Help identify 2012 drive pulley setup

[4xbill 2]

When i tore down my 2012 to restore it, this was the drive pulley setup on the BGB. It does not look like the setup in the diagram. Is this an alternate PTO setup? Any ideas? Thanks

The diagram is of the clutch & brake group. the pictures are of the drive pulley that go on the bgb.

Looks like you have a the right side BGB pto pulley stacked on top of the normal 2 piece drive belt pulley. The right side pto pulley were mainly used to drive a leaf vac but probably had other uses as well.

It was also used to drive the 1500 Watt Mobile Generator

As well as the 990328 Vacuum Collector.
