My $400 auger rental taught me a lesson about rocky soil
I figured I'd save time on a 50-foot run of posts by renting a one-man auger instead of hand-digging (like I used to do back in the day). Got it from the equipment yard for a weekend, cost me about $400 with the deposit. First three holes went fine, then I hit a patch of what looked like old construction rubble mixed with ledge. That auger bound up so hard it nearly twisted my arm off before the shear pin gave out. Spent half the next day with a digging bar and a shovel anyway, plus had to pay for the damaged bit. Did I just get unlucky with the ground, or do you guys always scope the soil before renting power tools?
