Walk Behind Lawn Mowers

Last spring we purchased two HU 700F lawn mowers to cut our rather large yard instead of putting thousands into a riding lawn mower and because we enjoy the workout anyhow, after about half of the summer the self propel system in the front tires seemed to be slowing, this spring it completely ceased working, i took the wheels off and noticed that the gears were made out of cheap plastic and were completely stripped, i took them into my local dealer and they said that they were not covered in the warranty because anything that can be worn down over time is not covered so they could not help me, my question is HOW ELSE AM I SUPPOSED TO FIND OUT THAT THE GEARING INSIDE MY ALMOST $900 LAWN MOWERS IS COMPLETE CRAP AND CHEAPLY MADE OTHER THAN USING THE LAWN MOWER??? this i believe is a complete flaw in your warranty system and i have made all the phone calls to husqvarna and was told that you guys are the only people that can over ride the warranty and get me the 4 replacement tires that i am requesting....

Thanks very much
