Bernie, I would pull the fuse and look at the filament. It's easy to see if it is burned out. However, if you turn on the key and the PTO light does not illuminate on the dash, then the fuse is probably okay. The problem with reading a fuse in a circuit is that it is much more difficult to do. If you read voltage across a good fuse, you will get zero volts. If you measure one side of a blown fuse to ground, it will be 12 volts and the other side may be 12 volts also even if the fuse is blown because there may be just enough resistance in the supply path to raise the open side to 12 volts as long as there is no more load than a tester draws. The safest way to read a fuse is to remove it and read for zero resistance leg-to-leg.
