The M2 has every option available just about it. It has 2900 Diesel in it, with more than enough power it hasn't pulled the engine down in the field running as fast as it will take it in. It does not have rear wheel assist's, just lug tires. We wanted something to level it out more with the larger front tires it has on it. The tires acctually tilt the front down slightly but it doesn't seem to be a problem in the field. The header has AHHC like the style Rolf has only older, but it works great.
