We wanted to give it better balance so now the entire engine is 100% behind the rear axle. The engine weighs about 4000 lb., so to push it from in front of the axle to behind shifted the weight tremendously. “This layout helps with braking, too, keeping the rear wheels on the ground. We went from 5600 lb. of ballast to 1600 lb. with a 10-row head and we were able to put some of that weight savings into final Tier 4 components.” When suitcase weights are required, such as with corn, the weights go on the rear bumper.
