Martin I don't have any experience with the new models but I just left a place that we had two of the 245 magnums with auto steer. I loved them you just have to be sure that they are weighted right and that you have the heavy duty front axle if you are going to dual the front. they had good power and parts are readily available. although if you have hard ground I would recommend the 275 or pur a power chip in the 245 it brings it up to a max of 318 horse at the engine. hope this helps
