    Wish I had bought one of these years ago
    I purchased the BT45 last fall with the intention of planting spring flowering bulbs, spring annuals, small perennials and ground covers with the auger as a time and back saver. The auger has a 2 speed gear box which came in handy with denser clay soils in low gear, high gear is used for most soils though. Low vibration, good on fuel, starts up well, power is perfect for the augers intended use. This auger is not for installing big fence posts or very rocky, super dense soils. We installed ... read more 24 flats of pansies yesterday with the auger, amazing how much quicker, neater, loosens the soil well, can not imagine going back to digging with a trowel for smaller plants installs.

    Nice little tool up to Stihl standards.
    It's a great little tool for drilling planting holes in the ground. I have the 3" auger and it works great. Reversing feature is good for when the auger gets stuck...engineers thought this through. Use low gear all teh time, not sure what high gear is for...maybe the much smaller diameter wood boring bits.

    Beyond the suggested use...
    I bought and used two of these to plant a wetland mitigation site. I had to fabricate a piece to allow me to run a larger bit-- the 4" ones designed for planting one gallon plants. The ground we were working in is soft floodplain loam, but I was able to plant between 10-15k plants before the units broke down significantly, both in the gear box. Well worth the $$ invested vs a shovel / laborers. Ended up buying a 121 to finish the job of the one gallon plants, and used the 45's (after repairs) ... read more to finish planting an additional 120k small grasses. (Used the small bits designed for the machine) The only major issues other than the gearbox was the throttle cables. They got sticky fast and were difficult to actuate. The spark arrestors clogged within the first week, rendering the machine inoperable, but they are easy to remove.

    Couldnt ask for More
    I'm a 60 year old female who decided to install the earth anchors for my new shed myself. I've always been one to do anything I can myself. Well turned out that the shed required ten 30" anchors. I tried twisting one all the way down but couldn't get in down further than about 24 inches. I rented this auger and, wow, am so glad I did. It is extremely easy to use, very light, and started up after 2nd pull each time. I had all of the holes done in no time. Worked like a charm. If I had the need to ... read more buy one, this Stihl BT131 would be it. You wont be disappointed.

    Worth every penny, LOVE this machine!
    I am a fence contractor in Austin, TX, so I use this machine on a daily basis. I own a larger, more powerful one-man auger that you frequently see at rental facilities, but loading and unloading this other machine at 175 lbs by myself got to be a problem on jobs where I wasn't pulling a trailer with a low deck height. I have used at least 5 or 6 other brands through rentals or purchase, so I have a pretty good cross section of products with which to compare the BT131. After several weeks of ... read more web research, I decided to go ahead and pull the trigger on this machine due to its light weight and compact design (it fits easily on the passenger side floorboard of my truck). I was slightly anxious and skeptical that it would have the grunt to dig in the conditions that are common here in Austin; heavy hard pan clay and caliche on the east side and limestone on the west side. Now nothing short of a skid steer with a few hundred pounds of downforce will dig solid limestone, but for all other conditions this machine has far exceeded my expectations! I actually thought the little clutch bar that hits your leg to disengage the engine when you hit an underground obstruction was a little goofy and gimmecky. Wrong about that too! Anyone who has used other one-man augers before has experienced the beating that you receive despite the various claims of different anti-shock and clutch mechanisms. This thing actually works flawlessly and I wish I had discovered this auger years ago. So other pros...super light, easy to tote around a job site. Its great because you can lay it down on the side of its roll cage if you need to switch over to a root bar or your hand diggers to clear out a large root or loose soil and it stays running smoothly at idle till you pick it back up again. Power-wise, I've actually never been able to bog it down. It maintains steady power, or in the event of hitting something particularly hard it will just pop the clutch bar. So even as small and light as this powerhead is, with its gearing it has plenty of oomph to dig in just about any condition you can throw at it. Make sure you don't make the initial mistake that I did, which was trying to use off-brand auger bits from other machines that I already owned. The Stihl bits are perfectly matched for this machine and are deceptively efficient and sturdy despite how they look on the shelf. The thought and engineering that is evident in each Stihl tool that I have purchased is unmatched by any other brand that I know of. If Stihl makes a tool that fits your application, you just can't go wrong.

    Works great around the farm and my grave digging business
    I dig graves, and this machine really does a great job for digging for cremation urns, vaults etc...definitely easier than a shovel, and cheaper than hauling a mini excavator for this size job...ls very useful around the farm for putting in temporary corner posts for electric fences and other multiple uses...plan to put in some permanent fencing, using this to dig holes for concrete encased oilfield pipe posts...
