Hello everyone. I just recently finished off my great John Deere mower that I love and I would really like to fix it. My back yard is a bit of a war zone and I hit a stump really hard and now I need a new crankshaft and flywheel. I was wondering because I've seen the prices for these things new if I can buy one of the many mowers that are for sale cheap in my area that don't run and interchange the parts (if they are good of course). I have an '08 JS25 with the "mowmentum" self propel and a series 675 Briggs and Stratton engine. How can I find out if the crank and flywheel from other mowers will fit mine? I really want to save my mower....it's the best I've ever had and has taken a beating over the last six years. Thanks!
