I use this belt size 83 x 1/2 for my Husqvarna 322T lawn mower. This is the mid to deck belt. When I first got this mower the stock belts were just plain rubber and broke quickly. Kevlar belts work very well but don't rush into high grass, slow cut and your belt will last a long time. This is a articulating rider mower and quite a hill climber with ag tires. Hills are abundant in Tennessee.
