I believe they are to lock the 3pt at a fixed height. If you tow a trailer on a 3pt it can cause a rollover. When you stop, the trailer tries to keep going. As the 3pt has nothing holding it down, it will lift & the trailer raises the center of gravity beyond the dented of stability. If anything is off center, the tractor will roll.View attachment 519975
With stay straps attached as in the photo is the draw bar still able be raised without bending the stay straps? Or do the stay straps do just that lock the draw bar in place?

The "Stay Straps" in the photo lock the 3point in one position.
Drawbar can not be raised or lowered but WILL still spin.
They make a drawbar lock that keeps the drawbar from turning but it is not shown in your photo.
