Abstract: A concrete cutting machine includes a motor, a pivot arm, and a concrete cutting chain assembly. The motor has an output drive, and the pivot arm has an input coupled to the output drive for receiving power from the motor. The arm is configured to pivot relative to the motor, and the pivot arm has a pivot arm output. The concrete cutting chain assembly is supported on the pivot arm and has a power input coupled to the pivot arm output. The chain assembly is configured to be pivotable relative to the pivot arm.

Abstract: An interchangeable concrete cutting chainsaw cutting assembly adapted for installation upon a drive assembly in exchange for a removed, different type cutting head assembly. The chainsaw cutting assembly includes a housing that has fasteners that releasably attach the housing to a drive assembly in an installed configuration. A ration transmission has a plurality of interconnected rotation member, each rotatable member having a mounting shaft positioned at a fixed location on the housing by a bearing assembly. The driven member has a receiver that interconnects with a driveshaft of the driver assembly in the installed configuration whereby the driven member is rotated by the drive assembly. The cutting chain drive member operatively interconnected with a drive sprocket whereby rotation of the cutting chain drive member rotates the drive sprocket. The chainsaw cutting assembly is pivotable relative to the drive assembly.

Abstract: An interchangeable concrete cutting chain-saw cutting assembly (500) adapted for installation upon a drive assembly (112) in exchange for a removed, different type cutting head assembly. The chainsaw cutting assembly (500) includes a housing (703) that has fasteners that releasably attach the housing (703) to a drive assembly (112) in an installed configuration. A ratio transmission (525) has a plurality of interconnected rotatable members (533, 535), each rotatable member (533, 535) having a mounting shaft (641, 643) positioned at a fixed location on the housing (703) by a bearing assembly (640, 642). The driven member (533) has a receiver that interconnects with a driveshaft (372) of the drive assembly (112) in the installed configuration whereby the driven member (533) is rotated by the drive assembly (112). The cutting chain drive member (535) operatively interconnected with a drive sprocket (707) whereby rotation of the cutting chain drive member (535) rotates the drive sprocket (707).
