$23,586.00 is full list (but not destination and setup) on a 4310 MFWD, eHydro, R4s, and 430 with std. bucket and DSCV. You should be able to get 15 to 23% off that, as well as some kind of promotional money.
Many dealers seem to want to quote high and work down. Many customers must like that, as well. I work in a car dealership that is a one price (priced low to sell) place. There are lots of folks who complain when they won't go lower, never mind they started out at the right price...
There seems to be a lot of whatever is affecting your dealer up there in the nor'east. Must be the water...
I would get on the Deere site and do a dealer locate and see what dealers are in a workable distance (it isn't a good deal if you can't get service...) and request quotes. You can also work up the machine on Deere's configurator and request a quote right from there. Tell them you are going to buy. And let them know that you know the list price, and ask what kind of discount they can offer.
Don't try to beat them out of every penny. Your dealer needs to make money to stay open, but you don't need to put his grand nephew through Harvard, either... In your region, List Price may be the best you can get. That may still be better than getting one from way off and having problems...
I got a great deal this way. With the Dealer locater I found a dealer in a small town just over the state line. They wanted my business to get their quota, but are close enough for me to use for service. I would never had known about them without the locater.
