I didn't die (obviously...). I didn't take a trip to the ER. I didn't even get seriously hurt... but damn that thing is dangerous.
My wife and I were installing two carports in our rocky New England property. You seriously can't dig more than a six inches without hitting multiple bowling ball-sized rocks on this property, and while the labor involved isn't an issue, the amount of time is. Considering that the anchors for the carports were about 2 and 1/2 feet long, and there were six of them per carport, and I didn't have access to a backhoe or any other power digging tools, I knew this part of the project was going to be a test of patience. After digging holes for three of the anchors and creating a new pile of stones in the yard, I figured there had to be a better way. So, a quick trip to Harbor Freight for a relatively cheap power tool sounded like a good idea. I figured I could use the auger to quickly drill holes in the area where the anchors would go, and widen the holes as needed to remove rocks. Win/win, right?

First, the thing requires 80-90w gear oil. It would have been nice if it said that somewhere on the box in case I needed to buy some before I got home, but luckily I just happened to have a bottle. Setup was really easy, but I quickly found out that the machine is very awkwardly balanced and not easy to control. It's all fine and dandy while you're drilling into soft or at least consistent dirt, but God forbid you hit a rock or a root. The first time I did, it nearly snapped my left wrist. I learned very quickly after that to stick with 1/2 throttle, and as soon as the auger starts to vibrate, be ready for it to spin in your arms. I also found that bracing it with my left thigh rather than my left wrist would give me enough time to let go of the throttle before damage was done. Some kind of clutch or even shear pins would be nice - I'd take replacing 20 shear pins in one day over snapping my wrist.
All in all, it worked out ok. Not great, but better than digging in this horrendous New England rocky soil by hand. Next time I'll just borrow a backhoe, but I can see this thing being handy for a few odd projects here and there.
In before girly man / real men dig holes by hand. I have too many hobbies to have time for that crap these days.
