well, i bought the Hustler Super Z last year at the end of the season. got a good price and have < 15 hours on it at present but it is cutting horrible and i wonder why? some people don't like hustler and say they cut awful. the dealer says this is the best cutting mower he sells and he sells kubota, lazer and a couple of others. i have bahiagrass and swapped the blades when the original pair became slightly dull. the fusion blades are on the mower now. i also greased the hubs and added air to the tires. the pressure might be a over 8# since the air gauges don't really do a good job of indicating low pressure. it is just not cutting as well as it did when i first bought it. it skips over grass and lays the grass down. it seems as if the hub bearings are all bad. how can this be? i hate it that i have spent so much money on this mower to cut my property and others around me now have a better cut. am i doing something wrong?
