Yes, my wife watches the auger as it goes down and motions me to move the tractor forward as it goes deeper. One trick to minimize how much dirt you have to dig out with the manual post hole digger: Turn your auger off before you lift the auger out. Much of the dirt will stay on the auger blade.
I assume you are putting in wooden posts. I pre-mark the ground level required on the posts before hand with a felt pen so I can get the hole to the right depth easy. I also over drill the auger holes and keep sand in the tractor bucket to fill the hole back to the right depth. I also make a tripod out of 2 x 2 sticks (attached to the pole with construction screws) to hold the pole straight and level while backfilling.
Backfilling is the hardest and most time consuming part of putting a post in. I went from a 9 inch to 13 inch diameter auger to allow for more error in hole location and straightness, and to allow more room for a tamping stick. Contrary to one's intuition, it is actually quicker and easier to backfill and tamp an oversized hole.
