What size belt to run this deck

[multihobbyguy 35]

Since my tractor was changed to a different pulley setup how would I go about figuring out what type of drive belt I need to run the mower deck? Thanks in advance, Chris.

Once you figure out your belt size how are you going to keep it tight,Rick

Also with that larger pto that deck is really going to spin about twice the normal speed,Rick

I am not really sure how to keep it tight. I was told in another topic about the tractor that the pto is a upgrade from wheel horse. Maybe someone has a instruction manual about the setup.

You could install a spring to keep tension on idler pulley to keep belt tight,Rick
