Pin apparatuses and methods are disclosed having particular suitability for use with machine handles such as those associated with walk-behind machines such as lawnmowers. A pin apparatus can include a housing defining an opening for receiving at least a portion of a pin. A pin can be provided having an elongated pin body with a proximal end section and a distal end section. The pin body can be adapted for positioning at least partially through the opening of the housing where the pin is movable with respect to the housing according to a method disclosed herein from an extended position where at least a portion of the distal end section extends to a predetermined extent outside of the opening, and a retracted position where the distal end section is in a retracted position from the predetermined extent. A handle can be provided external from the housing for moving the pin whereby movement of the handle moves the pin between the extended position and the retracted position.

The pin apparatus of claim 20 wherein the cover portion also defines edges adapted for engaging the upper surface of the housing container when the pin is in the retracted position. 22. The pin apparatus of claim 18 wherein the housing container is positioned adjacent a positioning hole and wherein at least a portion of the distal end section of the pin body is adapted for extending into the positioning hole when the pin is in the extended position, and wherein the distal end section of the pin body is positioned out of the hole when the pin is in the retracted position. 23. A pin apparatus for a walk-behind machine, the pin apparatus comprising: (a) a housing comprising an elongated cylindrical body and defining a central opening there through for receiving a pin; (b) a pin having an elongated pin body, the pin body having a proximal end section and a distal end section of a greater diameter than a diameter of the proximal end section, the pin body being adapted for positioning at least partially through the central opening of the housing where the pin is movable with respect to the housing from an extended position where at least a portion of the distal end section extends to a predetermined extent outside of the central opening, and a retracted position where the distal end section is in a retracted position from the predetermined extent; and (c) a handle external from the housing and attached to the proximal end section of the pin, the handle being rotatable and having having a cover portion adapted for movement against a surface below the cover portion, the pin being movable between the extended position and the retracted position by rotation of the handle. 24. The pin apparatus of claim 23 further comprising a biasing member positioned within the housing and biasing the pin toward the extended position. 25. The pin apparatus of claim 24 wherein the biasing member is a spring and wherein the spring contacts the distal end section and extends toward the proximal end section. 26. The pin apparatus of claim 23 wherein the handle comprises a grip portion and a cover portion. 27. The pin apparatus of claim 26 further comprising a housing container, wherein the housing is positioned within the housing container and wherein the cover portion of the handle includes a lower surface adapted to engage a correspondingly shaped upper surface of the housing container when the pin is in the extended position. 28.
