How to bleed off hydraulic cylinder on a tractor

Release the air: If you’re bleeding a cylinder, partially close it, but open the bleed valve on top. When the valve starts leaking hydraulic fluid, the air has been bled from the cylinder. Bleed the farthest lines or cylinders first: Whether you’re bleeding a cylinder or hydraulic lines, always bleed the farthest ones first and work forward. This allows you more space to work.

Bleed the Farthest Lines First – Start by bleeding the line farthest away from the pump and work inward, with the lines closest to the pump being bled last, and only bleed one line at a time. Keep the Reservoir Filled – Make sure to keep fluid in the reservoir; otherwise, if it runs out, you will only be introducing more air into the lines and will have to start anew.
