    345 Lawn Tractor

    My 345 is leaking (small hole) out of one of the aluminum tubes under the tractor deck. Can I replace just that tube or do I have to replace the entire assembly? Any instructions as to how?

    I would guess some people would call them Aluminum tubes. The true term is hydraulic lines, and there is a 90% chance a "O" ring(s) is the culprit that is leaking. There's always a chance the hydraulic line got bent somehow and formed a crack. First thing to do is clean all grass clippings and any dust/dirt under the tractor and inspect where the leak is.

    I think there is about 13 or 14 "o" rings on the 345 and in various sizes.

    Hopefully it's a line.345's are known for leaking out the top of the tranny.
