It was a longer process when the development of a new tractor was carried out. It's easier now, with 3D software and computerized machines. However, it was an honor for those who built in the past to make more quality than quantity.
I've always liked the D21. I remember as a kid, probly pre teen, when this series was introduced. We had a 190XT on our farm, in fact 2 of them; one with a cab the other open station. They were nice to operate. The D21 was head and shoulders over the 190XT in terms of sheer size and horsepower. I always thought it was very handsome and wished I coulda owned one.
4020 was a heck of a tractor too, probably one of the best JD ever produced. Interesting though that the 21 could be bought new for about $100 more than the 4020. I think PTO power was 30 hp more on the D21.
We had neighbor who ran Allis Chalmers equipment. MR. J.N. SMITH, our family was John Deere and IHC mostly due to dealer location nearest AC dealers were respectively 60 and 80 mile round trips John Deere and IHC dealers were 10 and 20 mile round trips. We had two John Deere and two IHC DEALERS in each of our two neighboring towns ...
I collect old AC ads....one is introducing the D21 with a full page picture of the man demoing the plow in this video...titled..."big power for big farming".
I agree. Imagine if that were around today, it would be worth big money. I did some searching online and found this. theweekendhistorian.com/2013/09/01/memories-from-the-allis-chalmers-proving-grounds/
@@jimsteele7108 Only if cranked beyond the factory setting of 170 hp. Otherwise it was known as a heavy pig, at least in my area. Not to mention the poor reliability of the 531 engine. Don't work them as hard as the old ads showed or you'll be dropping a Detroit repower in it.
An excellent film by Allis-Chalmers on the D-21. In what year did A-C introduce the D-21 and how many years was it produced? Thanks. - Dean from Minnesota
The D-21 was made from 1963-1969. In 1965 the horsepower was increased from 103 to 127 with the added turbo. The 1965-1969 models are known has the Series II. Allis built 1129 of the original version and 2409 of the series II For a total of 3538 units.
Early D21's had weak rear ends. The 210 and 220 fixed all that was wrong with the D21 and were bullet proff tractors unlike that piece of crap Deere put out called the 5010 then 5020 then 6030. All were dogs and if turned up in horse power then they would suffer drivetrain problems. They were a poor tractor that even Deere owners admitted to back in the day when these were being used in the field. The 4020 was a fuel drink dog too but mostly reliable though my friends with a 4020 sometimes had cooling problems on hot days pulling heavy loads. The 4020 beat the heck out of any 2 cylinder.
I think probly the JD 5010 was a close match to the D21 at around 117 hp. The 5020 came out with 133 hp. In those days there was nothing bigger than those two tractors.
The 5010 and 5020 were too heavy and sluggish. A D21 would run circles around them for that very reason. Only a turbo wakes up a 5010 or 5020 but then other problems arose like cooling and some drive line problems.
The 5010 was a mighty tractor however it did not have a cross flow head like the D21. Seems odd that those tractors were not designed with a modern cross flow system.
Used a D21 once they were. A fair tractor I guess. Problem the horsepower was over sized for the rear end. Wouldn't stand up to the power almost every model had problems on drive system
I've been around A.C. all my life and no one ever said the D-21 had rear end issues. The 190 sure did but A.C. fixed that. The D series was a very good line of tractors. The biggest issue was jumping out of gear which was caused by the operators grinding the gears.
@@awatchmanonawall6188 Early ones had smaller bull gears and pinions. Serial number 3596 and up were beefed up. Still not as bad a problem as the first year production of the 190XT.
Beautiful piece of machinery. I view these old tractors kinda like I do guns as absolute works of art.
Well said, Jeff … same for me! - Doug in Iowa
Love the way the tester stood up over the bumps.

Great video! I am an IH Farmall fan but I love any well designed classic tractor!
Same! - Doug in Iowa
I remember the D17, another good tractor!
Great documentary. Love the way those were presented.
NOT anymore 😢
My uncle still runs a D-21 on the farm in Southern Manitoba. Think it's a '68.
Those are iconic tractor's

I'm a religious John Deere man, but I believe that the JD4020, the Ford 8000, and the D21 are ALL the best damb tractors of those years.
Lol.

Good day from Ont. Our neighbor had 8000, rear end went bad, &I heard that that were noted for bad rear end , improved on 8600 Thanks
@@bradjenkins932 Don't forget the MM G1355.
Joe Bonola how about the 1066 Farmall, or 1270 Case Agri King!
I wish they would still making I drove one of them
Thumbs Up liked for you.

We had them tractors for 20 years we didn't knew what parts were
I miss the good ol days
Jd4020 87 it was great!
I am a fan of the D21 even got a scale model of one got it from toy farmer magazine
That early prototype was rather neat looking!
I agree.
Imagine if that were around today, it would be worth big money.
I did some searching online and found this. theweekendhistorian.com/2013/09/01/memories-from-the-allis-chalmers-proving-grounds/
The prototype looks like a D-19 on steroids!
D21 I one of my favourite!! The other one is 5020
Check out that 6030 if you really want to see an animal.
I have an 80' 5020, still going strong in the snow. The Kubota reverse engineer model.

@Ben Duffin The 5020 was way too heavy and a D21 easily worked circles around the 5020 back in the day.
@@SilverGleaner , interesting. Only seen one in my lifetime and it was the neighbor's up the road.
Hell a farmer could use this today!
Did anyone else notice that, that guy wound that 426 up to 11k rpms
They do that in all the videos it seems
The neighbors had wd 45s and old wc the only allis I ever owned was a b the 21 looks quite beefy.

Hi Dennis, thanks so much. An impressive piece of equipment and good looking as well.
uncle had one rear end was weak traded it in for a 4020 good tractor there

Have you ever made it to Hutchinson Minn for the gathering of the orange? If your a days drive away and bleed orange...highly recommend
Yes I've been to Hutch. I have a couple of videos on my channel from that show.

Never been more disappointed by a tractor than the 5020. Heck, the 6030 isn't terribly impressive. The 531 was not a very good design.
I like the comment below re tractors and guns being pieces of art. To me they are. Especially guns.
Man alive that’s why when I purchase things near and dear to me like guns or anything allis I don’t sell it
Hard to believe they were quite a beat cheaper $5,700 than a John Deere 4020. I wonder why they did not sell more.
We have 2 allis combines

The D-19 rear end was different from the 190 and the 190 rear end was different from the D-21.
they did have weak rear ends saw it with my own eyes

I’m going back Vv
What has happened to the days of made in u.s.a,🚜
It’s been outsourced. 😔
this tractor looks like the drawing of a 3 year old who later became a cartoonist 🚜😹🤣
Say as you will, it is a fine piece of farm equipment that works well in the fields.
I beg to differ, it looks well designed to me and the fenders especially look robust with good protection!! Would love to own one!
I assume you are talking about the prototype D21. Myself I didn't like the looks of the D21 as they were produced. Too IHish for me.
A big tractor, but partly cruel music... ;-)
