I have a deal with the tip shop to put aside anything with a motor for me. I can generally fill my trailer with mowers and trimmers for $20 or less. Even if I cannot get a particular machine going again for minimal outlay it will probably come in handy for bits. My yard is a sea of Rover chassis at the moment. I have two good runners heading of to a local auction next week that cost me around $10 each to get going well so hopefully someone falls in love with them and puts some cash in my pocket.
