This is a beast for very little money. I am glad I got the 2 man configuration and my son helps me. It bent up a shear pin, it's that strong, but we didn't feel a lot of stress during that dig. In the future I'll try to clear it up out of the hole immediately when it starts to bind and see if that avoids bending the shear pin.I couldn't get the bent shear pin out by mechanical means, but I used an electric demo hammer (jackhammer) with the point bit and the shear pin popped out. I may try a weaker shear pin in the future, like the ones for my snowblower, so it will break rather than bending into a shape that is hard to remove. (Don't go stronger, but weaker should be fine.)Someone suggested a square shaft, and I think the high priced Little Beaver augers have that. But then you need a system to limit the stress back into the gearbox, since there's no effective shear pin. The high-priced Stihl 2 man auger BT360 uses a different bit attachment system.Let me reiterate, it's much easier with 2 users. Not only do you have twice the shoulders controlling the torque, but you're balanced in the direction between you so you can stand normally and the drill will be straight.

This was perfect for digging our holes in the rocky ground. I would recommend this product.

This is great worth the money

A very useful machine. I've owned this for a few years now and have drilled over 80 holes with it mostly 12" for concrete footers for my decks and posts for my farm. Agreed you need to be cautious of starting it with or using the throttle lock at all. Its easy enough to continuously engage the throttle while drilling. My fuel lines suffered some deterioration over time and were easily replaced. I'd buy again.

The only reason I gave it a 4 ⭐ is because it won't shut off at times. Otherwise, it's wonderful!!!!
