Anyone made a 6x6 pto for LT95?

So would this work if the diffs were centred as per Nissan Patrol and hung on a leaf spring as per a truck with the ends on the axle and being centre pivoted?
I would have thought that inter axle moment would not be to extreme and with the diffs in the centre the diffs would not move apart that much with articulation.
The concern would be making sure that the primary axle did not foul its UJ as the drive shaft would move a considerable amount.
Just a thought.

Sam,as you will be aware, there are 2 modes of articulation when referring to tandems drive bogies. there is lateral articulation that you get with any vehicle. And there is interaxle bogie articulation when a tandem set has to climb a steep bank,crest an abrupt obstacle such as a sharp hill , hummock, large log etc.It is the lack of interaxle articulation on most tandem drive arrangements that ultimately defeats them in serious cross country terrain, and I suspect is one of the reasons multi axled vehicles are rarely seen in the offroad competition scene with the exception of the heavier weight classes such as European Truck Trials.
The International AACO design I mentioned before would transmit drive through a huge amount of interaxle articulation, that in practical terms would only be limited by the chassis rails restricting the axles uptravel.
The chain driven walking beams, ala road grader that you are considering making would not restrict wheel movement in this way.
