All of a sudden the lawnmower gave a loud screech and eventually began to give off a rubber smell. It would cost about $60 for a repair guy to tell me what it would cost to fix. Does anyone know how expensive such a repair is likely to be (I would have a pro do it). Around here, an annual tune up costs $100. If a couple of hundred dollars, I would probably just buy a new one (thinking of the Honda HRN216VKA). My yard has some hills. With the Lawnboy, I never tried to pull the mower backwards, would just pick up the back end a bit to move it around. Any thoughts? Thanks.
