If you've never used it how would you know what it can do? It's the same as someone not knowing the benefits of draft control on a 3 pt. hitch. Just because you've never used doesn't mean it isn't a very useful feature to have. You didn't even know your machines have it. It clearly lists it on the 1845C.
