I purchased a Husqvarna zero turn 54 inch cut Model RZ5424 / 965881301. I am very satisfied with the performance except after 6.8 hours of operation the blades are completely worn out. Out of the 3 blades only one still has the fan attached, the rest are missing. The deck is set at the mid range and the cutting height is about the same as I normally cut. Having to replace the blades after only 6.8 hours of service is unsatisfactory! I am operating the mower with the throttle wide open as directed by the manual so I suspect the blades are turning at a high rate of speed. The deck is set in the mid range as far as height. What am I doing wrong as I am sure the service life of the blades is much more than 6 hours? Is there a heavy duty blade that I should use?
