I installed my 39" 3 blade mower deck on my 1978 210 yesterday afternoon so I could mow. I had it and the JD M47766 drive belt removed as I had the 43C center blade on. When I was installing the belt I noticed a single crack on the backside of the belt. This belt is only 3 months old. Is this typical or should I be looking at something here? The belt has always been properly routed. I hope it will make it through the rest of mowing season. How long should I expect the mower drive belt to last?
