Now ggsteve fixing these minor items is 50% of the fun of owning older tractors. Of course leaks are probably one of the most common and the least popular issues. Sounds like yours should not be bad since it is just a hose. If you are going to have a leak having it be a hose is pretty ideal compared to other potential leaks . Of course no one likes extra expense but the work itself if fun.
You still have the Craftsman so no big deal if the JD is down for a while right?
