I work for a municipality that is going through some financial strains at the moment. Most of our equipment are Kubotas, but we have a moderately high use 2005 New Holland TC40DA. The OCI is every 100hrs, while our Kubotas and John Deere are either 200-250hrs. Trying to stick with the manufacturers service intervals makes my boss feel that I am changing it too often on the New Holland. Does anyone know why New Holland has half the maintenance intervals of Kubota or John Deere? All the engines in question are made in Japan. I like my job, but once or twice now I have bought out of my own pocket (and not told anyone so as to not set a precedent) to do normal oil changes when they were over by 70hrs plus even though nobody seemed to care at work that they were due in the first place. Money is tight for me too, but I'm trying to do right.
