The Craftsman 185476 V-belt installed on my string trimmer with the correct tension a belt needs to be. V-belt guys is the place to get your v-belts.

Exact fit, arrived on time. Good quality belt.

Bought two belts first one last for about 15 minutes
A lot of rough cutting
Second belt used for a couple hours and still is operational
Belt is a little thicker than OME but correct length causing weed eater to operate without being engaged, but stretches out after a few minutes
My opinion, well worth it for the price
