id be a bit carefull there too doing your own hoses too
many shops wont do hoses for cars etc due to insurance
I appreciate what you are saying but the load on most agricultural stuff is way higher. I've seen a hose snag on a tractor loader and rip the fitting out, the loader hit the deck from full height. Most hydraulic places don't test the hoses and if something happened I'm guessing it would be pretty hard to prove it was them who made it.
