If your original cylinders are still good, but just leaking, a seal kit is not that expensive. It isnt a very difficult job to replace them either. The original deere cylinders are probably specifically made to the application. Im not saying aftermarket wont work, but why spend so much more for an easy cheap fix to leaking cylinders? Also, from experience, the seals on the piston often are not bad, its always the outer seal and rod wiper that go bad. Good luck to your repair!
