1586/ 4630 on same sale, same owner.

There is a reason to discount both of them.  The 1586 has that “dreaded” god forsaken 6 speed transmission 🙄and the 4630 had the “pos” god forsaken 404 engine🙄.  I’d guess the JD would be bring more although if the IH was a 1086 the results might be different or closer.  Me personally I wouldn’t drop too much $$$$ on either one.  I rather the 1586 be a 56 or 88 series and the JD a 4640.

We have owned both of these model tractors. The 1586 out ran the JD by lots and it was every bit as fast going down the road

This isn’t final yet until Tuesday. Just rare someone has a JD and IH of the same size on sale together.

Same size? I'm pretty sure a 1586 would eat a 4630 for lunch. Either that or chew it up and spit it back out. Lol.....

H_ll a 1086 will chew up and spit out a 4630.

According to the Nebraska tests a 1586 should outwork a 4630. 161 pto hp vs 150 pto hp. The 4630 was not the flagship row crop tractor from Deere at the time. A ‘79 86 series IH would have technically been competing against Deere’s 40 series tractors.

  The 4630 only ran concurrent with the 1586 for around a year from late 1976 to late 1977.  So,yes the 4640 was the head to head competition most of the time that the two were built.  150 PTO HP was pretty well the maximum for the JD 404 engine.  The arrival of the 466 in the row crops was very timely.

It shouldn’t shock anybody if a 1586 or 1486 would outwork a 4630.  Thought that was common knowledge. 1486 was only 5 hp less.  IH did a fantastic job of splitting the horsepower gaps in the JD lineup.

Both tractors are about the same weight and within 10 hp of each other so I just posted this being both are on legitimate farm sale. We have a 1566 that is getting sold soon a 1586 and had a 4630 we sold in 2020. The 4630 was equal to or pulled more than the 1566. We also had a 1086,1066, 966 and more at the same time.

The 4630 will pull with the 15s maybe a bit short on power but negligible to notice.

  My understanding is that the 4630 burned quite a bit of fuel to hang with a 15.

No not really we used our 4630 to pull a 28 anhydrous setup , 20 ft offset disk and a 28 ft set of 7200 hoe drills. We used the 1566 on some of same items but we used the 4630 more. Also both were used on same 3800 JD 2 row chopper not much difference in fuel use  between the 1566 or 4630. Both were used to chop 40 acres of 15 to 18 ton per acre silage in the same general field. If I remember right they both used 160 to 200 gals of fuel to chop those fields.

Interesting.  It's just not what I have heard course most of what I have been told comes from here.  Course my actual experience reflects yours.  Not much difference unless either one has been hacked or jacked up.

We are not color blind  and will give credit where credit is due. So any times farmers and people can be swayed by rumors or other peoples thoughts. Hard analysis of fuel use and power to the ground and costs associated gives you your own judgements. And in all reality you are not going to use a 2wd 150 hp tractor for heavy tillage anymore. When you can buy older 4 wd tractors reasonably. I would love to have a 4850 mfwd and a 5488 but that is later in life.

I believe that horsepower is still the best over all measure of an engines output but especially with tractors there's more to the story than that. For example I've heard that although a 1466 and 1468 are rated the same hp but the 1466 will easily outwork a 1468. We have a JD 5065E at work that even with a little turbo will fold faster than a cheap tent in a hurricane if you try to lug it where as a 450 or 720 will seemingly never give in. That's why I like to hear real world comparisons and pretty much the reason I'm on here.

Torque does the work horsepower gets the glory….

Torque is a measurement, horsepower is a calculation.  All the torque in the world, applied to a shaft, = zero work being done if the shaft is not turning.  

Horse power is how fast you can make torque, if you will.
