I went to the shop this morning to find my l4400 Kubota is leaking hydraulic fluid. I traced it to the join at the main tractor casing to a crooked metal pipe of which I do not know its correct name. Any help in terminology so I can discuss the problem with my dealer (who is about an hour from me) using correct terminology. Also any opinions of the severity, complexity, etc. of this problem would be greatly appreciated.

looks like the pipe got hit and is kinked, Missing paint in one shot and the filter also has a scrape mark. you may get away with just replacing the pipe but I would compare with what a new one should look like before doing anything else.

how is the pipe connected to the case. the banjo bolt on the other end (some kind of valve ) may have rotated but the fitting at the case may have cracked at the brazing.

I definitely think I got a stick wedged in there and broke the connection at the casing. What is that pipe correctly called?

Thanks! Finally found it! Looks like the comp pipe return. No longer sealed at the o-ring entering the casing probably from a wedged stick moving that pipe.
Looks like 5-6 weeks backlog for repair at the dealership.

looks like a fairly simple repair if you are machanically savy, Once you have the part in hand of course. You may need washers for that banjo bolt connection no sense doing all the work only to find out it still leaks.
