Brilliant thanks for posting- I drove the 8440 during the 90's

[@bigtractorpower]

Very cool. An 8440 is a nice 4wd.

[@mikekuchinski1086]

Very good tractors

[@davidanderson1918]

I worked the 8640 but also rebult the the transmission in that beast. Took 4 weeks to complete.....but in the end in was tearing up the fields

[@gonerydin4225]

Thanks for the history. I worked at Deere in Waterloo from '72 to '06. M Foundry, Electric Foundry, Engine Works and Drivetrain.

[@bigtractorpower]

+gone rydin That is neat. You saw allot of machine advancements in those years.

[@gonerydin4225]

That's for sure. They were still making parts for the 2 cylinders when I started there. : )

[@SSBN506]

love this new format. The history adds so much to you amazing footage. Keep up the great work and look forward to more.

[@bigtractorpower]

I appreciate the effort you put into this video. The history as well as explaining what is being done is very interesting. Thanks

[@generationll]

On the 8440,8640 the 16 speed Quad Range transmission went to a single lever.John Deere billed these 2 as Heavy Duty Power,East Duty Comfort

[@matthewearlywine4413]

I'm all about the original IH, but the 40 series is a great line of tractors

[@jankotze1959]

Awesome tractors, thanks very much for this video.

[@rustylanier]

Thank's for the video! It's nice to see some equipment from the time when I was farming. I really can't relate to the new equipment. lol

[@bigtractorpower]

+rustylanier I remember these being new on the lot. It seems just like yesterday.

[@jasonknight4906]

Thank you for watching.

The 8440 was tested in Nebraska @ 179 PTO & the 8640 228 PTO hp .Both were introduced in 1978 with the 2600/2800 plows,Titan Turbo 6620,Turbo 7720,Turbo 8820 & 4420 combines

[@bigtractorpower]

+generationll the sales brochure lists them at 175 and 225. While they were introduced in the fall of 1978 they were model year 1979 machines. This always gets tricky on dates because machines are always introduced at fall farm shows but are listed as New for the following year. For example the 9620R was introduced in August 2014 but the first production models did not hit dealer lots until January 2016. So do you say the generation I 9620R was produced from 2014 to 2016 or do you say 2015 to 2016. The generation II 9620R was introduced in the fall of 2016 but I have not come across one at a dealer yet or in the field. By the spring of 2017 the generation II 9620Rs will be rolling. So is it a 2016 or a 2017 model?

[@gleanerk]

Thanks friend for your time and effort showing us these videos! I remember when these girls were new ! Question? You ever done one like this on 7020 and 7520?

[@bigtractorpower]

The 7020 and the 7520 are in our wish list to film. So far we have not located any to film. I think I have a lead on a pair in Wisconsin that will hopefully be filmed this year.

[@gleanerk]

Sounds good! Thanks again

[@SteveHolsten]

I think Onelonelyfarmer bought 2 of this series before Christmas. He's still waiting on them to be shipped from the UK.

[@bigtractorpower]

The 7020 and 7520 are articulated 4wds from the early 1970s. OLF bought a 7530 fwa tractor from the 2000s and an 8530. At some point I would like to do a video on how many times John Deere has reused and duplicated model numbers. It's an extensive list. The most interesting duplication is from the 1990s when they offered a 9400 4wd tractor and a 9400 combine at the same time.

[@gleanerk]

Confusing but still fun, either way! Thanks

[@interman7715]

Very nice tractors ,could you do some videos on White articulated 4wds please ? Love your channel.

[@bigtractorpower]

We are on the hunt for Field Boss tractors. Hopefully we have some lined up to film in New York in 2017.

[@timwestendorf8303]

i grew up driving an 8640 pulling a 30 ft disc and a 36ft 980 cultivator... dad bought it in 2000 and we put two motors and a tranny and 6000 hours on it before we traded again.... great tractor but making the motor part of the frame was the draw back.

[@framfull]

Classact!

[@markarmstrong3394]

I packed silage with a 8640. I had a BLAST !!

[@bigtractorpower]

Very cool.

[@rlashbrook6865]

Awesome

[@chriscardoza9714]

those where good tractors for that time...

[@markrskinner]

I'd like to see a comparison with these and the earlier 30 series. And while I'm on the subject, another comparison with the later 50 series.

[@bigtractorpower]

I would like to do a run down on the 30, 40 and 50 series showing the difference in the grilles, mufflers, cabs and decals. I need to locate an 8430, 8630 and an 8850 to film.

[@harcid1]

Do you guys ever plan on filming a international 3688?

[@bigtractorpower]

+BILLEDSPIDER if we can locate one we will. We filmed a 5488 and an 856 in 2016. We are always looking for IH tractors.

[@harcid1]

bigtractorpower well we actually have one you can film it if you want just private message me about it

[@johndecker53]

good 👍🚜

[@thegreenerthemeaner]

These tractors were fine if left alone. Too many power happy guys tried turning them up like the 7520/6030. The 619 was fine but the 466 wasn't quite up to it until the 50 series. The transmission in the 8630/40/50 gave enough issue and were it not for the strike in the late 80s, there may have been real problems. The strike gave the engineers time to solve problems. Deere also tried to buy Versatile so they could produce 4x4 tractors and skirt the strike. The Government stopped them by claiming they would monopolize the market. Hardly true.

[@chadjustice8560]

It's ironic that the same thing happened just a few short years ago when Deere had an agreement to buy precision planting but the government wouldn't approve because they already had 70 percent of the planting market so they cost the stockholders of precision planting money because agco was allowed to buy it and didn't pay near as much

[@TwoHappyChildrenFarm]

Great work. FYI you're work is getting poached by another youtube account, Brendon Burney. Not right.

[@bigtractorpower]

+TwoHappyChildrenFarm thank you for the tip. I will look into it.
