Question

How do I figure the tonnage in 5 ft x 5 ft round hay bales?

Answer 1

You could weigh a few of them, then assume most coming out of the same field would be about the same. load some bales on your truck or trailer, get it weighed at a grain scale, unload them and weigh your empty truck/trailer.
