BT 45 Earth Auger is rated 4.0 out of 5 by 11.
Rated 1 out of 5 by from Horrible Purchase I bought this auger roughly 4 months ago and it has spent more time at the repair shop vs actual field work. The clutch on this thing is garbage, total waste of money and am shocked Stihl would sell such a terrible product. We have a large fleet of a variety of Stihl products and love the brand but this has been a total disappointment. This BT 45 Auger we purchased was strictly used to plant 1 gallon plant material in freshly installed bioretention soil which is pretty much like fresh screened topsoil which this thing should absolutely handle but it cant. In the few months we have owned it we have returned it for clutch repair three times which is unacceptable when you pay this kind of money for a Stihl Product

Rated 5 out of 5 by from Expensive, but worth it if you have to plant a lot of stuff... I am a homeowner that prefers to buy professional tools for the jobs I have to do. We have a lake property that needed over 600 plants to be installed on what amounts to a cliff (we must have climbing gear on and be in a harness). I knew in order to get the job done quickly and correctly, this tool would be essential. This tool is unusual, so I had to call one of the bigger Stihl dealerships to get everything ordered correctly (most dealers I called have not even heard of this and they were incorrectly trying to order the wrong bits).In short, this tool was amazing for the job it is intended to do. With basically 3 men, we planted 600 plants in very challenging environment in 1 3/4 days. The landscaper said had we not had this tool, it would have taken 6 days, so it was money well spent.Starting: Initially, either through lack of experience or the breaking in period, the auger was a real bear to start. I followed the instructions, but it just wanted to flood. I ended up taking out the spark, and spraying in some WD40 in the chamber to get it to start for the first use. Afterwards, I follow these steps and it has worked every time... Press the prime button THREE TIMES. Put it in neutral. Put it on full choke. Lock the throttle. Pull the cord about 3 times. It will sorta fire. Advance it to non choke. Keep pulling until it starts (normally 4 or 5 times). Let it warm up before releasing the lock. If you pull much more than 3 times in choke, it will flood.Bit size: We used a 4 inch bit exclusively the entire weekend. The bits are not cheap (around $90). I would have loved to have a 3 inch and a 5 inch. They make both, despite saying it will only handle a 4 inch auger. As long as you aren't pushing it through super rooty soil, you can definitely make use of the 5 inch bit. To plant larger items, I would drill (4) 4 inch holes, and then pull the dirt out. A LOT EASIER than digging a big hole. If you want to plant a lot of tulip bulbs, then get the 3 inch.Depth of digging: Despite what the previous reviewer said, I was able to nearly sink the head of the unit. It will go deep if you clear out the hole periodically.Roots: Smaller roots this will chew through. However, the unit would definitely choke off if the root was bigger. I found that if I got to a large root, I would put the unit in reverse, and push into the root for a few rotations. That was normally enough to break the root and I could put the gear back in forward and proceed.Handle: I never had the handle come lose. Not with 600 holes and a good number of choke offs with larger roots. While the unit normally would choke off it it got bogged down, on about three occasions, it bit into what I was angering, and slung the unit around. The handle is about waist high. You figure out the rest... So be careful with the unit in soil that may give some kick back.Fatigue: I didn't have too much fatigue using this for long periods. For the most part, I worked the tool, not the other way around.Type of soil we worked in: Clay top for about 4 inches, then fine dirt with a healthy mix of small roots (ranging from 1/4" to 3/4")Gas efficiency: It doesn't hold much gas, but it seemed to operate a decent amount of time between fill ups.Gear system: This is my only real complaint. The gear system is very simple, and sometimes you have to rotate the bit a little, or spin up the unit, in order to transition from Neutral, to Forward, then to Reverse.Cost: This thing is pretty expensive for what it is, but there isn't much competition. I wish it was cheaper, but I buy Stihl for the quality and because this was made in the USA along with a great warranty.

Rated 1 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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

Rated 5 out of 5 by from 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 from 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.

Rated 4 out of 5 by from 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.
