I was given a Cub Cadet LT1024 that was not running. I replaced the 26h B&S motor with a new factory replacement. It runs great now but the PTO is throwing sparks and smoking even without the PTO engaged. Does the PTO Clutch need replaced or does it just need adjusted? The Cub Cadet # for the PTO is 717-04080 and it is an electric PTO. I really appreciate any info.
