Mud Hogs work great on red combines, green not so good, there not balance very well, if your looking might know of where you can find used one in Mn. You must be up in northern area.
here in south louisiana not a combine sold without 4wd just make sure you track the rear wheels in the center of the front tires or the inside tire on dual wheels
Just bought my first 2166 and it has mudhog. Here in NC we have had 20 some odd inches in 34 days and it works really well on that machine. Can travel where two wheel drive combines get stuck. Also have JD cotton picker with mudhog it is a very good and relialable system.
