I was looking in the Wix filter site for filters for my M5400. They list two engines for the M5400, the F2803 and the V3300. My tractor is used and I bought a used manual for it from another source which says that the 4700 and the 5400 have an F2803. The larger three tractors in that series, the 6800, the 8200 and 9000 (think that's right) have the V3300 engine. What I want to know is did Kubota build some M5400s with the V3300 engine in them and if so how can I tell which engine is in mine?
