An improved concrete cutter has a longitudinally-extending primary boom and one or more saw carriage sub-assemblies that move along the length of the boom. 'Wing-like' boom extensions are hingedly secured at each end of the primary boom. The boom extensions can be easily positioned at each end of the primary boom to extend the cutting width of the concrete cutter and without requiring removal of the boom extensions from the concrete cutter. The saw carriage sub-assemblies are independently movable along the boom extensions. Carriage spacing is variably-adjustable along the boom such that each saw carriage can move toward or away from the other saw carriage. Each saw carriage sub-assembly is height-variable and is self-adjusting to contours in the profile of the concrete surface being cut.
