Adding weight.
 

I keep hearing that adding weight to the rear of a cub is'nt a good idea unless it's wheel weights or loaded tires. I know that using a weight box or suitcase weights adds stress to axles, seals, and bearings but, how many times have you actually seen it damage anything. I'm talking about 200/300 lbs. Would it be any worse than a tiller or a york rake?
