Angry Blowing fuse turning key

I have a LT1050 and while cutting(literally the last row) it died. I saw the fuse blew and every time I put a new one in, it blows as soon as I turn the key. I have checked all connectors visually and seem ok. I have checked the ground and looks to be ok. Any suggestions would be greatly appreciated! I’m not great with diagnosing shorts with meter. I Have taken the deck off unplugged the PTO, and any other plugs individually and it still blows instantly! New battery also.

Could be a short in the keyswitch or harness. Not knowing your particular tractor. Is the back of the keyswitch screws on wire connectors or a plug?

I'd look for rubbed wires. Solenoids and lights seldom blow fuses. It's rare.

You need to know what year tractor you have, then you can get a copy of the wiring diagram here:

I worked on 1 similar to yours and found a bad headlight bulb that the filament had blown and was touching the base of the bulb making a short and blowing the fuse

I've seen that before also, and is possible. But it doesn't happen often. Definitely something to check.

Look on the serial number tag. I doubt it's printed on it, but may be. The wiring diagrams have a harness number on them. Or at least the one I downloaded did. Maybe you can find the harness number on yours.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
