This sturdy pruner head is no bull! The "Bull" is meant for those bigger bite jobs that seem to slow progress down. This pruner head is built on a double pulley system for even more leverage. The "Bull" pruner is made even beefier with reinforced parts. So don't be cowed by a slightly bigger branch; give the "Bull" a shot.
Marvin's "Bull" QCB features a 1 3/4" cut, dual pulley system, adapter and 15' of 3/8" rope. The QCB easily inserts into the female ferrule of your extension pole. All parts are replaceable.
