Well, I see the simple subject caused some emotions ;-)

Relating some previous topics.

I think the Linde salesman would confirm in written the possibility of using his truck for towing, just to underline the advantages of hydrostatic transmission and brakes.

Concerning the safety issues.
I dont know what is the difference between towing dead truck with another truck and towing some trailer.
What is the technical difference (traction, brakes) between the towing wehicle with lift mast and without it. Frankly, if you take the mast off the truck you get something pretty similar to the tractor.
Some trucks even look like tractors with additionally mounted masts.
The traction and braking abilities of towing tractors and forklifts are not very different.

One more remark.
My private sedan was not designed to tow the trailers either, but when I installed a hook (and registered it) I could attach the light camping wagon (with proper mass ratio) and travel over several european countries without any legal problems.
