US Patent 7306177 Cutting or crushing implement

A cutting implement (1) includes a plurality of sets of jaws (3) which cut a single length of material at a plurality of separate positions along the length of the material. A single actuation of the implement (1) causes each of the jaws (3) to at least partially and consecutively close. The consecutive closing of adjacent jaws (3) places a first jaw in a cutting configuration and a second, immediately adjacent jaw in a clamping configuration. The cutting implement (1) is connected to and actuated by the actuator arm of an excavator (9).
