I'm looking to hear some input from you equipment experts on a good asking price for a Gravely Pro Walk 36" Belt Driven. The hours will be in the 40-50 range. (Currently has 33.) Oil and Oil filter was changed at 8 hours with (Amsoil) and again at 25 hours. I have three sets of wavy mulching blades, an extra brand new air filter, and a full mulch kit installed. After taxes I believe I'm out $3,500.00 not counting the mulch kit, extra blades, and air filter. I know I'm going to loose some on the deal, but hoping not to lose my butt on it on the way to the dealer to pick up a hydro. External notes: Machine still looks brand new, I don't believe there's a scratch on it anywhere.
