JD 420 Blade cylinder
I have a 420 that the blade cylinder seals are shot.Are these available from any aftermarket sources? It is the blade with the frame inside the tracks.

Your local JD Industrial Dealer should have the repack kit if they are original JD cylinders. Get a casting number and contact them.
My local JD ID wanted $75/hour and estimated 3-4 hours to repack one cylinder. I had never been in to one, did it in about 1 1/2 hours with minimum tools and shop equipment. Not sure what all they do in those 3-4 hours, but my cylinder now is dry as a bone, no leaks.

I rebuilt mine including replacing the rods and I got all new parts at a local hydraulics shop. The piston cups were upgraded to modern material and rod seals and barrell seals were upgraded too and I just got a peice of chromed rod material and made new rods.
