I have no idea, but I've always considered riding lawnmowers to be a consumable item with little value once they are used and especially out of warranty. To be honest, it seems like the prices would be all over the place. For example, I just purchased a Husqvarna 54 w/Kawasaki 24HP engine new (got a good price), but I would rather have found a used 46-50" model since I really don't have any use for the mower should we sell our house in VA. In my case, I was willing to pay $600 for a 3-year old mower in good shape with about 100-hours on the engine. That's what it was worth to me since the mower was out of warranty and I could face potential major repairs on the engine, transmission or cutting deck. In my case, I would just as soon fork-over $1699 for a new mower (especially since I know how well it has been maintained) than shell out more than $600 and deal with unknown reliability and repair issues. However, I was surprised how much people thought their 15-20 year old rusty, ugly riding mowers were worth. I remember someome asking $700 for a 38" Craftsman that was over 25-years old. Sorry, but that mower was worth $0 to me. You may want to take a Craigslist in your area.
