[Farmall] Super A belt pulley

[john hall]

Thanks for the info Jim. I had forgot about the big shield that went around 
the PTO shaft. I think one or maybe two of them is laying around somewhere 
under the tractor shed. They were probably removed since you most likely 
would have trouble mounting a sprayer pump with the shield on there. I think 
I have even seen one of the round ones that goes over the shaft, I'll have 
to look sometime. Both the tractors here have the flat shield behind the 
belt pulley. It is never in the way and definitely a must---I believe 
without it the operators pants of shoes could get into the belt pulley.
