I see this a lot, the dirt that gets sucked into the belts from fan draft eats at the pulley till it wears the "V" flat, then the belt is drawn down into the worn "V" and it flairs the outer edges like the one in the picture,,no one normally looks at the pulleys, but on larger tractors with bigger fans it becomes a real problem,, the belts will slip and squeal, so they get tightened up more, then the water pump bearing and the alternator suffer from the extra tension.
