Snow Blowers

I RECENTLY PURCHASED A NEW HUSQVARNA ST230E SNOW BLOWER FROM LOWES. I PAID $1400.00 FOR IT. TWO WEEKS AGO I USED IT THE FIRST TIME. I WAS BLOWING LIGHT NOT. I HEARD A POP COME FROM BETWEEN THE ENGINE AND THE AUGER HOUSING. MY LOWER AUGER DRIVE PULLEY HAD BROKEN AWAY FROM THE IMPELLER DRIVE THREAD WHERE IT CONNECTS VIA METRIC THREAD. I HIT NOTHING. IT JUST SNAPPED OFF DURING NORMAL USE. MY SNOW BLOWER IS RUINED. I LOOKED AT THE PULLEY AND SNAPPED THREADED...THEY LOOK LIKE THEY ARE MADE OF POP-METAL. WHAT ARE YOU GOING TO DO FOR ME? THANKS FOR YOUR TIME.
