[quote="Jesse Knapp"](quoted from post at 17:05:51 07/14/18) I recently bought a 65 John deere 4020 that has sat for 13 years and we got running today. I have no steering or brakes. Not sure about 3pt. hitch as the cable is set up in the down possition. Any chance it could be something simple? All new. Fluids and filters, the filter housing filled with oil immediately after starting. Is there such a thing as air lock?[/quote]
I have a propane burner 4020 of about the same year. I am not a real mechanic, so I struggle with trying to keep things going. On my tractor, there is an auxiliary valve behind the steering wheel console, and above the starter, which is right in front of the clutch pedal. I'm thinking that the valve interfaces with the steering and possibly the brakes. It is possible that during 13 years of sitting, the valve may be hung up in a wrong position? My valve is leaking hydraulic fluid onto the starter and exhaust manifold, and I am hoping to post a question about repair kits for this and other significant leaks I am seeing. There is also a lever to the left of the three-point lift lever which must be full up for remote hydraulics to work, and the steering and brakes are not dependent on its position, but something may be hung up there too? Good luck with your efforts.

I�ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. 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
