Paul, thanks for the reply. My original post was to flush out other Antonio Carraro 4400 owners out there in TractorByNet land. I bought my Antonio Carraro from a fellow down in Florida and had it brought up to NC two months ago. Cute tractor with some neat features. My tractor has a sick hydraulic system and after messing around with seal softening stuff, I've been able to get the leaks slowed down somewhat. The problem appears to be a shot hydraulic pump as the lift and steering is still much slower than it should be. The steering is done by means of a gerotor valve supplied by the same hydraulic pump that works the lift and remotes. Replacing the tractor's Lamborghini hydraulic pump will be a winter-time project.
I got the Carraro to use in cutting grass on step hillsides. It is a stable and nimble tractor. The nearest Carraro dealer to me is up near Charlottesville, VA which is about a 3.25 hour drive from where I live in NC. Will be buying parts from them and, if it gets too hard for me to fix, I'll get some local tractor whizzes to fix this little Red tractor. I have a shop manual with excellent step-by-step instructions, so it looks like we will be able to keep this baby running. I talked with an orchard operator who uses several Antonio Carraro tractors and he said they were reliable tractors and his help likes them.
