Hunter, don't get me wrong. I love the M11. The power and torque characteristics of the engine make operating the combine a pure joy. It just likes its fuel. I had an l2_no hydro before I got this machine. In similar wheat, it would cut from 2 to 3 acres on a gallon of fuel. The R72 makes 1.33 acres_gal. on its best day. Of course, the reduction in losses because of better threshing and seperation more than make up for the increased fuel use, but as previously stated; the R72_M11 combination is not the stingiest fuel user out there.
