ABSTRACT:
A log cutting apparatus having a support frame, a cutting arm, and first and second hydraulic cylinders for pivotally actuating the cutting arm through a cutting arc. The support frame comprises two support members and a removable linking member for easy disassembly and transport of the log cutting apparatus. The support frame includes a cutting arm housing for protecting the cutting arm in a laid back position with the cutting side of the cutting arm disposed upwardly. The cutting arm passes through a vertical during the cutting stroke. The first hydraulic cylinder works in conjunction with a cam-link, actuating the cutting arm from a retracted position within the housing to an intermediate position through rotation of the cam-link. The second hydraulic cylinder actuates the cutting arm from the intermediate position to an extended position during which the actual log cutting is performed. Furthermore, cam-link disengages from the cutting arm after actuating the cutting arm from the retracted position, and it acts as both a hydraulic retarder upon return of the cutting arm from the cutting stroke to the retracted position and as a shock absorber when the cutting arm reaches the retracted position.
