ABSTRACT:
A hydraulic shear attachment means for construction equipment having a support arm for pivotal attachment to said construction and a lower jaw for shearing. The arm includes flange members positioned on either side of the lower jaw to support the pivotable upper jaw. Arcuate tracks are positioned in the support flanges to receive a support pin extending through the upper shear jaw which rides in said tracks during actuation of the upper jaw.
