We use our belts on a log debarker!

So far so good. The heavy duty belts I ordered were $90 OEM from a dealer. After markets from the local parts stores $55-60
But they sold me the bigger one for $11.83 and the shorter one for under $8! Only used the longer one right now but it seems to be holding up well and doing the job. I was skeptical about quality when they told me the price. Figured they had to be cheaply built but like I say so far so good. I know where my next lawn mower belt is coming from!
