That happens when the contacts become corroded. If there was one ohm of resistance between the fusebox contact and the fuse, at only 10 amps that would be a whopping 100 watts heating up the fuse.
Although you can measure the resistance across each fuse to see what the contact resistance is, it's tricky to measure low resistance with a typical multimeter. Alternatively, you can energize each circuit and see if you can measure any voltage drop across the fuse for that circuit; if you see even a tenth of a volt, that's enough to be concerned about.
I wouldn't bother with multimeter checks, though. Pull each fuse and inspect its contacts. If you see bright scratch marks like you see on the unburned contact in your photo, then it should be fine.

Today's Featured Article - Product Review: Lead Substitutes - by Mike Schordine. Lead was oriinally added to gasoline as an upper cylinder lubricant. It lubes the valves and seats. If you rebuild the motor, you could use hardened seats and valves, and unleaded fuel. But if your old tractor runs good, a simple lead substitute added to the gas is a perfectly reasonable solution. And, if you are like me, your tractor is under cover, but it sits outside. So with every temperature change, the humidity in the air collects in the fuel tank, in the form of water.
