Yes Mike I heard that and expostulated loudly - a pitch fork is for pitching hay - as a farmer's daughter and ex smallholder I've done a great deal of that in my time - the ones I knew always had two slightly curved prongs. Originally you pitched sheaves of hay or corn with it - Pa could pitch a bale of straw with one.
A fork with four similar prongs was a muck fork for mucking out with. I've also done lots of that - horses, pigs, cows, goats, you name them, I've mucked them out - with a muck fork.
You dig with a garden or digging fork http://en.wikipedia.org/wiki/Garden_fork .
If you tried to dig properly with a pitch fork the tines would snap.
