im thinking of buying this for now and buy another Z later in the spring and sell all the equipment i have now. the mower is a 52" 23hp kohlor engine with new dethatcher and trac vac bagger with 2 40 gallon bins. its hours are kinda high 2300 hours he said it was very well maintained. it has new hoses new hydro pump or pumps. i thinks thats all what do u think is a fair price for this?
