Abstract
A lubrication arrangement for the blade chain of a felling saw utilizes the oil in the hydraulic system which operates the blade chain. Some of the oil flowing from a hydraulic motor to a lubricant tank is fed to the chain for lubrication purposes. The feed line includes a flow controller such as a resistance valve and a directional valve for preventing oil from flowing to the tank from the chain when the saw is not operating.
