Jameson Big Mouth Double Pulley Pruner with Adapter and Rope

The Jameson Big Mouth pruner is a pole pruner head with a wide jaw and a double pulley for extra cutting power, sold with a pole adapter and pull rope. It is aimed at ground workers who want to cut thicker limbs on a pole without switching to a saw.

More bite, less pull

A pole pruner makes clean cuts on limbs above your head without climbing. The Big Mouth has a wider jaw than a standard head, so it takes thicker wood, and the double pulley multiplies the force on the rope so you are not hanging off it to finish a cut.

With the adapter and rope included, you just need poles. Find poles and other heads in pruners and loppers.

That extra capacity means fewer trips back to the truck for a pole saw when a limb is a little too big for a standard pruner. Pruner cuts are also cleaner than many saw cuts on small limbs, which matters for good pruning practice on ornamental trees and street trees.

Use and upkeep

Set the jaw fully over the limb and pull smoothly. Stand to the side so the cut piece does not drop on you, and wear a helmet and eye protection. Keep well clear of power lines.

Clean sap off the blade, oil the pivot and pulleys, and check the rope for wear and fraying. Replace a worn rope before it breaks mid-cut, and sharpen or replace the blade when cuts start to crush rather than slice.

Keep the rope coiled and out of the way while working so nobody trips on it, and keep it clear of the cutting head when storing the pruner.
