Rice combines were introduced in 1979 (1460 and 1480 but not 1440). My 1979 1460 rice combine has the old style fuel pump. Thx-Ace

Wow ! This reads like the history of the IH Axial flow. You have surely put a tremendous amount of work into researching this information. Thanks for doing such a wonderful job.

You could get long sieves in the last couple years of 1660-80

Please explain to me what a rice combine entails?

lightninboy · October 9, 2018

And the pull-types?

ST-470 · October 9, 2018

Great list!

I still can't understand why they put the 436 engine @ 190hp in the 1480, then took them until 1981 to finally go to the 466. They were sooooo underpowered.

Rice combines came with the rice rotor (later replaced by the specialty rotor), no grain tank extension, raised leveling auger, larger rice and cane tires, special steering axle or mud hog, long feeder house, serrated feeder chain, swing up ladder, long unloading auger. I would have to look it up for more specifics.

The rice combines are given a special section in the brochures. There was also a 1420 rice combine but they are rare. I have only seen one but 715 rice combines were common, I have a dead one.

Externally a 1460 looks like a 1440 due to the small grain tank (there is a short extension at the front of the tank). However it has large front and rear tires, a raised leveling auger and a long unloading tube.

WOW! I feel smarter just having read SuperIH's post. We should make this a sticky post so it stays on the first page for quick reference without having to do a search for it. Just typing that all out was a big chore I bet.

ST-470 - Back in those days, late '70's, '80 & '81 with ag, namely Farmall, East Moline, and trucks ALL going like gangbusters Melrose Park was exceeding their capacity. Trucks used lots of 466's, and 3588's too. Melrose was happy to have Farmall and E. Moline buy some Nuess engines and relieve the demand from them. The few months in '79 I dealt with Melrose nobody took the time to explain to me WHY I could get some displacements easier than others. Product Forcasting that worked right next to us sent a schedule to Melrose every month of what we were going to build and at what rate, so many per day, I monitored daily shipments and the stock expediter just called when he was getting low on an engine, I'd call Melrose and let them know to ship heavy on that engine or I'd call the Big boss the next day. Had a discussion with Melrose's Traffic Manager one day about using other brand engines in a Farmall. He suggested a Detroit 2-stroke. "Ohhh, Heck NO. Cummins if not a CAT." Couple years later when I was driving, picking up a load of engines I stopped in and said Hi to him.

Neat list. Hoober's used to have a similar timeline, but it doesn't seem to be on their redesigned webpage anymore. I agree with Doc Evil, BJ(FarmallFan) should pin this post somewhere as there are a lot of posts on here inquiring about all the changes from year to year, model series to model series. This would answer many of them. I can think of some additions that I will probably add along the way, but it is a great list overall.

IH Forever · October 9, 2018

This is very interesting. But I’m curious do the “Heritage” machines end in 2008? I thought that later models like the 5088 and 6088 where also “Heritage” machines?

A 466 will wake up a 1460!

cougar766 · October 9, 2018

we bought a 1640 summer of 1991 as a 1991 serial # and was told she was the first year of the junk 5.9L cummins and that if we had found a carry over 1990 it would've had a DT436,,,, but I never knew for sure..

this is an amazing post of the history

"SUPERIH" Excellent work!!!

What Other folks have said about Pinning to the front is a great Idea. We have a 1660 with a 466, My serial number is at the end of production for 466's, wondered where it fell in line at.

Thanks for your hard work, Jim Droscha ( Our Lake house is on Upper Evans at the end of 18 mile road off of 90th, How close is your farm from the Martini Lake Chain )

Wow, grew up at 18 mile and the county line, so 9 miles directly East of your lake house, get ahold of me next time your up, would love to meet you and show you around.

This is simply combining a couple of documents and the notes I've taken into one comprehensive document, hopefully everything is accurate.

I finally pulled the trigger on a beautiful 2005, 2388 myself, this information helped me make the decision!

superih · October 10, 2018

I believe the 5088 and up are now referred to as the "Midrange" combines, but certainly are descendants of the "Heritage" machines. One big change is the heads no longer interchange between the two generations.

Pictures of the combine you will love the 2388.

Just remembered to post pics of my new to me machine, was a soybean eating monster!

IHhogfarmer · November 21, 2018

Bueatiful combine they are fun to run aren’t they?

ChrisNY · November 21, 2018

Nice 2388! BJ can you pin this to the top?

1986---"Separating area increased by 24% on 1620, 32% on 1640 and 1660, 41% on 1680"

please explain? I'm pretty sure the long shoe machines came out in 1990 when the CDC engine came out, AND the logo change from big black model numbers to small numbers. I think all 3 occured at once.

I know my 1480 seive, shoe parts will fit in an early short shoe 1680.

also 1985. Cabs tops were painted red, and they were Case IH machines.

Might be talking about the increased size of concaves.

SDman · November 21, 2018

The separating area increase in the 1600 series was due to all the extra holes in the back half of the cage that the 1400s didn’t have.

Also, the first CDC/Cummins engined 1680s did NOT have the long sieve. I’ve got a couple short sieve, Cummins-engined 1680s around here.
