Hello everyone, I am in the market for a new used mower or tractor and am intrigued by the Kubota F models. There is a used F3080 not to far from me with 900 hours , a 72 " front mounted deck and powered by a 30 HP three cylinder D1305 engine. According to my online findings these were produced between 2008 and 2013. My question is I am not sure when the particulate filters started being used. I feel I should be "safe" with regards to avoiding emissions issues but am not 100% certain. These F model machines are expensive new and depreciate significantly perhaps presenting good value to the discerning suburban grass warrior. Thanks for your help.
