The shop owner could potentially have a truck/trailers setup with 3 Demo mowers, and a bunch of fert that he purchased at wholesale cost. Tell me he isnt going to hurt your business? Or...... 2 compaines buy mowers from him. The money he made selling them mowers he bought his own set at his dealer cost, and sends a crew out cutting in the same area as the other 2 companies. The other 2 companies just funded their own competition. Its just really shady and sly IMO.
