I bought my 184 for $2500 locally (drove it home). It had a 3-point hitch, a creeper, and a combination rear light. It also came with the 3160A mower deck and all were repainted about 5 years ago.
It did need some work shortly after purchasing. (Brakes, Clutch, Throwout Bearing, U-Joint, Driveshaft, PTO Belts).
Later on I purchased a used Model 15 Tiller for $800 and a Model 50 Snowthrower for $700.
Fixed up and Used the snowthrower for a couple of years and sold it for $800.
I have refreshed the engine with new Main and Rod bearings, new pistons & rings. (had the crank turned and cylinders bored as well)
Maybe I overpaid for the tractor, but after all this work on it, there is no way I'd sell it for less than the $2500 + $800.
Two rusty 184 tractors (no options) with 60" mower decks have been sold this spring around here for $2500 each.
This one has been advertised on Craigslist for 2500 and looks like he's dropping the price to 2000. As you can see it is in decent condition, but no options. http://flint.craigslist.org/grd/3859161188.html
