  • Patent number: 5085044
    Abstract: A two blade mower deck for lawn and garden tractors having a continuous height adjustment feature. The mower deck includes a primary cutting blade and a smaller diameter secondary cutting blade. The secondary cutting blade is positioned to the side and slightly to the rear of the primary blade so that the cutting swaths of the blades overlap when the tractor moves forward. A continuous roller across the rear end of the mower deck follows the ground contour to prevent scalping or uneven cutting. The vertical position of the roller relative to the mower deck housing can be continuously adjusted by a crank handle to permit continuous adjustment of the cutting height.
