Sorry, by mistake I mentioned snapper not producing these anymore but I meant Toro. Have a friend who owns a Toro dealer and they no longer offer these, although I just noticed TroyBuilt makes one but only one deck size.
The cub cadet system is different than anything on the market to my knowledge. I currently use a Toro Groundsmaster that has power steering and turns only the back steering wheels. The drive wheels just drive and do not pivot with the rear steer wheels. I get very little tear out in the yard and with the offset deck I can almost turn around 180 degrees and meet the uncut grass like a zero turn. I know that it is an odd booger but meets my needs very well.
The longer wheelbase of those units help out with the ride. I really don't understand the appeal of a fast zero turn. My ground is so rough that speed is governed by terrain anyway. Size of deck cut to me is where I save the most time.
Mine is very rough also...these are interesting...? IS(R) 32Z Zero Turn Mowers | Ferris
