Rated 1 out of 5 by Not a 'real' auger powerhead. Bought this as an auger powerhead, which is how they advertise it. In reality this is simply a gas powered drill and that is all. Sure, you can attach an auger bit to it and it will dig a hole, but not at all like an actual auger powerhead. Not to mention that the handle which came woth it will not stay where you set it. If the machine gets in a minor bind, and it will, the handle spins around, requiring you to stop, loosen handle, readjust handle and the tighten again. Drill and repeat!Our machine didn't make it but a few days before it had to have a new carburetor. It's very unreliable still, with tough starts and sometimes not starting. Power is just not there, not even for a 4" auger bit and 10" of depth. If you are digging soft top soil then it is perfect. Anything else and it will work you harder than you want to be worked, considering the tool was purchased to take the work out of the equation. We bought another brand auger powerhead and it would eat this one! October 18, 2016
Rated 5 out of 5 by Great auger! Honest Pest Solutions uses the BT 45 to install all of our termite baiting systems. It is a great auger for termite and pest control companies. Not heavy, uses different auger bits and sizes. It will pay for its self in no time at all. The good news if that is what you use it for, it is a cheaper option than the bigger augers. With a 3" drill head the BT 45 has no problem going 12"-18" deep. Even in the Georgia red clay. June 3, 2016
Rated 5 out of 5 by Grow trees to protect the world I am from Indonesia, where we need to encourage to plant more trees, as most of the forest has been illegally sawn off in the past,Indonesia having more than 17,000, island, needs many kind of technologies to improve the forest by planting more and more trees, with the young generation,I had identified the solution, is to use BT 45, which is convenient and WILL keep the younger generation from moving out to the modern cities.I had browsed the SITHL sites, and unable to get dealers nearby with the BT 45.Can I get help from STIHL USA, to get two units, with complete accessories for plants send by airfreight, so that I can display them during the Forestry meeting to be held in the province of Maluku Utara on 15th of Feb, I will give full details once I receive the response from STIHL.I will pay for the product.This is for the community, to understand there are products, which can be used efficiently for better future January 31, 2016
Rated 5 out of 5 by 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 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.

Rated 5 out of 5 by BT45 As a large landscape company we use this drill with 3" and 4" bits for planting in prepped beds. It does its job exactly as designed.The added/moveable handle is a great feature on this drill. October 30, 2013
Rated 4 out of 5 by multi use property owners must have tool. Used for fence post in some pretty tough, compacted, & a bit rocky dirt . The BT45 kicked butt! chewed through dirt well beyond its purposed intention. Also worked wonders repurposed as a soil mixer just add amendments and let the BT45 go to work. It mixes soil like a kitchen mixer. May 22, 2013
Rated 4 out of 5 by 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) 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. March 27, 2013
Rated 5 out of 5 by Works Great! Bought this to plant flowers, dig holes for landscaping, and for post holes. I have also used it to soften dirt for trenches. It chews through roots, clay, and weed mat without difficulty. An awesome little machine! March 24, 2013
