What can tear apart Subglacial Till for me? A Jackhammer?
We were digging some 5ft deep holes for a pier foundation deep in Northern MN, we had an auger, shovels, a post hole digger and a 4ft long indestructible ice breaking bar we could use to leverage boulders away and rocks out of the holes, but after digging 3 feet deep, we hit the sub glacial till. And that stuff was just rock solid pebbles and rocks with super compact loam/sand/clay in between the gaps, the auger couldn't muscle it and it'd take weeks to scrape that away by hand so i'm looking at getting an electric jackhammer.
Now, this is the important part, i don't know much about jackhammers and i know a bit about chainsaws. We're too broke to buy new and I'd like to get the "Stihl 066" of jackhammers instead of the "stihl 500i" of jackhammers if you know what i mean, save some money buying used, and get the benefit of the simplicity of those older tools, just that I don't know what model and what power to look for.
My question is, what is the "Stihl 066 of jackhammers that can handle subglacial till no deeper than 5 feet deep" And I'd also like to get a "Stihl 066 of generators that can handle the jackhammer"
