Well started the rider a couple weeks ago, all went fine. When I engaged the "clutch" for the blades the motor started coughing out piles of white smoke, ran roughly for about 20 seconds then shut down. I was able to start it again but same thing when engaging the blades. I do not think (???) I seized the motor because it did turn over again before the issues started. Any ideas? I'm thinking like maybe I smoked the whole clutch mechanism that runs the blades or something? I think it's going in today for checking. It was blowing massive amounts of thick white smoke is that typically a tell-tale sign of something?
