feller buncher
n.— «Along a 9.5-mile corridor between Buchanan and Millwood, a team of contractors was busy removing oaks, birches and other trees to create a quarter-mile clearing. In one clearing, a feller buncher—a kind of bulldozer with a giant claw in front—grabbed the trunk of a black locust.» —“Along 240 Miles of Power Lines, Preparing Every Tower for Winter’s Wrath” by Ken Belson New York Times Nov. 10, 2008.
