Hahaha Rob,

Just noticed your new avatar picture, I remember the old channel 19 very well.

I knew some blokes over the years that could not load a truck or even use a spacebar.

They are definitely out there.

Just keep your eye on the weights that the scales tell us.
1 The WDH reduces the total weight born on the tug wheels. This is simply because it reduces the down force on the tow bar by its lifting action.
2 The van wheels now reflect this reduction by an increase in weight. That means that there in no overall increase in van weight.
3 This same lifting action also reduces the weight born by the rear axle of the tug and increases that on the front axle.

That is all very well when stationary Alan , but when the rig moves everything changes

I think what everyone may be missing is the wdh is not a fixed bar

it is a moving flexible gizmo ,so the ball weight has to be still there or the rig would not be stable

don't laugh :):):

Alan,you are so far lost in the WDH wilderness that I fear for you.Many times,both on the forum and by PM,I have explained to you the workings of a WDH,but still you do not,will not,or cannot understand that a WDH does NOT change towball weight...EVER. To refresh your memory,I have included a screen shot of a PM I sent to you on May 14,2020.Because we have not heard from you of late,I thought that finally you understood the facts. Apparently not? Cheers

Hey Yobarr,

Has the tow ball weight remained the the same on the Olds Toronado and van picture I posted yesterday?
If it has then why isn't the rear of the car dragging on the ground?

Regards

Rob
