What's the differences between a Brent 600 versus a 640 grain wagon. The only things I've noticed during a quick inspection was that the 600 had large flotation implement tires instead of the 22.5 truck tires, and the 600 doesn't have the little windows on the sides of the box.
Are there any others that I didn't see? How much less should a 600 be worth?
