Belt size for 1650 mower drive?

Mon Oct 04, 2010 8:59 am

I inherited a 1975 1650 Cub Cadet. I've restored the mower and deck, but I need to know the drive belt size for the clutch to deck. The deck is a 50GT model 359 and the mower has hydraulics. I have about a dozen belts that came with the tractor, but not sure which one will fit.

Thanks,
Tom Evans

The stock belt is a # 490489R2.....3/8 X 80. Since you have a #359 deck, the center pulley needs to be changed as its setup to run a B (5/8") groove belt. The stock belt may not work on the deck without the right pulley.
