I know that 8ton excavators and above will move these easy but can anyone with practical experience moving these blocks with a tractor chime in? What size tractor have you used and were able to move these? and stack them at least 2 high. Ecology blocks are generally 2x2x6' and approx 3000-4000lbs depending who you ask and how they're built. I'm wondering if I can come close using an L47 either FEL or backhoe. Can get a trailer with a few close to the location that I would need them at.
