Is this a new thing? I rented one from my local lumber yard - our tool rental place doesn't have one. I've been in a lot of rental shops over the years and this was the first one I've seen. Now I see HD rents them.
Anyway, this thing is the tits.
Last fall I put in a fence and rented two man earth auger to drill 24 8" x 24" holes. It took all day and nearly killed us. I rented this for about the same money and drilled 17 8" x 24" holes in less than an hour by myself. It even has its own built in trailer for transport. This has got to be the greatest invention since man started digging holes in dirt.
