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 dont be cowed by a slightly bigger branch; give the "Bull" a shot. Marvins "Bull" QCP5 features a 1 3/4" cut and adapter. The QCP5 easily inserts into the female ferrule of your extension pole. All parts are replaceable.
