IH 966 vs IH 986

[@jamesranger6283]

Used a 966 as a teen working for the neighbour up the road.Great tractor. Did have the larger rear tires and no duals. Seemed to have endless power and trouble free.

[@raymeschuerer4223]

If my history is correct. The 966 and 1066 both have 414 motors the 1066 being turbocharged. The 986 has a 436 motor ( no turbo) like the 1486 ( has turbo) now the 986 motor does have a different head than the 1486 motor

[@ih1206]

Dad always referred to 86 series as guy shakers for the seats sitting so far forward. I never ran one, spent plenty on time on the 06s, 66s, and 88s. Good tractors.

[@1717BY]

I really like these videos! For me as a german it's very interesting to learn more about the US built IH-tractors. 624, 733 and 1246 are the tractors you see around where i live, of course all german models.

[@Sparkchaser1]

Spent a lot of time on a 1066 and a 986 as a kid . 1066 just pulled the hell out of things. But the 986 had a cab and a/c so it was appreciated, although less power

[@klwarhouse]

As a kid i had a choice of a 766 with cab.... Or a open 1066..... Even in NY snow, i always choose the open 1066.

[@farmalllover8217]

Nice video. Eventually you should get a 1066. I hope to see the 560 doing some work this year.

[@brucelavertu5318]

We had a few, 656,706,1066,1486. Oh, and the m. All served us well. Not perfect, by any means, but reliable. Really good engine on all of them.

[@wordlog860]

Nice, we're still rocking a 1066. We got rid of the cab too. It's an oldy but a good one. We use it for a lot of stuff =p We used to take on and off the duals back in the day.

[@MrMan5014]

To this day they are still a great chore tractor and very rebuildable!..and reliable!..if you have a big operation or even a small one, you are silly not to have one or three of these old IH’s in your fleet because when none of the other new tractors will start, these ones will!..

[@BrianSmith-lo3mj]

We have a 966 Hydro and it's one of the best tractors we've ever owned. My future plans is to restore a 1466 Turbo with the 436 engine.

[@PAFarms]

Nice. Yea they definitely are nice tractors

[@northtexasranchette4667]

Thanks for sharing your knowledge of both series. I don’t mind ether one. Here in the summer I prefer a tractor with ac in the summer. Both make my 2444 look small.

[@crslyrn]

I have to admit, I like the styling of the IH 966. It looks like they've taken fairly decent care of it. The guy doing the work has some nice older equipment that he's using to get your waterway fixed up. Stay safe.

[@turbo5488]

The international tractor's that I like is the international 806 and the 856 next up 1066 the 1466 the 1586 the 5088 the 5288 and the 5488 but international tractor's are still number one in my book and I'm very proud of the international tractor's that's what grandfather had was all international tractors so me and my grandfather loves international tractors hands down they are the very best tractor and so isn't there garden tractor's they the very best as well

[@lowgearfarms1195]

The 966 was originally built with a 414 engine.

[@tannertuner]

Correct. The 966 had the same engine that was in the 1066/1086 but without turbo. The 986 had the 436 that was in the 1466/86 and 1566/86 except no turbo

[@johnglover5071]

Thanks for the video. I have put a lot of hours on 66 and 86 series.1066,1566,1086,1486. the 66 rides better.the cabs are nicer on 86.my favorite to drive was a 766 that had the fuel turned up on it.pulled 4 bottom MF flip plow and with duals pulled a 16' Krause harrow.

[@FarmallFanatic]

I'll never understand the guy that says A766 can outpull A966. Sure if you turn the pump up but it wasn't designed right out of the factory to pull more.

[@2cylinderjohndeere720]

The cabs are nicer on an 86 series and newer. But I always hated how the levers are on an 86 series getting in and out. On a 66 series that is easier getting on and off. I always liked the 66 series a lot better as long as they are open station.

[@tannertuner]

We had both a 1566 open station and a 1586 with cab. I was trying to harrow a field once that hadn’t been plowed in a year or two and was grown over with the 1566. The bugs just about knocked me off the tractor. I was across the county and couldn’t just go swap tractors. Never did finish the job. Decided not to rent the place.

[@robertunderwood6984]

@Brad Jenkins.My bad,I use to help a that I knew sometimes that had 1066 tractors.He said the told that those1066's had DT466 engines.Thanks for the information.

