I have ordered these belts using information from the remaininmg old belt on my MF1655 but they are not the correct ones for my application. Aftyere researching the Snapper 1855 which is the same as MF1655, I found the correct size is 1/2" x 23". I found na set locally at a very reasonable price ands will be returning the present order as well as the previous order whioch was also incorrect..
