CaseIH 600 Steiger Quadtrack with an 870 Ecolo-Tiger heavy tillage tool

Ground speed: 6.5 mph, depth of chisels: 10 in, Acres/hr: 20, Gal/Acre: 1.5, Gal/hr avg 28-30, Savings with Diesel Saver: .1-.2 gal/acre. This tractor was really getting after it even though it seems like there is a never ending layer of topsoil. It is pretty amazing. The ground was wheat stubble.
