See the thread below. Follow Sam Mac's link and you should be able to find the pulleys you seek. Just take measurements of the ones you have and order accordingly. I know for sure the large pulley can be found there. If your pulleys are tore up too much, I can measure the ones on my #2 tiller when I get home and let you know what size you should look for.
