I've plowed plenty with my 40 D. I don't think it is any more or less suited. Only issue is that with a gear you just pick a gear, set the throttle and go. With the hydro, you've got to have a way to set the pedal (such as cruise control). I've typically plowed with my 2 - 14" in l (low) and rabbit. Low and turtle would be a little too slow for my liking.
I've done everything I used to do with my gear 1720, including disking and dragging. Don't worry, that hydro is meant to be worked.
