Might be worth changing the fuse holder. Any corrosion in that area can cause problems. Or the wiring is shorting somewhere.
Good luck Phil :)

Make sure you have a good ground on pto clutch. You might also adjust the air gap on the clutch. I believe the proper adjustment is .012" according to posts here on this site. If the air gap is too wide or not properly grounded then the clutch will pull too many amps. But this is just my half-fast opinion......

Sounds like a clutch problem not a fuse problem.

you need to check your clutch resistance. hook a multi meter on ohms to the 2 wires coming out of the clutch. it should read 2.5-3.6 ohms. any lower than the 2.5 and you have a bad clutch that pulls to many amps/resistance and is causing your fuse/melting issues. replace the clutch.

I agree with Phil. This is a bad connection issue. There is excessive resistance in the fuse holder and clutch connector. It's either corrosion or just loose connectors. Try cleaning up the connectors and tightening them up a little. A light squeeze on the female spade usually does the trick. If the connectors are too far gone, replace them.
