This 2017 L3901 has me in such a bind! It started blowing fuses when I would move the forward /reverse peddle. I have gone over and inspected every safety switch, connector wire everything on the whole tractor and can find no visual sign of shorts ect. I replaced the safety switch on the peddle. $140.00 later but still nothing! I am obviously not doing something right and seriously need help as I rely on this tractor for my living!

To find a short disconnect the wiring in the middle of the circuit. If the fuse still blows the short is on the battery side. If not its on the ground side.

Once you know which side its on repeat that divide and test process on the shorted side. Keep doing that until you find the exact location of the short.

Have you looked for mice and or rats chewing the wiring up? Sometimes them little sumbeaches can play havoc on the wiring.
