Good condition hydrostatic garden tractor (believe 1973). Includes K532s Kohler 20 HP engine, 54" mower deck (18071), 54" Hydraulic lift/tilt front blade (18085-02), 33" tiller (18093), rear wheel weights (16167), front tires 18-8.5x8 (with tubes inside) , rear tires 26-12.00x12. Well cared for but some surface rust as it has never been repainted.

Thoughts on what is a reasonable selling price and what should I minimally accept?
