I will get a picture later today. I think it was used for belt driven equipment that was stationary. I thought it was something that should be saved. They where chucking out lots of stuff so home it came.
Gereld This pulley was used to drive things that that were driven with a flat belt. We used ours to drive our hammer mill to grind feed and to run our buzz saw to cut firewood to length. the belt is usually 5"to 6" wide and 25' long. this was before most hammer mills were pto driven. I think I have a belt out in the barn.
You take off the pto cap on the pto. Remove the 4 bolts that hold the anti sway chains, slip the pulley on the pto then replace the bolts and you are ready to go. takes about 10min at most.Did it a hundred times
