Abstract
A system for controlling a felling saw in a forestry machine, the felling saw being driven by a hydraulic pump and saw motor circuit. The system includes an instrument for measuring a rotational speed of the felling saw and generating a signal indicative of the rotational speed, a calculator for calculating a power consumption of the hydraulic pump and saw motor circuit adjusted as a function of the signal indicative of said rotational speed, and a controller for adjusting hydraulic settings of the hydraulic pump or/and saw motor circuit based on the calculated power consumption. A method for controlling the felling saw is also disclosed.
