I just bought two Toro 26 hp Kohler EFI 62 inch last Oct. I have been having problems getting the electrical sytem wet when I wash them. The manual clearly states not to get too much moisture in the area of the wiring harness of which I have been careful. One mower has been fine, the other runs terrible after washing. In fact, when I went to my dealer to pick them up after a 20 hr. checkup, he too washed them and the one would not start. I had to come back the next day and pick it up after it had time to dry out. Is anyone else having this problem? Any suggestions? I would like to keep my mower clean but if this happens everytime, I won't be able to!
