They are Brent 740's. I've had them for 6 or 7 years. They will each haul 750 bu. of corn when very full, maybe 30 or 40 more if it weighs really good. Probably only 700 of soybeans. The new model is called a 744. Most guys around here have the 640's or 540's. Yeah, they are a little overweight on the roads.
