A shear attachment is presented for use with different types of motorized vehicles and is generally provided with an upper cutting jaw, a lower receiving jaw and a plurality of teeth along the upper surface of the lower jaw to grip an object while it is being cut between the upper and lower jaws. A single actuator may be used to move the cutting jaw between open and closed positions. The shear may be pivoted about a horizontal axis with respect to its mounting bracket to facilitate cutting at different angles. The shear is removably coupled to the vehicle using a universal hitch. The efficient design of the shear makes it durable, inexpensive to manufacture and easy to operate.
