npelzer, look where the cab is on the MFWD tractor and where the cab is on a typical big 4WD. If you are doing row crop work, a lot of hooking and unhooking, and 3 point mounted work, the MFWD works better because you are able to see MUCH better. The MFWD tractor is shorter and will turn shorter, although with the duals on the front axle the turning radius gets larger.
However, in the picture shown the tractor is working wheat stubble and in non-rowcrop applications a 4WD is tough to beat. The drivetrain on a 4WD is a little more 'busy' with driveshafts running from the front half to the back half. I used to farm in NW Kansas and had the choice between a 2WD and 4WD. I chose the 4WD every time for working summerfallow ground.
