My Kubota L3200DT with 76 hours on it shut down after running it for 2 hours using a Bush Hog RDTH60 finishing mower. I checked the fuel flow to the filter, it was fine, checked fuel filter, it was fine. Still wouldn't start. Towed it to dealer, and they tried starting it on the trailer, and it wouldn't start. They kept it, and found trash in the rail that feeds the injectors. I thought that keeping the fuel filter changed should have prevented this from happening, but evidently not. Any one else ever had this problem?
