BOUGHT A MOWER THAT RUNS BUT DOESNT GO ANYWHERE. ITS MISSING A BELT THAT GOES FROM A PULLEY TO A PULLY AROUND THE TRANSMISSION. DONT HAVE A PART NUMBER OR MANUAL. THE NAME ON THE MOWER IS A ACE MOWER BUT UNDER THE SEAT SAYS AN MTD PRODUCT. SERIAL # 1L187H30122 AND THE MODEL # IS 13AN6986033. BELIEVE THE BELT IS A VARIABLE SPEED BELT. THIS IS A 16.5 H. P. MOTOR. BELIEVED TO BE A 1996. OH ALSO THINK ITS A HYDROSTATIC MOWER. NEED A BELT DIAGRAM TO MAKE SURE I PUT IT BACK ON RIGHT THANKYOU.
