You still aren't getting it, with the 3pt not being a fixed device, dropping it down under the axle means zilch, nada, as the action of pulling the load can still make the hitch rise and rotate that tractor around its axle. Remember, nothing holds the 3pt down but gravity. Pulling action and a sufficient load will RAISE the 3pt.
Its not a moot point, these posts are archived. We don't want son unsuspecting person reading them down the line and get the idea that a winch on a non fixed point under the axle is fine. Its the non fixed point that is the issue, not just the fixed winch in this pos, but the talk of a non fixed 3point one that could be a problem
