I just bought a 4440, I've had several 4430's and still have one. Will I notice much difference? If you are looking for a 4430 I'll have one for sale here pretty soon. Thank you.

Charlie-Can you tell me the hours on the JD 4430 Please? Is it quad-range? Tires? Paint? Overhaul, Trans? Hydraulics? Sheet metal dents? Price? Where in Mizzo are you? I am in Ottumwa, Iowa.
Thanks,
Jay
 
I believe the 4440 is on the old 4630 frame so to speak. Believe they also changed the engine but not sure. It should be heavier than your 4430
 
466 cid engine in the 4440 has better low end torque than the 404 cid in the 4430. The 4440 wasn't nicknamed the "Iron Horse" for no reason. According to Tractordata the 4440 is heavier than the 4430.
 
Well I have had a couple 4430's and still use one for spraying and haybine. I have had two 466 engines one in a 7720 and another in a 4450. The only thing I truly noticed with the 466 is that my fuel barrel empties faster keeping fresher fuel on the farm. Running a large rd baler with stock 4430 synchro took 4.5 gal/hr. 4430 with intercooler and running 160+ would run the same baler for 3.5 gal/hr. 4450 stock would use 6 gal/hr. This past year we had the turbo speeded up and installed an intercooler on the 4450 and that dropped the fuel to the 4 gal/hr range. I seen a 40% increase on the combine fuel costs when we went from the 404 to 466. The newer engine does start easier if the 404 hasn't been updated with new style pistons.
 

Although my 4255 with 6076 isn't classified as a 466 but it is uses a lot less fuel rd baling with a JD 467 baler than any of your tractors. But I only run my 4255 @ 480 rpm pto speed.
