Zil all wheel drive tractor trailer info

[Dieseldog]

I am looking for information on the Zil all wheel drive tandem axle truck/tractor with its mating all wheel drive trailer. I know there is two styles of drive systems to the dual axle trailer in one that uses hydraulics from the truck and a second that is mechanical drive with shafts and gears that pass through the fifth wheel trailer hitch. It is this mechanical drive model that I seek information on. A while back I stumbled on a Polish web site where a guy had one of these mechanical drive tractor and matching trailer and a short video of it driving in a muddy field but cannot locate it now. If anyone here can provide a link or more information/manuals/details on these unique tractor trailers I would be appreciate it. Thanks again---Dieseldog!
