1568 IH or JD 4630

Which is a better tractor?
Red vs Green.

Best thing about the 1568 is now its a collectors item wasnt that great when new.

Agreed. Other the cool twin stacks it really had nothing going for it, poor fuel economy, low torque and an unreliable engine compared to the DT436 in the 1566. I'm IH through and through but to work a field the JD 4630 wins hands down.

I don't know a thing about the 1568 but I had a 4630 that I bought new and ran for 7,000 hours with out any trouble, sold it to a neighbor and I think the boys are still using that tractor. No complaints from me on that one.

I am not partial to the reliability of the 20 and 30 series JD, would look for 40, 50 or 55 series.

The xxx8 series of IH are almost impossible to get parts for, would look for a xxx6 series.

So neither are desirable in my opinion.

This is about the only situation where a jd engine outclasses the ih engine in that vintage tractor.

Not too sure what your beef with 404 jd engines are. Lots of 4020's with original engines still driving around. Have a 4430 and 4320 in the shed with original engines.

There's still a whole boatload of those 404's still out there and working. But the step up to the 466 was a giant leap.....

I agree Nick , they kept improving on a tried and true 404 and even turboed it up and still stood the test and then built the 4230 with sound guard cab and naturally aspirated, but refined, 404 for a tractor that ought to out-last any 4020. For a 95-100 hp tractor I personally don't thing one can beat a 4230. As far as the posters question, I think it's been proven that in a farm tractor a moderate rpm long stroke 6cyl is the way to go over a screaming v8 of similar size. Massey tried it ,White tried it , Oliver tried it, IH tried. Moline , Case and JD have stuck with what works and lasts.

There are 200HP 4630's out there with many hours on them and still running. That little 404 was one tough bugger. The 4630 didn't have a lot of oomph at low RPM's though. The guys I harvest with have a couple of 15000 hour 4630's that have been cranked since almost the day they were new. They have been beat and look like salvage yard junk but they still start right up and will run all day.

No issue with the 404, the other components got better on the 40s, 50s and 55s.

I'm kind of partial to FLAMBEAU Red. I still have my dad's VAO he bought the year I was born. I put many hours listening to the exhaust coming straight off the manifold. In 1967 he bought a new 430. When I bought my own farm I bought a VAO. I looked all over for a 430 but all I could find was junk. I found a great MF 135 but had to get rid of it because my partner (wife) couldn't handle the clutch. I traded it off for a green 1020. Great tractor. Easy clutch, best hydraulics and one finger steering. I also picked up a 1630. As good as 1020 but the extra HP made a huge difference running equipment. When I was forced to down size, I sold the 1020. Big mistake but it is still running great for a neighbor. JD parts are pricey but they are still available.

The 4630 was the better tractor but the 1568 would definitely be the one to own today.

Hi Randy JD tried a v8 in some 4wd tractors it was a pile of junk and parts for it are getting rare if you are still unfortunate enough to own one now. A guy i fix for had one to trade nobody wanted it on their lot including Deere. Don't know if he's still got it last time i heard it drive by it was running on 7 cylinders L.O.L.

I believe they tried a v8 twice, first in a very early 4 wheel drive, then later when they needed a 400hp one. The second was such a failure they put a Cummins in that model for a year or two.

4630!!

The tractor in question was the 8850. The engine was a 955 V8 that ran at a leisurely 2,100 rpms. They never put a cummins in them. The tractor was replaced by the 8960 which used the 855 Cummins. We had a 8850 for a few years before going to the 8960. I can show you a pair of 8850s one with close to 10,000 hrs and the other with 6,000 hrs both with untouched engines. There are still some 8850s going around here. Not going to deny some guys had problems with that engine but problems/failures are overblown most by people who have never been around one and have no experience. Also, JD never tried a V8 in any other production tractor. The early 4 wheel tractor which was the 8010/8020 used a Detroit 6-71 not a 6V71.

Hi Greenenvy
I'm guessing the problem with that v8 was quite a few guys paid for a 4wd tractor with a good HP and tried using it for that purpose. Then found that motor was a problem. It's kinda like round here the MF 1135 and 55 series tractors blew the rear ends out, and have hyd issues. Tell a guy thats never left a small southern town, and he'll tell you you are an idiot. The difference will be the 30 he knows of that have never been a problem have never worked real hard in the field cultivating or seeding with duals on, and have been babied making hay, or have real low hours on against the 20 I tried getting used parts from to fix mine,That were all junk for the same reason.

The jd v8 tractor Kevin had was never right from day one he got it, There was another guy to tried trading one from about 12 hours drive from here with dealers in this area, nobody wanted that either. The NH dealer i worked for managed to find parts to fix the one they traded in that puked getting it off the truck. It near bankrupt the sales department in what it cost to fix. 15 years ago there was only one new block left for that motor from what JD told our guys, and some other stuff was hard to find. There was another one very close to here misteriously caught fire after it had been to the repair shop to.I bet that wasn't any good either L.O.L. Every company has a memorable screw up once in a while Maybe that was JD's in the 4wd market.

We had a Versatile 976 that was problematic from the start. Those are suppose to bullet proof. I had one neighbor loose the engine in his NH 9882 and another neighbor loose the engine in his CIH 9380 on the same year. Both were around the 5,000 hr mark. Anybody can punch out a lemon on any given day.
