While searching for a second hand Walker, I have been offered to buy a brand new one at a good price (about 35% off the normal price). It's a showroom model, with zero hours, but built in november 1996! It was never sold because everybody wants diesels around here. It's a 16 HP model, one cylinder, 42GHS, no handbrake, and springs at the rear discharge door instead of shocks. Could anybody give me some advice about this model (weak points, necessary updates); and, if I buy it, should I change the hydro's oil ?
