clearing is one thing....
hmm... how DEEP must you dig !!! Around me 3 1/2 feet is 'frost', which of course varies nbased on where you live.
Doesn't make any sense to buy a 3' digger when you have to go 4' down.
Don't think my BX23S will lift a 4' unit.
other options, instead of buying is to
rent a proper machine or hire it out.
either way when you plan the job ahead, be prepared, it'll go faster, smoother, might save money too.
I've past up PHDs in the past, cheaper to hire it out. NO stones so guys can drill fast.
