MicroCut® twin-blade system uses 4 cutting surfaces to make ultrafine clippings for superior mulching and bagging. Select among 8 mowing heights from 3/4″ to 4″. Roto-Stop® blade stop lets you step away from the mower to empty the bag or clear items out of the way without stopping and restarting the engine. Self-propelled, hydrostatic cruise control transmission offers precise speed control from 2 to 4 mph, to change and maintain the right speed for mowing conditions.
