Replacing hyd tube under Kubota

[Boeing]

I ran over an old 8" hidden stump while mowing and it hit the metal tube leading out of my hyd pump and going to the filter. I didn't know it until I saw a puddle under the tractor the next morning. (Good thing I have a concrete floor in my shop, never would have seen it on a dirt barn or field) Anyway, I have ordered a new tube and plan on replacing it next week. Is there a NEED to replace the hyd filter too? With a "closed" system, no dirt, carbon, water or contaminants can enter. It has been about 180 hours (6 years),since I changed it and flushed the system. Thanks

While the 180 hours is not that much, given the 6 years.....I'd just go ahead and change the oil and filter

If its been 6 years since a filter change, I would change it. Note that the tube is probably going to the suction side of the filter as most filters can't handle the pressure on the output side of the pump.
