I am sure that this is not the right thread to post this in but I really need some help pricing my Exmark Lazer HP. The specs are as follows: 853hrs 23 HP Kaw. 52" Donaldson air filter. Purchased in June 2002 this is a one owner machine with new tires, belts, and 4 sets of blades. This machine is also equipped with a mulch kit. I am buying a new 60" this spring because I have recently switched over to all commercial accounts and would like something a little larger. Thank you to all who help. I really did my homework as far as doing searches on this site and nothing has come back as helpful.
