I've got a Mini Z 19/42 that I've had for about 3 months now and to say the least I'm not impressed with the cutting capabilities. It keeps leaving uncut pieces of grass all over the place. I talked to the dealer and they suggested a set of gator blades and guess what...no better. So they talked me into a mulcher kit and wavy blades, and still no better. So now I've got $160 in equipment I really didn't need and it still cuts poorly. HELP!!!!!
