if you go from a 6" drive pulley to a 4" pulley, you will loose 33% speed. I am not sure how it will effect tilling efficiency, but it will feel like you have more horsepower.
I have never gotten that far into tillers, but assuming it has a 100:1 gear ratio, the tine speed would drop from 36 rpm to about 24.

Would you be able to change your other pulley to offset the change? That much of a drop in tine speed would make a big difference in how fine it could till. Just a thought.
I think you could get the same result, slower travel may not be an option, so you may have to make an extra pass or 2.
I guess it comes down to: how fast you want to get it done/ how much seat time you want to get

Thanks for all the replies. It's my MF14, but I just bought a Kohler Command 18hp v-twin that i'll be fitting on the chassis soon. The PTO that I got is a 4" pulley and that goes to the tiller which has probably close to a 12"-15" pulley. I think it'll be ok, but just want to be sure. As far as I can tell, the pulley on the PTO isn't interchangeable.
