By the time you get to turning the compost at the bottom you'll be looking forward to your fume blanc and not caring if you got the last inch transferred. It's back breaking work. The first few forkfuls go fast but then each forkful gets heavier and heavier. Nearer the bottom, where it's damp, moving it with a soup spoon would be less strain on your body!
When you do get to the bottom use a barrel, fill the barrel* (not too full - test the weight) and then dump it in the next pile.
*using any type of shovel, spade, trowel
