Why does the fuse keep blowing in your cub cadet garden tractor?

There's a few reasons and some things you need to check. What electrical circuit is the fuse protecting to start with? Is there electrical wires coming to and from the fuse? If so, the most common problem is that a live wire has worn through it's insulation by rubbing against a peice of steel and causing a direct path to ground, a spark, which overloads the fuse and blows it. Also check to see if the fuse is the wrong amperage size for the circuit.
