Possibly, the belts could be too tight. If they were too loose you would likely either throw a belt or hear a loud screeching noise when turning hard left or right. The belts should have approximately 3/8" play with moderate thumb pressure on the middle of the longest stretch of the belt. Possibly too they are the wrong belts. With dual belts, generally the thin style belt is used. Make sure the top of the belt is below the upper ridge of the pulley. Also, I like Gates belts. They are quite durable in my experience, for everything from lawn tractors to roto-tillers to automobiles and go-karts. Finally, check to see that the pulleys are aligned. If the pulleys are not parallel and on the same plane, the belts will wear out prematurely. You could have a bent bracket or a bolt with too many washers on one side. Also, often a belt that is too tight can distort the pulley alignment.
