Hello- Thanks for reading my post. I'm having an issue with my Craftsman Rider. It's an old rider so don't believe its hydrostatic. These are my symptoms. I put it in gear and it cuts for awhile but then just stops....engine keeps running and it keeps cutting but wont go forward. If I can get it to start moving again, and I make a turn, it clunks. Seems like the power is hesitating, also because I can barely make it up hills most of the time Don't know if it's something transmission related?? Thanks!
