I have a 2011 craftsman GT6000, and I have just installed the 42″ snow blower and it worked great for the first 5 minutes. Then the PTO stopped engaging. It has the electric switch, I can hear a click when I push the switch in and out but the engine pulley doesn’t turn. Could battery be responsible for major trouble in PTO of my Craftsman GT6000? I would really appreciate your useful information regarding this. Get back to me with appropriate replies. Thanks.
