A universal stringer head assembly including a cylindrical housing with an interior diameter with the geometry of a cone or wedge with a plurality of orifices passing from the exterior surface to the interior surface. Each orifice is sized and shaped to receive a fastener therethrough. Ideally, at least three orifices are equally spaced about the external circumference of the housing, facilitating the rotatable attachment of at least three fasteners to the rotatable shaft of an associated piece of lawn equipment, for example an edge trimmer.

A multi-functional garden implement comprises an underframe connected with a supporting shaft. A pushing handle is fixedly connected to the underframe, and wheels are connected with the supporting shaft. The multi-functional garden implement further comprises a rotating bracket, which is connected to a power source. A working head is connected to the power source. The rotating bracket is rotatably connected to the underframe and capable of driving the working head to swing to both sides back and forth. Between the underframe and the rotating bracket, there is also a locating mechanism which can secure the rotating bracket onto the underframe. The present multi-functional garden implement is capable of adjusting the position of the working head, so as to meet various requirements for the working conditions of gardening work.

A multi-functional garden implement comprises an underframe, and a power motor is secured to the underframe. The multi-functional garden implement also comprises an adapting tube, inside which a transmitting shaft is rotatably connected. One end of the transmitting shaft connects to a working head. A locking sleeve is secured to the underframe, and the end of the adapting tube movably inserts into the locking sleeve. There is a locking piece designed on the locking sleeve, which allows the locking sleeve to clamp the adapting tube and secure the adapting tube onto the locking sleeve. The present multi-functional garden implement can replace the working head quickly, so that it has functions of cutting, micro tilling, etc.

A method of controlling a mower implement includes sensing a separation distance between the mower implement and an adjacent windrow with an outboard distance sensor. The sensed separation distance is then compared to a defined separation target. The computing device indicates that a course of the mower implement is on-target when the separation distance is approximately equal to the defined separation target. The computing device indicates that the course of the mower implement is drifting in a first direction when the separation distance is less than the defined separation target and greater than zero. An offset distance is sensed between the mower implement and a standing crop edge. The computing device indicates that the course of the mower implement is drifting in a second direction when both the separation distance and the offset distance are substantially equal to zero.
