Far as I've been told and read, Fortune only works on blocks that drop an item; diamond ore, melon blocks, etc. There is an expensive donation feature that allows enchanted repairing.
They have fly and with fly they can set the fly speed to 4, which is really fast, and then they get and Eff 5 axe and just plow through rows which would take a normal person, for example, 30 seconds it would take them 10 seconds.
fortune does not work on any plants, except for the chance to get extra seeds when breaking grass and wheat. Fortune also increases the drop rate of flint from gravel, it gets up to 100%. Also, it also will work on coal, redstone, lapis, gold, iron, nether wart. It does not effect the drop rate of any other item in the game, only those stated above.
