3 medium potatoes
I have been looking at this question long enough. It depends on the size of the potato you have, you can leave the skin on, and you will still have 1lb. when you are done shredding, if the potato started out at 1lb.
If you take the peel off, then you should calculate 1/8th of a pound off, so when you peel have that whole potato in your hand, it should weigh 1&1/8th pound before you peel it.

If the potato you are shredding weighs 1 pound then I guess 1 pound.
