Not quite a rider, but I have a one year old Cub Cadet CC 800 that I'm looking to sell. It's a multi-speed powered walk behind with a 33" deck that I purchased at the beginning of last Spring. My current hour reading is 60.1 after mowing last weekend. I have closer to an acre with a postage stamp sized house and the speed of a walk behind has proven to not be enough. I bought it new from J5 Tractor in Navasota for $1,499 plus tax - I'd sell for $1,000.
