So my dad gave me the old 8N he'd had for years. He's been talking for a long time now how it leaked hydraulic fluid and I figured he just had a bad gasket or something.

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
