A walk behind power equipment device, the walk behind power equipment device comprising a frame; an engine supported at least in part by the frame; a mobility assembly operably coupled to the frame and to the engine to provide mobility of the walk behind power equipment device responsive to operation of the engine; a working assembly operably coupled to the frame and to the engine to provide performance of a working function of the walk behind power equipment device responsive to operation of the engine; and an adjustable handle assembly operably coupled to the frame to provide steering inputs responsive to which the mobility assembly moves the walk behind power equipment device, the handle assembly comprising: a handle apparatus; at least one extension portion (182, 180); and a handle height adjuster, wherein the at least one extension portion (182, 180) extends between the handle apparatus used to steer the walk behind power equipment device and the frame of the walk behind power equipment device, wherein the at least one extension portion (182, 180) is operably coupled to the handle height adjuster, characterized in that the handle height adjuster is remotely adjustable to fix the at least one extension portion (182, 180) at a selected one of plurality of non-discrete positions relative to the frame over an entirety of a range of motion of the at least one extension portion (182, 180), the handle height adjuster comprising a released state activated remotely to enable movement of the at least one extension portion (182, 180) relative to the frame to any desirable point along the entirety of the range of motion of the at least one extension portion (182, 180) and a fixed state in which the handle height adjuster is not activated and the at least one extension portion (182, 180) is held fixed relative to the frame at a corresponding point along the range of motion of the at least one extension portion (182, 180), wherein the handle height adjuster comprises an air cylinder, wherein the at least one extension portion (182, 180) is split into two linearly extending rigid component portions, by means of a fixed extension portion and a movable extension portion, wherein a flexible joint is provided between the two component portions of the at least one extension portion, so that the at least one extension portion includes two linearly extending rigid portions that are connected to each other via the flexible joint as articulated joint, wherein the handle height adjuster extends between the component portions of the at least one extension portion, wherein the fixed extension portion is fixed to the frame and the movable extension portion is fixed to the handle apparatus such that lengthening or shortening of the handle height adjuster changes the angle between the two component parts and thereby changes the elevation or height of the handle apparatus. a handle apparatus; at least one extension portion (182, 180); and a handle height adjuster, wherein the at least one extension portion (182, 180) extends between the handle apparatus used to steer the walk behind power equipment device and the frame of the walk behind power equipment device, wherein the at least one extension portion (182, 180) is operably coupled to the handle height adjuster, characterized in that the handle height adjuster is remotely adjustable to fix the at least one extension portion (182, 180) at a selected one of plurality of non-discrete positions relative to the frame over an entirety of a range of motion of the at least one extension portion (182, 180), the handle height adjuster comprising a released state activated remotely to enable movement of the at least one extension portion (182, 180) relative to the frame to any desirable point along the entirety of the range of motion of the at least one extension portion (182, 180) and a fixed state in which the handle height adjuster is not activated and the at least one extension portion (182, 180) is held fixed relative to the frame at a corresponding point along the range of motion of the at least one extension portion (182, 180), wherein the handle height adjuster comprises an air cylinder, wherein the at least one extension portion (182, 180) is split into two linearly extending rigid component portions, by means of a fixed extension portion and a movable extension portion, wherein a flexible joint is provided between the two component portions of the at least one extension portion, so that the at least one extension portion includes two linearly extending rigid portions that are connected to each other via the flexible joint as articulated joint, wherein the handle height adjuster extends between the component portions of the at least one extension portion, wherein the fixed extension portion is fixed to the frame and the movable extension portion is fixed to the handle apparatus such that lengthening or shortening of the handle height adjuster changes the angle between the two component parts and thereby changes the elevation or height of the handle apparatus.
