fergiconst , Is the engine running good and strong and are you engaging mower and drive when close to full throttle? Check that all the safety switches are working correctly, it is possible the seat switch is bad or loose plug/ bad wire. Also if battery weak or charging system weak/faulty the clutch will stall out engine, charge battery up with charger and try. Check for binding in the belts, spindles, idle pulley, anything that moves when the belt engages, ensure all turns freely. Find below link for your manual as it may help and link to testing safety switch. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.

If you’re battery and belt pulleys are good then check your spark plug mine was having a misfire once you would put to much strain on mower hint turning PTO on
