A machine for cutting holes in concrete slabs comprises a connector adapted to be secured to an adapter of a front-end loader. Secured to the connector is a first frame structure that includes an elongated tube and a support foot for engaging the surface of a concrete slab and supporting the first frame structure. Confined within the elongated tube of the first frame structure is a beam that is slidable back and forth therein. One end portion of the beam extends from the elongated tube. A second foot structure extends downwardly from the one end portion of the beam to where it may engage the surface of the concrete slab. Secured directly or indirectly to the elongated beam is a concrete hole cutting saw unit that includes a drum type concrete saw. Interconnected between the beam and the first frame structure is a hydraulic cylinder that is operative to move the elongated beam and saw cutting unit back and forth between a retracted and extended position. Accordingly, the concrete saw can be moved back and forth, laterally with respect to the front-end loader. By raising lift arms associated with the front-end loader, the concrete hole cutting machine can be moved from location to location. In use, the lift arms are lowered to where the two feet engage the upper surface of the concrete slab and the concrete saw is lowered into engagement with the concrete slab and by driving the concrete saw a circular hole is cut in the concrete slab.
