Abstract: A lawnmower attachment comprises a bearing assembly pivotally mounted on a lawnmower housing, and having a shaft driven from a power take-off of the lawnmower. The shaft can have an edge-cutting blade attached thereto, or the edge-cutting blade can be removed and replaced by a grinding wheel, so that the attachment can be used to sharpen the lawnmower blades or other blades. Pivotal movement of the bearing assembly connects or disconnects the shaft with the power take-off, and such movement is controlled by a hand lever on the lawnmower handle. The hand lever has a latch for releasably retaining the attachment in inoperative position.
