Hydraulic Cylinders Are Awesome! But Are These Fixable?

A hydraulic cylinder on my tractor backhoe blew out, and the dealer said to just buy a new one.  No way.  I'll fix that thing for $25 instead.  While I'm at it, I patch another cylinder with a scratched rod in a way that you just aren't supposed to: welding it.  With some care and patience, I think it came out really well.  Will it last?

I also explain how hydraulics work, the physics behind them, and have a discussion on just how friggin awesome hydraulics really are!

***UPDATE:  The dealer really did a disservice telling me to buy a new cylinder.  It turns out that the backhoe on this machine is AMERICAN MADE, by a company called Bradco in Texas.  If you contact Bradco, they do indeed sell seal kits for these cylinders.  I don't think Mahindra is at fault for this, but rather the dealer who should have just said: "Hey, that backhoe is made by Bradco.  Call them."  I think the person I spoke with couldn't find info on the backhoe and so just gave me the easy answer: "Buy a new one."
