Dardanelle, in Yell County, Arkansas | Can't speak of a M7 but, I have a M6-141 and every 18-24 months the DEF header has to be replaced because the concentration sensor goes out. Kubota replaced it under warranty until the last time where I was hit with a bill for over $4300.00. This is a well known problem. The first time it went out I had to wait 7 weeks because Kubota didn't have any left and they were being manufactured in Japan. This was way before Covid, they just couldn't get enough manufactured because of all the failures. (at least that is what I was told.) Other than that it's been great but.......I also bought a 5713S Massey last year because of this. |
