I had a cylinder go bad on my old flexwing mower. Dealer/manufacturer no longer supports it (Alamo now owns company)
I have TWO similar cylinders....took one off, took it apart. Took the rod/piston assembly to my local hydraulic shop. He took the piston off, found the parts to fit, gave me a second set of them and I was almost done.
Came home, reassembled what he did for me, then took my other one apart....and promptly snagged one of the (new) gaskets so I had to go back and replace the one I damaged. Oops.
None the less.... they had me in/out in 15 minutes.
Any options like that for you where you live??
