Mid-Mount Mower Help. Is the 6ft belly mower model that fits a JD 4115 and a JD4310 the same one?

Need a belly mower for a JD4115. Found one that is off JD4310. That one has this number on it and it is a JD # TC 4272X011560. Does anyone know where one is for sale used that fits? We are in Lansing, MI. Thanks
