I'm making the reasonable presumption that the last serial number for any given year is one less than the starting serial number for the successive year. The guide as such only lists the beginning serial number for each year. The source of the data is from a farm equipment quick reference guide that's intended to assist dealers in determining the year and current market value of trade-in equipment. However, we do not know the beginning serial number in this new range. So, there are some 350C units showing serial numbers in the 700000 range prior to number 723603. Sometime during 1985, the serial number scheme was changed and the new range started in the 700000 range.

The main differences between the JD350B and JD350C are that the C went to a 3/164 CID engine from the 3/152 CID in the JD350B and that the JD350C changed from dry to wet steering clutches. Listing of serial numbers by year for the JD350 through JD350D models
