Hi I am considering purchasing a used walker with around about 800 hrs on it. How long can I expect a walker to last assuming it was well taken care of. What should I look for when going to go look it over? It is a 2001 model C with a 42" ghs deck as well as a 42" mulching deck as well as the deck lift kit and boom sprayer. It looks like it is in pretty decent shape overall with a few cosmetic scrapes in the paint and a tear in the seat. What do you think this mower would be worth? Also this unit comes with a 16hp Kohler does anybody know what attachments I could use on this machine? For example could I use their snowblower attachment? Thanks for any input. I hope that the lawn site member that has this unit for sale is not offended by me asking for others opinions on the matter.
