OK guys, need some help here. I have read poor ratings on tractors with the turbos and particulate filters. A lot were on 2013 and 14 models. Did Kubota have the 3350 in 2013 and 14? Anyway, have they got the problems solved with the 2015's? Most of the problems related to shutdowns due to the particulate filters. I am looking at a new one, but not real sure what to do. I have a 2011 B2620 now. I like a lot of the changes to the newer 3350. What say you guys that have a new B3350? HJT
