I love these old tractors. My "old faithful" is an International 404 gas that was made in the 50s. The hydraulics are driving me nuts. It only works when it wants to. It might lift 5 times straight, or only once per day, or less. When it lifts, it lifts strong and fast. It is full of fluid. I now have it running without a filter. I have ordered one three times, and the local IH counter can't get me the right one, and I no longer have or remember the old one. I rebuilt the engine in the spring of 14. It runs great,other than the hydraulic issues.
