That is a Cub Cadet lawn tractor from the late '80's early '90's-probably a 1715. That will have a Kohler Magnum 17 vertical shaft, which will have some parts that interchange with the KT17/Magnum 18 horizontal flat twins. The seats on those are the same low back seats as on some of the '70's-'80's Cub Garden Tractors. Other knick-knacks such as the hydro knob, taillight reflectors, some switches will interchange with the GT'S. If that is a nice seat, it will be worth it to grab just for that.
