Abstract
A pulley system for transferring motor torque to a cutting blade assembly is provided. The system is installed on a log cutting machine. A motor of the log cutting machine is positioned on a support table, which is intended to raise and lower during operation. The cutting blade assembly includes a cutting blade member for cutting a log off a tree trunk. A chain is attached to a cutting blade member and the support table, such that when the cutting blade member is driven downward towards the tree trunk, the connected chain and support table are lowered assisting the actuation of the cutting blade member via the pulley system.
