Does any know why there are so few RERs around? Basically Snapper, Simplicity and Ariens, thats it. What are the disadvantages that make them so unpopular? Rear Engine Riders seem like a good crossover choice between tractors and ZTRs, without the high price. There must be something about them that I am unaware of. I know they don't look cool, but is that it? Give me some advice, since this is one of my options. Thanks
