I am getting parts together for this coming mowing season and I need some suggestions on what to try to find. I'm getting ready to go on Christmas Break from school next week and I'm gonna be out for a month, so I'm trying to get things together for the spring and summer as far as mower parts are concerned. I need some suggestions as to what kinds of machines to look for that are common for things to go bad on. I am going to hit the backlots of all the dealers around here, because they usually just abandon the dead machines back there. I know of where a diesel F-725 JD is that caught on fire that I could get cheap if not free. They say its been picked over, but I think I could rebuild the engine on it and use it in something else if its not too far gone. I also patrol the local dumps for such machines. I am stocking up on starters, pulleys, carburetors and other common items from what I know right now. But anyway, what brands of machines do I need to look for and what parts off those machines should I pull and clean up for sale? Thanks for any help. This is the first year I will be getting into commercial machines. I still will have residential machines as well too.
