If you have someone to run a cart, and the combine, that speeds things up tremendously! The combine stays moving, dump on the go, combine empties, the grain cart goes to the truck!
Our cart has a scale, so we scale everything that goes on the trucks, for crop insurance needs. We don’t need a platform scale that way.
2009 was a wet fall for us, combine couldn’t get more than half a hopper before it would sink in the mud. We bought the first cart to keep the combine moving. Half hopper, unload on the go, once we had 2 half hoppers, the cart had to go unload, cause that would start sinking. So they have benefits if you have the manpower!
