A reel mower has a drive and mounting system for easily and quickly installing a turf grooming attachment. A pair of bearing supports on opposite sides of the reel mower frame provides laterally spaced stub shafts between which the through shaft of the attachment can be nested. A pair of identical clamps releasably couples the opposite ends of the through shaft of the attachment to the adjacent stub shafts. Installation and removal of the clamps is sufficient to install or remove the attachment without requiring disassembly or lateral movement of the bearing supports or of the stub shafts rotatably journalled therein.
