Diggerland is amazing, we took our kids to the one near (in?) Leeds (NW England, UK), for my son's third birthday, he was able (allowed) to operate all but the largest which I would estimate is somewhere in the 7.5T range. The diggers don't move, they're fixed in position, and don't rotate, but otherwise you have full control of the arm using the normal stick-type controls. My 4yo daughter picked it up far quicker than myself despite me being a life-long gamer, but we all had a fantastic time. There are various games set up with different type of "diggers" such as "hook a duck"; with a hook on the end of the arm, 10-pin bowling; with a mini wrecking ball on the end of the arm, tyre stacking, where you drive a weird looking machine with pincers and rear wheel steering (that one was challenging) and of course "dig a hole".
