Craftsman, Poulan, Ayp, Husqvarna Replacement Belt 144959, 138255, 130801
This was the right product but I was sent the wrong size. The belts were of good quality but did me no good because even though I gave them the correct size and part number I was still sent two wrong size belts. I did not try to send them back because the shipping would have offset the price saving.
Replacement Belt for 174368 Used on Craftsman, Poulan, Ayp, and Husqvarna
Aftermarket Belt the same size as the stock #'s mentioned at considerably less cost than the OEM belt. Use on 48" 3 blade deck. The protective cover is made of a synthetic rubber compound having excellent resistance to heat, oil and abrasion. This is the primary belt, the one that goes from the deck to the pulley on the engine.
