摘要:
A connector for use in as a third point connector for a tractor has a hydraulic and pneumatic chamber for providing an easy method to adjust the length of the third point connector to thereby change the angle between the tractor and an attached implement. When a release valve is opened, the two sides of the connector can be moved towards or away from each other as air enters from the environment or exits as needed to balance the pressure inside the connector. An induced air pocket in the hydraulic chamber allows for a slight cushion against the forces as the incompressible hydraulic fluid prevents larger swings in the length of the connector. One or more of the opposing ends may have threaded connectors to allow for general size changes to the connector.
