Of the two I’d say 4630 quad range. Power shifts get to be spendy if something scatters. I spent many an hour in a 4430 picking rock, mowing alfalfa and whatnot. The 4630/40 and 4830/40’s seem cheap for their size. I guess they’re too big for some guys and not big enough for others. I also think only having the large 1000 rpm hurts for some guys.
