I just got a brand new Exmark 52" 23hp Kohler. Well, I took it out to test it on my yard this weekend. I was cutting the grass (barely taking anything off the grass) when the mower suddenly died. So, I checked under the seat and saw 2 fuses there. One was blown. Replaced it, started mower, pulled PTO and then after a minute, the fuse blew and mower died. Replaced, started mower, pulled PTO and immediately died. Then, battery went dead and hard to charge. This is a brand new 2003 unit. Anyone have any ideas? As soon as the PTO is pulled, the mower dies and fuse is blown.
