Just 1 hose has a little rubbing on the rubber part that goes through the guide hooks. I just want to be prepared if I have to replace it in the middle of a snow storm. I live close to a dealership/ hose shop but I’m not entirely sure how I would describe what I need over the phone.
Go to the Messick's ( PA Kubota dealer ) website, and look at the parts diagram for your tractor.
You should be able to find a Kubota part number for the hose you are concerned about.
Then order it from your local dealer.
Take it home, and check it by holding it against your old hose.
Hydraulic hoses are very tough, so it is likely that your hose is still OK, but I do understand your desire to replace it.
