Abstract: A mowing device includes an elongated frame having a plurality of reel mowers mounted thereto. A drive pulley and a driven pulley are rotatably mounted to the frame and have a pulley belt trained there around. Interconnecting the driven pulley with the reel mower is a linking shaft having universal joints at its opposite ends. One of the universal joints is connected to the driven pulley, and the other of the universal joints is connected to the shaft of the reel mower. The two universal joints and the linking shaft permit the reel mower to float upon the terrain being mowed without interfering with the alignment of the drive pulley and the driven pulley.

Abstract: The blade adjustment device of the present invention is used with a sod cutting machine comprising a sod cutting blade, a sod roller positioned in close spaced relation to the blade for cooperating with the blade to sever the sod from the ground, a blade supporting frame connected to the blade and movably mounted for movement toward and away from the roller. The adjustment device comprises a power actuator, and a linkage mechanism pivotally interconnecting the power actuator to the blade supporting frame for causing the blade supporting frame to move toward and away from the roller. The linkage includes an input end connected to the power means and an output end connected to the blade supporting frame for moving the blade supporting frame in response to actuation of the power actuator. The linkage mechanism reduces the distance of movement, so that the input end moves a greater distance than the output end.
