It's 1. or 2.


2. is easy enough to recheck. undo what you did and make sure something isn't touching somewhere it shouldn't be. Starter relay itself needs to be looked at.

1. needs to be gone through to see why the safety has shorted. Once you figure it out, deactivate the reverse cutoff on your own terms. That feature is a pia.

google- 2007 Cub Cadet LT1050 disable reverse cut off

Whichever of these two issues occurred closer to when the fuse started blowing is where I would look first.

edit- that switch also looks like a piece of junk. I would look at that too if 1 and 2 dont check out.
