cant really tell from the pile. spread them out and see if that helps. --dont see a drive pulley
Got a couple here one was on Deere H -- complete but it has WAY more stuff on it. also have one on AC- B tractor here in the shed. Could take a pic of it to compare or eliminate My 140 has the 42 on it so that would be different probably. could take pic of the drive unit on it. Might be close to same.
