If you intend on using it for speed and offroad you will need a 1:1 ratio. A 6" rear and front pulley would be great for that. Otherwise if you go with anything over a 1:1, like a 2:1 or a 3:1, you will need to do more extensive mods to have good belt tension and reinforce the mower body, as well as redo the entire steering to handle speed.

Go with a 1:1 if you dont want to do the work or if you want multiuse.
