Todd,
There is a double pulley for the 44 which runs the power steering unit from the generator pulley. I only have one parts book here at the house so I can't say for sure if this was a factory or after market option, here are some pics. I have seen several salvage tractors with these on them. If you can't find one let me know, I may be able to sell you this one but need to check the 44 I have torn down to determine whether I need it.
Good luck,
Jeff
