Small Engines (Lawn Mowers, etc.): pto clutch bearing, correct model number, international harvester

Question
I have an 1863 Cub Cadet with a bad pto clutch bearing that needs to be
replaced. When it failed it got hot enough that I had to cut the bearing off with a
cut-off wheel and in doing so I I cut it where the #s were, not knowing that
that's where they were. Can you give me a part # for this bearing? The Model # is
CH18S - Spec# is 62509.   Thanks.

Answer
Pete, I need the correct year, and the correct model number. That model number is coming up as no such model. .......Tom
If its a old model you may have to settle for the entire PTO. Years ago Cub was a division of International Harvester. Now they are made by MTD in Cleveland, and not half the machine they were. MTD has bought out and now owns 6 past mower companys, including, MTD, Bolens, Troybilt, Craftsman, Cub, yardman, not to mention a few others.
