I'll add to the questions.  What brand is the cleaner/scalper?  Ernie, do you have links to the manufacturer.  I have a couple versions of Snowco cleaner/scalpers but I what I see of that one.

The truck that the Brandt grain vac is dumping into serves to some extent as a meter box into the what appears to be a Wheatheart transfer auger.  The cleaner/scalper may be hydraulic drive, along with the transfer auger.  The "Versy" may have good hydraulic cooling capacity - a neigbhor had (I believe) an old Wagner with a huge oil tank that was great for running hydraulic motors.  But the Versy appears to me to be more closely aligned for running a pto driven auger than the Ford.

It is an interesting setup.
