My tow bar connects with the lower hitch arms, like in Richards pics. It's easy to hook up to the trailer when you can raise and lower the bar and put the ball right in the trailer hitch. But it will raise up, it holds weight but doesn't hold down. What I see in the pics, is the tow bar has a connection down to the tractor's drawbar. That will hold it down for sure. Gives me an idea!
