Abstract
A timber-working head comprises a frame, first and second delimb arms pivotally coupled to the frame, and a single delimb cylinder operatively coupled to both the first delimb arm and the second delimb arm to pivot the first and second delimb arms relative to the frame to open and close them. The first and second delimb arms are otherwise operatively unconnected from one another allowing pivotal movement of each of the first and second delimb arms without corresponding pivotal movement of the other of the first and second delimb arms. The second delimb arm comprises a cam stop defining a variable closure point for the first delimb arm, and the first delimb arm is configured to pivot into closed engagement with the cam stop.
