IH 1086

Hey guys, I'm looking at a IH 1086 with 3900 hours. It had the rear end split 7 years ago (3200 hrs) because they found metal in the transmission fluid. They rebuilt the clutch and PTO also. There seems to be a lot of these tractors out there, so is that telling me to stay clear of all of them, just this one, what is the low down on a 1086??? Thanks

The one I bought new I still have with close to 10,000 hours. A new clutch and TA at 4500 hours. Lighter duty in its golden years.

The other two I owned were bought used and had about 5000 and 6000 hours each when I traded them for bigger tractors. Put a TA in one of them the other had not been touched that I know of.

I have never had any engine issues. Might be the best ag engine ever built.

The reason there are so many to buy is there were a lot of them sold new. And not many have died. Why were they sold new?

Because they are a good tractor.

I own a 1586 so take that into consideration, this is my opinion. When I was shopping for an 86 series to run on our small-to mid size operation I considered the 1086 and 1486. I found that I kept finding the two lighter tractors with varying amounts of HP when put to test. It seems that some folks were tuning up the turbocharger to get higher HP. If I remember correctly, this was more of a problem with the 1486 as it had the same basic engine as the 1586 so people would tune it up to the 1586 HP. Problem was that the 1586 had a different rear end designed to take the extra HP and the 1486's were failing under the load. I actually ran into people warning me that the 1486 had a weak rear end when the likelihood was that it was just being run over specs. Don't know if this would account for metal shavings in the trans or not, but something to consider when buying one of these tractors. Compare it's rated HP to what it tested at. Other than that, I can tell you that I am pretty dang happy with mine. It's rated 160 HP and dynoed that exact number. Starts and runs out well. Many consider them to be some of the best IH ever made...so shop away.

"The reason there are so many to buy is there were a lot of them sold new. And not many have died. Why were they sold new?

Because they are a good tractor."

That's usually case unless you mention an 8N and then you get the haters claiming they are one of the worst tractors ever built. Pretty hard to argue with sales figures in my opinion.

THE 766,966,1066,1466 ALL HAD THE SAME REAR AXEL ASSEMBLY.

1466 has a bigger axle than other 66's.

Dave and Gary both gave some good answers and opinions.If the hours are correct??,then might-could be a good tractor.86s never sold good in our area because of the 66s reputation.The trans.and rear ends failed bad when they were set to the same HP as the same size Deeres and Cases were running.See if you can talk to the past owner about what the tractor was used for.Can you live with the DOOR???

The castings look the same but I know for a fact that the internals are NOT the same in the models you mention.

Owned two 1066's, one 1486,a 1466, and a 1586, they were all good tractors.

You are right the motor ranks right up there with a 5.9 Cummins. Only thing is if you are over 6 ft the cab is to short. The gear shift lever is on the Left side hard to get into cab. Remember a 50 series JD was made at the same time with a full powershift. For the same money I would look at a 80 series Allis. Or a White. Just a opinion,kinda like belly buttons, everybody has one.

Well, I have a short diary of 1086 ownership here. I'd go for it if the price is right. That's not many hours for that age of tractor. Every tractor has it's bugs and the 1086 certainly isn't bug-free, but it's a pretty good horse all-in-all. Bought my 1086 new in 1978. It saw mostly heavy fieldwork for 15,000 hours. Been through several TA's and the tranny was gone through once. The shifting linkage has been replaced twice. Nothing was broken, I just wanted it to shift like new again. I've replaced one bull pinion and bull gear and I kind of blame the unforgiving 5 shank three point V ripper on that. At 16,700 hours it's still in excellent shape but all it does now is loader duty and pull the planter and sprayer. It's kind of a nice loader tractor in ways, for an older tractor. The forward mounted cab makes for a shorter hood and puts the operator a little closer to the front of the tractor. Gear shift on the left and hydraulics on the right is nice for loader work. I extended the hydraulic livers so they're easier to reach. Downfall is the clunky gear shifting but shifting isn't all that bad once you get the hang of it.

The doors are kind of an afterthought in my opinion, but they seem to last pretty well. I've had to weld two hinges back on inside the doors but the first one was at 14,000 hours and the other one was just this winter, so I'd say they held up pretty well considering. On windy days the wind tries to push the door shut on your butt when you're getting in. One bit of advice concerning the doors is to HANG ON TO THOSE DOORS WHEN YOU OPEN THEM ON WINDY DAYS! Oh ya, I'm 6'2" and the cab doesn't bother me at all. Jim

If you are looking at any AGCO supported tractor check out your nearest dealer. AGCO isn't concerned about how well dealers support older tractors. They want to sell new ones. Our local (12 miles) AGCO dealer mat as well be selling JD if you need parts or service. I've called and written AGCO several times about it and get told "he sells a lot of new equipment". Course he does. When you have to get crops in or out of a field you can't wait on a tractor. So if you can't get parts you have to go new or go with another brand. Next ACGO dealer is too far to reasonably use.

14 is bigger outside axle...cuts down behind the axle cover...from the bearings in....THEY ARE THE SAME...very deceiving.

You haven't lifted many bull gears and axles if you think they are all the same.

IH is owned by new holland(fiat) not agco

Ok,I shouldn't have used the word set when I should have said like for like.4430-40 vs 1066-86 and 4630-40 vs 1466-86 and like tool to like tool.JD-Case-White-AC used that Spur Gear setup very successfully against IH.They were a very good tractor,but they were oversold on what they could do and holdup same as the 560 catastrophe.

They are/were a good tractor. The biggest issue with the power train is not that they are powered up to match JD or anyone else but that they were turned up to match the 1486 and 1586. If left alone they were good for 10 of thousands of hours. The engine was usually good for 10K hours.

3200 hours is nothing if not abused - but then the right fool can break an anvil.

everyone ive seen had ta problems at about 4000 hrs seems like a big problem to me

We never owned a 1086, we owned a couple 1486 and a 1586 though - never had a TA issue with any of them - the TA was usually overhauled with the engine at 8,000-10,000 hours.

Now that I think about it, we owned 11 large frame 86, 66, 56 and 06 tractors - not one of them developed a TA problem (bought 2 used with TA issues though).

We own 2 1086s. One is a 1977 4 post canopy and the other is a 1980 w/ cab (western style interior) w/ 3500 hours. I have to admit, they are good tractors if you don't neglect them. Like others, I hate the door swing on the cab. And every year we have to work on the AC unit.

Our 1980 model pump is turned way up putting out well over 160 hp. Needless to say, you have to be very gentle on the clutch and it drinks twice as much fuel. It has had work on the rearend thanks to my uncle (who bought it new) wanting to pull a disc the same size and as fast as his 1586. The TA has been deleted in both of them. Neither tractor does much hard labor nowadays. Used only for hay crops.

I know that. I was responding about the post that recommended an Allis or White. 10 years ago here they were a good option but sense the dealership changed hands I wouldn't even look at one.

Really? I've heard people say that but every one of them was running a different brand. The guys that will tell you about TA problems in this area are the guy with the newer MF tractors that use to own only AC. He's and his father before him have farmed with MF and AC tractor sense sometime in the 50's that I know of. The Case guy who likes his 70 series and the JD guys. I know 3 or 4 guys with 06-86 series tractors myself included and I know one who had TA trouble and that was because he didn't change hydraulic filter or oil until his hydraulics would get to the point of being real slow. At times he only changed the filter and reused the fluid.
