Is there a guideline for calculating the amount of force needed to push a digging implement into different types of soil?
That's true. If you try to push a grounding rod in by hand, you can't do it obviously. If you do the same thing and fill the hole with water while you wiggle it, you can drive a 6' grounding rod all the way into clay by hand. I've done it!
I'd look into using a small sprayer pump and reservoir with some perforated tubing wrapped around the tool to lubricate it.
