Riding Belt

The mower is a Montgomery Wards 26 "W cutting deck riding / pull start (model # TMO 3E4508A D201G) and the blade drive belt is missing. Does anyone know where I can find the right size and number of the belt I need? I was looking for two weeks.

Ward's outta business .... Sears and my power to get it.

too! go to your local center to refuse landfill /!
Sometimes, these guyz may be able to call your cell "IF"
This is your share! provide some money to find .....

If you do not have the old to compare sizes, you can take your mower on a lawn and a garden center, so they can measure for a new belt. I guess that neighborhoods have not had one?
