It can work 2 ways, many years ago I had a Mcculloch chain saw and I took it to a shop to get it serviced and the only conversation from them was to "take it back to where I bought it". I went up the road to another shop and bought a new Farm Boss,from memory it was about $800 back in the early eighties. If they hadn't been so abrupt I would have bought a new one from them. Even with ride on mowers that are a bigger dollar value, most of the ones that end up on ebay are so clagged out that by the time you put a few parts into them the cost of the parts is greater than what people are prepared to pay. I repair a few of them but at the end of the day I get little for my labor and a lifetime of skills I have developed but it helps fill in the days and keeps me using the grey matter and hopefully will offset the onset of dimentia
