The 129 was a very popular cub cadet for IH, so if you need additional parts, they are plentiful. Congratulations on finding some really great deals and getting a 129. It will handle your towing needs and with a snow blade it will get you cleared out fast enough that you will look around and be doing your neighbors' just to try to get more seat time.....that is if you like being in the snow.
Looking forward to seeing more of your posts in the future,
Cub Cadet 123
