Looks like a thingamajig to me.
Weight for the front of a tractor.
Well, it would have to be a mighty small tractor! :lol:
well I have a friend who pulls (tractor pulls) with a garden tractor, that could be a weight for one of those. is it heavy?
could also be a weight for a smith machine style weight set up. the plates on the machine go up by 10's in order to get 5 pounds on it you slide a weight on the cable
