I would say it probably is. I have noticed that John Deere has not been building the type of quality that has served them so well in the past. Especially in the non-commerical non-industrial products. More of a name than anything these days not worth the money. Not that much better than the low end products especially in riding lawnmowers. In this market you will pay double the price without getting double the quality.
Is the lightning snow plow blade for john deere riding mowers as flimsy as the customer reviews say?
I have not seen one, but I would say that a snow blade would last quite awhile since it really isn't used that often. If you buy one that is really heavy duty, make sure your model mower can handle it.
