Abstract
A log processing head with a top knife and moveable feed means and delimbing and/or debarking means pushing a log against the top knife by means of actuators. In order to allow the top knife to follow the contour of the log without damaging a pin holding the knife, a pivot joint is used between the knife and the connection of the pin on the structure.

A log processing head comprising:
- a structure;
- feed means and at least one of a delimbing and a debarking means, movably coupled to the structure and adjustable by means of an actuator;
- a knife having a centerline and defining two apertures positioned on each side of the centerline, the knife coupled to the structure by receiving retainers through the apertures and the structure, the retainers being smaller than the apertures to allow movement of the knife due to the impact by a log;
- a pin coupled to at least one of the structure and the knife;
- and
- a pivot joint between the knife and the structure retained on the pin.
