Ok here is the sad story, lent my 643 bobcat to a friend. When i dropped it off i told him it needed gas. About an hour later i get a call from him that there was an explosion behind the seat and the machine was burning, fire department on its way,,,,, My question is this, IF SOMEONE ACCIDENTLY PUT GASOLINE INTO THE HYDROLIC FLUID WOULD/COULD THIS CAUSE IT TO EXPLODE????????????????
