ABSTRACT:
A motorized lawn mowing machine supported on wheels has a generally horizontal deck with a spindle mounted grass cutter blade below the deck which is rotatable in a generally horizontal cutting plane to cut grass as the machine moves in a forward path of travel. A drive spindle driven by the lawn mower engine protrudes above the deck and mounts a first pulley. Mounted on the deck for swinging movement between an extended operative position in which it extends forwardly and sidewisely angularly from said deck and a vertically raised inboard inoperative position is an auxiliary support having a vertically disposed spindle near its front end with a second pulley thereon. A rotary trimmer disc with flailing cords is mounted on the spindle to rotate in a horizontal plane. An endless drive member is trained around the first and second pulleys and power driven mechanism is connected between the deck and auxiliary support for selectively moving the auxiliary support between operative extended position and an inoperative vertically raised folded position in which the endless member automatically disengages.
