Thanks, nope I never lug it when plowing.  This only has a straight 12 speed so the next gear is 8mph.  Also I like to have a little power in reserve for when I hit a really tough spot.  In the fall it pulls very hard all the time.

"Also, where are the pics of the 8970 plowing taken from the 4850 seat?"

I am confused by this question, did you mean it the other way around? If so, then yes they were taken from my seat.  We were both pushing hard trying to get done so I never got out when we were both in the field.  Hopefully this fall I can get some pics of it in action.

Thank you.
