My Craftsman DLM 21 inch with Honda engine is one of the best power mowers I've ever woned.  It has rear wheel drive and rear baggs with mulcher ability.  The height adjustment is easy with one lever control.  The suction from the blade picks the clippings left on the driveway clean and baggs it.  If there is anything slightly amiss it's the way the bag empties.  There's no zipper, you just dump it out the intake front and it gets jammed easily and you have to pull the grass out with your hand.   The mower is very easy to start without having to prime it.  The pull strength is fairly low...
