I"m still looking for a tractor, I have seen a few good ones, but still don"t know what to do. IH seems to be less than half the price, and with lower hours than JD. I suppose someone has asked this question before, but I didn"t find it yet. How much difference would I notice in fuel consumption between the two? I"d be baling with it (5x6 round), running a Haybuster, and pulling loads of around 20,000 pounds of hay/mover. Anyone have a ballpark estimated gallons per hour or something like that? My 1855 Oliver handled all of these well, and was very economical doing it. Also I"ve seen a few of these around, some being overhauled around 5000 hours. Is one model more reliable than the other? I know it depends on use, but how long do some of the components usually last if taken care of? Most of the ones for sale around here have new clutches, some new ta. Seem to be about 4-5000 hours on either for about $10,000 to $14,000. Thanks.

al: Having farmed with a 1066, 560D and 656D 25+ years ago, I'd never look at a 100hp+ tractor for doing hay in round bales. Unless you have heavy tillage or forage harvester work, those big tractors will just add to your expences. I round baled hay, 5x6 bales and can tell you the 1066 remained parked or out on custom work during hay making. We did all our baling with 560D cranking out 90 hp. I found it was actually faster than the 1066 and burned about half the fuel baling hay. I once had a couple of jobs going where all tractors were busy. I rented a 766 from the IH dealer to pull a liquid tanker 3,000 IMP gallons, on hard ground, relatively level so it handled the job just as well as the 1066.

Having said all of this, I also owned a John Deere 540A forestry skidder, 100hp, 8 speed power shift and articulated. On tillage work, it would give the 1066 a hard run even though the 1066 was cranking 150 hp. I vowed in 1978, if I ever bought another tractor over 100 hp it would be articulated. Two wheels will not put 100+hp on the ground, if you dual it, it will beat the crap out of the front end, If you add front drive, you have one heck of a cumbersome expencive tractor to operate.

This spring I had the oportunity to operate both NH and Deere 350 hp articulateds. They both have as short turning radius on a headland as a 2 wheel drive 1066, and they will do it at 4 mph without jumping on a brake pedal. To me 100hp+ two wheel drive tractors of the 60s, 70s and 80s are little more than scrap metal, and if you pay more than scrap metal price for them your out to lunch. Doesn't matter whether they are IH, JD, Oliver, Case, etc.

go with the 1086, youll be happier with the turbo charged engine, there more efficent, there putting turbos on what seems like any engine that runs on diesel, i saw one the size of an oreo cookie on a lawnmower the other day. the n/a motor is good but a charged motor beats it hands down anyday... there also easier to turn up :)

Dad had a 986 with 130 HP on the dyno from the factory.

I had a 1086 with 150 HP from the factory.

Both bought in 1979.

On the same 5 bottom plow the 986 would burn 5 to 6 gallon per and the 1086 would burn 4 1/2 to 5 1/2 gal an hour.

In my thoughts the turbo will save on fuel.

Would it make much difference if it wasn"t under constant load? With my old tractor, the baler seldom worked it, couldn"t hardly tell it was there. Also with the bale mover, aside from starting it to roll, it"s not hard to keep it going, not working the motor much. Different than farming type applications under constant load. Less load/less need to use bigger quantities of air? I"d just like something reliable and fuel efficient, I"m used to taking not much more than 2 gallons per hour under heavy load, barely over one under light (Oliver, 99 pto hp). I don"t have many choices here, there is a decent 1086 close to here for cheap, sounds and looks goo but unknown hours and use, I"d like to look at a 986 just to see one. Another question, I don"t know what year they started with closed center hydraulics (I know I saw it here but I don"t remember without looking). I know they are a lot of $$ to fix, but how reliable are they? There is an "81? 1086 where the 986 is, if it"s still there.

The 81 model is when they went to the different hydraulics.

I have one of both Hydraulics an 81 and the 79 I mentioned earlier and they are both OK.

This spring pulling a planter the 1086 used about 2 1/2 to 3 gallon hour and I'm sure it is less on the round baler. Never really checked it on the baler.

That"s more reasonable! The one where the 986 is located is an "82 the dealer says, but duals @ 50-60%, weights on both sides of the duals, and weights on the front, so I"m guessing it was a puller.... 5600 hours, new clutch, don"t know about OH. Pricey, but if it looks good possibly? The 986 is $1000 cheaper, also new clutch, the salesman didn"t know the hours because they have it rented and didn"t write it down..., didn"t ask the year either, I"m guessing lower hours perhaps, they rate it a 7 out of 10 in condition, the 1086 is an 8, and they don"t have any pictures on their website. Thanks for the replies all.

Don't want to tell the dealer he is wrong but they never made a 82 model.

I didn"t think so, but he said it was from the last year, it says "82 in the ad also. Maybe get him to knock of a few $ (older than they think). Oh well knew what he meant.

In my opinion, they are going to be about the same on fuel, with the 1086 using slightly more. The 986 has 436 Naturally aspirated motor, and the 1086 has a 414 turbocharged motor. Also If interested, I have a 1486 for sale,
Factory no TA, 4 post canopy, newer paint, tight motor. Drop me an email if interested, and I will have pictures and more info!

Thanks for the info. I"d mainly like something with a cab, Oliver sort of had one, but had no working heat or air, so I don"t care about that as much. A cab makes a nice windbreak when it"s 10 below with 30 miles an hour wind and snow.... It"s also nice to keep the dust from directly blowing in a person"s face while baling (for 6+ weeks). Also probably closer to NE. I"ve never looked at a 986 yet, closest one I see right now is four hours away, but I"m going to look at it if it"s still there. Why didn"t they put turbos on some of their smaller tractors (JD either)? I don"t know how much they help efficiency wise, but I sure liked both the power and economy on my 1855 turbo.
