ABSTRACT:
A stabilizing mechanism for the circular saw of a felling head is provided. The mechanism includes at least one gyroscopic stop disposed slightly above the saw on one of its sides in order to prevent the tilting of the saw in the opposite direction due to the gyroscopic effect when the saw is angled forward. Gyroscopic stops may be provided on each side of the saw and be combined with back stops extending over the rear extremity of the saw.
