I think I need to change the fuses on my troy built mower/tractor. How do I check to see if they need to be changed? How do I change them? How do I know what fuses to buy?

It should have a regular car fuse... (usually blue) and when you look at it, if the loop isn't melted in two in the fuse, its OK. Usually they are around the solenoid or battery. Just match the one fuse that's bad with a new good one.
