What is the shaft below the PTO (with the chain sprocket) for?
Looks like you got your mileage out of the muffler!
I believe the sprocketed item attached around the PTO is the chain drive for a Woods mower on a cub with a fast hitch.
In the last photo you will see the bottom half with the channels and the idler pulleys...that half bolts to the bottom of the sprocketed half.
Parts 46 & 47:
