The Tree Limb Shear attachment attaches to a Gradall boom, which gives the operator the angle to productively trim branches and limbs that extend over roadways. The low working profile of the Gradall telescoping boom also allows the operator to position the carrier and work under tree limb obstructions — something that is not possible with a conventional knuckle boom. The attachment can typically cut through large branches 8 to 10 inches in diameter.
