I have a method of assessing comparative firing voltage. Purchase an NE2 Neon lamp from radio shack or other. It is the size of a dash light bulb with two wire leads out the bottom. Attach a stranded 20ga insulated wire to both leads. Make one about 20" and the other long enough to go to a spark plug wire from the operator"s platform or driver"s seat. Wrap the spark plug wire with 15 turns of the 20gauge wire and tape in place with black electrical tape. Leave the end free!
Ground the other lead to the chassis.

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
