Hi, new guy here! I have a model 425 that will not start at all. Story goes this spring I couldn't get the mower to engage, even replaced the PTO switch. My old farmer neighbor came up to go over it, he couldn't figure out what was wrong either. So he takes to a reputable dealer to get repaired. After 2 weeks he comes back with it, now the mower runs. I noticed right away there was a problem getting it started, a problem that I didn't have before going to the shop. I finally got it started, it ran for afew minutes and stopped; haven't been able to get it started since. I see the shop replaced the circuit board and almost all the wiring and new plugs. I can't even get it to puff using starter fluid, so I'm thinking something electrical has gone wrong. This really gets me mad considering the $347.00 repair bill! If I had a trailer I'd take it right back to them and complain. The neighbor doesn't seem to want to help again as I've asked him numerous times? Anyway, any body here know what I can try to get it going again? I appreciate any help. Thanks guys!
