Rated 4 out of 5 by It's a powerful little auger. I give it four stars because of the power of it. Unlike some other commenters, I find the unit to be lightweight.I have to take a star off because my auger is hard to restart. I broke the unit in very carefully. The first time I ran it I let it run at idle on top of a bucket for a full tank.I thought the hard to restart issue was peculiar to my particular auger. However, I found another person [that I've known for years] that has the same problem. October 7, 2015

Rated 4 out of 5 by Easily beats the competition We've tried four different makes of augers for restoration projects. We needed tools that could run all day, every day without problems or issues for several large restoration projects. We were planting several hundred thousand plants, and needed good tools. After being continually frustrated with other brands (including several highly recommended by our local tool dealer), we bit the bullet and paid extra for the stihl one person auger. We have not been disappointed. We've worn out a half dozen bits (6" & 4"), but the auger just keeps running. Well worth the money. July 21, 2013
Rated 4 out of 5 by A great tool, but the description should read "2 normal humans, or a circus elephant!" I have owned a Stihl Earth-Agar for ~ 5 years and I love it. We have used it to drill 4-foot postholes in rocky ground. Even with the 18" extension we buried the auger for each hole. Because of the rocks we would often drill 2 or 3 holes before we could get one deep enough. In one corner we made so many holes it looked like a prairie dog colony! The auger did a great job on this backbreaking task.We have also used it to dig a couple thousand planting holes (4" auger x 6" deep). It does this very well too.My only complaint is that calling calling this beast a "Lightweight, one-man auger," is misleading. I hire a crew of healthy, rugged Forestry majors every summer, and it requires s two to operate the thing for any length of time. One person can use it for maybe an hour, in soft soil, but I think it is actually dangerous to do it alone in rocky soil. Hit a rock and the auger STOPS, dead. All that torque has to go somewhere, so the handles jerk around. If you loose your grip, the power unit will whip around with tremendous force and could break your arm, or bust ribsEven if you don't have a problem with rocks, a second person comes in very handy when you are trying to pull the thing out of the hole it just made.If I ever have to put in another fence, I going to price renting that elephant, I mentioned in the summary.Never-the-less, I highly recommend this tool, and if anybody ever manages to break it, I will be at there local STIHL dealer by noon!
