What causes fuse to blow when you engage pto on gravely zero turn mower?

A blown fuse when engaging the PTO (Power Take-Off) on a Gravely zero-turn mower typically indicates an electrical overload or short circuit. This can be caused by a faulty PTO switch, damaged wiring, or a malfunctioning mower deck motor. Additionally, if the blades are jammed or there is excessive resistance, it can also lead to increased current draw, causing the fuse to blow. Regular maintenance and inspection of electrical components can help prevent such issues.
