I have a Yard King 39 inch riding lawn mower. The model number below the seat reads C3913000 with a Code number beside it of 2052. The serial number is S001010322644. Does anyone know where I can find a manual for this mower?

Hi,
I can tell you what you have though I have as yet not even found a parts breakdown. It is a Murray manufactured in the old Noma plant. I did not try Manuals Online.
Peace,
Clarke
