I have an exmark, zero turn that is approx. 15 years old and have just encountered my first problem. I suspect that I have some sort of an electrical short. I had problems starting the mower this spring and deduced that two fuses, (located under the seat) has shorted out. I replaced the fuses and used the mower for two cuttings until one of the fuses blew out. I've tried replacing the fuse again, but I blows when I try to start the mower. Any ideas how a novice mechanic should proceed ??????
