk-behind working machine, the method comprising: pivoting a control lever with respect to a control system base to any of a variety of angular positions, including a first angular position at which a grip portion of the control lever is spaced apart from a handle, a second angular position at which at least a portion of the grip portion is positioned within a recess disposed in an edge of the handle, and a third angular position at which the outer surface of the grip portion of the control lever is depressed into the recess of the handle;wherein pivoting the control lever to the first angular position controls a machine component to be in a first operating state;wherein pivoting the control lever to the second angular position controls a machine component to be in a second operating state; andwherein pivoting the control lever to the third angular position controls a machine component to be in a third operating state. 14. The method of claim 13, wherein pivoting the control lever to control the machine component comprises actuating a control connector in communication between the control lever and a machine component. 15. The method of claim 13, wherein pivoting the control lever between the first angular position and the second angular position comprises pivoting the control lever at least about 35 degrees. 16. The method of claim 13, wherein the first operating state comprises a disengaged state of the machine component; and wherein the second operating state comprises an engaged state of the machine component. 17. The method of claim 16, wherein the machine component comprises a variable transmission for a self-propel system of the working machine; and wherein the engaged state comprises operation of the self-propel system at a predetermined cruising speed. 18. The method of claim 13, wherein pivoting the control lever to the second angular position comprises pivoting the control lever to a position at which an outer surface of the grip portion of the control lever is substantially flush with an outer surface of the handle when the control lever is in the second position. 19. The method of claim 13, wherein the third operating state comprises an over-stroke state of the machine component.
