摘要： A forage harvester is provided with a rotatable cutterhead (9), a solid cylindrical grinding stone (15), a motor (33) for moving the stone (15) along a path adjacent the cutterhead (9) and an adjustment mechanism for moving the stone (15) towards the cutterhead (9). During the final stage of the sharpening cycle the stone (15) is automatically moved along the path at a substantially lower speed in order to improve the finishing of the cutterhead (9), such that the shearbar (11) can be adjusted closer to the rotating cutterhead (9).

摘要： A multiple frame wheel attachment connectable to a handheld device, such as a gasoline powered weed trimmer. The wheel attachment has a pair of wheels attached to the ends of an axle and a pair of frame assemblies connecting the axle and wheels to the lawn trimmer. Both of the frame assemblies are mounted to the axle and to the shaft of the device. One of the frame assemblies is attached to the shaft near the operating unit of the device and the other frame assembly is attached to the shaft above the point where the first frame assembly is attached. The first and second frame assemblies support the shaft at two locations. The wheel attachment not only provides support during operation of the handheld device, but also functions as a stand so that when the device is not in use, it will remain in an upright position for storage, refueling service, and maintenance. The wheel attachment allows easy mobility of the operating unit over the work area. It may be used with a variety of handheld devices including lawn trimmers, lawn edgers, and metal detectors.

摘要： An adjustable mowing and trimming apparatus is presented which employs a unique wheel adjust mechanism and trimming assembly. The apparatus includes a frame to which at least two wheels are rotatably mounted at opposite sides of an adjustable linkage which is loosely coupled to the frame through a moveable pivot assembly. A mechanism is provided for manually adjusting the moveable pivot assembly to actuate the adjustable linkage and thereby reorient the wheels on either side of the frame. The trimming assembly is mounted at a front portion of the frame and includes a spindle head fixedly mounted to a spindle depending from the frame so as to rotate with the spindle. The spindle head substantially covers the spindle and is sized such that a distal end thereof rests proximate to ground when the trimming apparatus is operational. A trimmer head is adjustably clamped about the spindle head so as to rotate therewith. The trimmer head has a plane of cutting substantially perpendicular to the axis of rotation of the spindle and the cutting plane is infinitely adjustable within a range defined by a length of the spindle head.