[@tannertuner]

According to Tractordata, the 966 and 1066 (and 1086) all used the D414, but the 1066 and 1086 were turbocharged. The 986 had the larger D436 - same as 1466/86 and 1566/86 but non-turbocharged

[@marshallk4355]

I agree completely with staying as far away from 3pt equipment as you can!! We farm in central MN where there’s a gentle roll to the land and even here you can’t give the stuff away that’s 3pt mount our trouble is you get stuck in the wet spots with it to easily cause it drags you down so bad Great video!!

we have a 1486 and fuelling for me is a pain wish we had a 986 but i am of the mindset now what ever gets the job done

[@robertunderwood6984]

@69druth.The1066 has a DT466 turbo charged engine.Spent a lot of time on a 1066.A good powerful tractor.I liked very it much.Too bad that International tractors ended the way they did.I also had some time on a John Deere 5010.What I liked about that tractor was so that heavy that it didn't bounce while plowing or discking the fields.Because the fuel was in front of the radiator,the fan blew up dust and trash up in my face.Had the wear goggles.That old 5010 sure could pull.

We had two 574's. One with front end loader. I think rated at .... 65hp ? Loved them both . Pulled pretty good too. We had forks front and back on the one . Pick one 1000 lb round bale front and back . The 3 pt could handle more so that's where the greener bale went ... Lol

[@AaricHale]

You really know your tractors ! It looks like there doing a good job so far on the waterway .

[@uthermaceanruig5098]

As soon as you attempt a starter change on a 86 series, you’ll suddenly develop an appreciation for the 66 series. Lol

[@69druth]

The 9 has the 436 and the 10 has the 414 turbo. I am pretty sure that's correct. I know our 9 has the 436. Back in that time they were king and if they had a power shift at the time they still would be. I remember a old fellow saying that if somebody went broke and had green tractors and blue silos that's why. Lol

[@PAFarms]

I posted the original version saying that and I had about 6 people correct me and say the 966 had the 414. I never noticed that. I did the valves on one once that was the 436. So it had me wondering if the later models had the 436? Either way I figured I better re upload the video so I don’t give out bad info. This one is stamped DT414 so I figured they used a 10 block, but it doesn’t have a turbo

[@oldfarmer4700]

Where I grew up everyone that had green tractors and blue silos also drove fords and were members of the NFO. We always had red and orange and drove chevy's and weren't a member of the NFO. We just couldn't see dumping thousands of gallons of milk on the ground. Oh the olden days.

[@bradjenkins932]

966 has a 414ci. A 986 has a 436ci.

[@69druth]

@@PAFarms l didn't know that they had the 414. We had a dealer trying to sell 1086s with 986 components. He put 1086 decals on 986s. IH pulled the plug on him.

[@redpower1086]

We have two 966’s three 1066’s a 1086 and two 1486’s. The 9’s both have d414s. The 1066 all have dt414’s just like the 1086. The 1486’s have dt436’s. The axles on a 966 are the same size as a 1066 at 3 1/4 inches I believe a 986 is the same. The 1086 and 1486 are 3 1/2.

[@scotcoon1186]

1086, 1466 and 86 have 3-3/8 axles, they use the same wheel center as the 3-1/4 axle with different wedges.

[@SilverGleaner]

IH always ran kinda small axles. I worked at the local AC dealership and one of my best friends worked at the local IH dealership and he said they kept in stock an axle for 1066's. A comparable AC would be a 7030 and that axle was 3-5/8", replaced by the 7040 a year later with 3-3/4" axles and later the 7045 that had an optional long axle with 4" diameter like all 7080's had. Later I worked parts for a CaseIH shop when the 66/86 series were still a main horse for smaller farmers. I saw a lot of rear end work on 10's and up. Great engines though. I've heard farmers who have owned both AC and IH say if AC would have used an IH engine it would have been the perfect tractor.

I have the 1/16 966 Prestige with cab and duals and the 1/16 986 tri stripe with cab and loader in my IH Stash..

[@danielhenebry8506]

Moving the cab forward is what made the 86 series ride so bad on rough ground. The cab according to my neighbor was designed by farmers wifes that hated their husbands. The 88 series fixed alot of the issues and finally a hydraulic clutch, a transmission you could shift after letting the clutch out and disengaging again. Imothe magnums fixed all of the problems except the cab filter over the back window.

[@scotcoon1186]

As long as the door and window seals are good, the filter is self cleaning, every time the door closes.

[@neilkratzer3182]

Not sure about the rear end. But the motors were smaller. The earlier ones I think up to 78 had an international 360 engine. Great winter starter. The 78 model and later had the 358 German engine. Harder to start in winter but a quicker response on engine
