I recently started building a deck in my house that required a total of 12 holes 36" deep. That mud blade worked great, the Eskimo power head was strong enough and luckily the gearbox worked well. I went into the project dreading day one as I started the holes. It was still a lot of work and I had to use an excavator to dig through the large rocks I encountered, but the mud drill saved me a lot of time and labor. My only advice is if you need to go deeper than 25 or 30 inches, get an extension. Also keep in mind that I fully expected to mess up my Eskimo power head because I recently bought one that attaches to my drill bit, but it has held up well.
