ABSTRACT OF THE DISCLOSURE A visual feed control assembly for carriage-fed, electric motor driven sawmill saws comprises in combination with the elec- tric drive motor of the saw electric circuits including first and second trip current relays with associated first and second elec- trically operated lights or other signals. The trip current relays are preset, the one to operate its associated signal at a predeter- mined minimum saw motor amperage load and the other to energize its associated signal at a predetermined maximum saw motor amperage load. The signals enable the operator to adjust the carriage speed to suit the saw so that the saw operates at maximum efficiency at all times, irregardless of the size and character of the logs being sawed.
