Speaking as a biped it saves my back for strain.
A bipod will also save your back. It doesn't need to be anything fancier than a couple of scaff poles and a swivel clamp. A trailer winch can be fitted directly to one leg which makes life easier and safer than hauling on a rope. Push down on the tether to lift the kibble away from the hole with a 2:1 mechanical advantage. Just set up a slack back rope so that it doesn't all land on you head
I've even used this setup with one arm in a cast.
