Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi my name is***** will be glad to assist you in this matter. give me a few moments to pull the Diagrams so I can view the parts
Sorry for the delay. You say both drive belts are on and in good condition? also check that it has not slipped off an idler pulley in the middle of machine. check that no pulley is smooth or shiny in the groove also, as this will allow the belt to slip
Looking at the diagrams, and also the machine I have in my shop currently, the only other drive issue would be transmission issues. Let me check any/all Troy Bilt service manuals for issues.
One thing comes to mind, is the Splined pulley on the transmission shaft. It could become stripped out and not turning pulleys. It is #26 in the pic
