Abstract
Abstract A trimmer supported on a dolly, each of which has a handle. The operator holds the dolly handle in one hand and the trimmer handle in the other hand. The trimmer is pivotally connected to the dolly whereby movement of the handle of the trimmer relative to the dolly handle changes the approach angle of the trimmer relative to the movement of the dolly. The pivotal connection is forward of the dolly wheels whereby raising and lowering the dolly handle effects lowering and raising of the trimmer and the corresponding depth of cut. The connection includes adjustment means to adjust the positions of the trimmer relative to the dolly.
