Saxman,
I have had a woods loader and now on a different tractor a bush hog loader.
I can't say enough good about the loader, you won't be dissapointed in the specs. I am completely impressed with the mounting frame and I can lift the back end of my full size extended cab pickup clean off the ground with my bush hog on a thirty horse tractor. Cost was right in the neighborhood of any other aftermarket loader. Unfortunately I have no experience with Kubota loaders but I'd bet my paycheck bush hog would surpass their specs.
