The one I borrowed from my neighbor has a massive cement counter weight on the rear. I noticed in moving dirt it can get tippy if there's too much in the bucket. This little workhorse can pull its own weight around the property. I moved a mountain of dirt in no time.
Everyone borrows this machine. They abuse it too. I replaced the left rear axle and axle bearing. And welded the front spindle when I was returned broken. The front spindles need gussets and probably the 1" spindles too.
