Abstract
A tree felling head including a gathering arm and a bunching finger. In various embodiments the bunching finger may include inner and outer arms pivotally coupled together with the inner arm also pivotally coupled to a frame portion of the felling head. A biasing member, e.g. a compression spring, urges pivotal movements of the inner arm toward (and/or away from) the accumulation area of the felling head. An actuator connected to the outer arm reciprocally helps urges movement of the finger into and out of the accumulation area of the felling head. In various embodiments, a coupling of the actuator to the outer arm permits folding pivotal movement between the arms when retraction occurs and a tree inhibits outer sweeping movement of the outer finger. Said folding resulting in withdrawal of the outer finger from behind the inhibiting tree.
