Abstract

A timber-working device (16), including a pair of pivoting delimb arms (26a, 26b), and a pair of pivoting drive arms (28a, 28b). The timber- working device (16) includes a first angular position sensor (112) configured to output a signal indicating an angular position of at least one of the delimb arms (26a, 26b), and a second angular position sensor (114) configured to output a signal indicating an angular position of at least one of the drive arms (28a, 28b). At least one controller (102,104) is configured to receive the signals indicating the respective angular positions of the delimb arm (26) and the drive arm (28), and correlate the angular position of the delimb arm (26) with the angular position of the drive arm (28) to determine the number of stems currently grasped by the timber-working device (16).
