feller

A feller is a type of logging machine used in harvesting wood. These machines are equipped with shears, chain saws, or circular saws and are typically used for felling trees with smaller diameters, such as those used for pulpwood. Larger feller machines are capable of felling trees up to approximately 50 cm (20 inches) in diameter. Some specialized machines can perform multiple operations, such as felling, delimbing, and bucking, and are then called harvesters. Feller-bunchers are a specific type that both fells trees and piles them. The use of mechanized harvesting, including fellers, is a growing trend in forestry.1
