Claims

[Scope of Utility Model Registration Claim] An engine is disposed on a chassis, a blade mounting shaft that rotates in response to the rotational torque of the output shaft of the engine, a disc-shaped blade attached to this mounting shaft, and a trolley. In a concrete cutter having a pair of left and right rear wheels attached to a rear shaft; at least a pair of left and right vibration prevention wheels 14 are provided on the front end 13 of the cart 2 to be in contact with the ground at all times, whether cutting or not. The vibration prevention wheel absorbs and attenuates the resonance of the blade 6 caused by the vibration of the engine 4 when cutting the concrete 29.
A concrete cutter that is characterized by preventing resonance.
