Are you talking about a "suicide knob", if not what is a crazy wheel?
I'm not sure but doesn't DBEST run something like that - I might be wrong!Crazy wheel is what some Beeks call the fifth wheel mounted on a skid steer loader for stability.
It picks the back two wheels up off the ground so it drives like a zero turn lawn mower.How does it keep a skidsteer from tearing up ground?
