My 09 is the same as the other years, put it on it's right side in really deep snow it starts to wheeze like a 70 yr old smoker. Maybe it's my imagination, or the different setup, but the 09 seems to recover quicker, when it starts to bog a quick yank the other way gets rid of it right away. I don't remember my 07 or my 08 doing this as quick. Actually the 08 got stuck in the same spot that the 09 141 went through & it's a 153, maybe it is slightly different.
