966 hydro


Recommended Posts

so what is the scoop on those, are they the predecessor of the hydro 100? i was thinking the hydro 100 was a 1066 w/hydro or ? 

i remember a 656 hydro so what about all the other hydros?  i was thinking the 966 was non turbo too like the 886/986? or they diff engines?  

hydro same engine as a gear drive unit? wondering if they detuned them due to hydro trannie?

The Hydro 966 had the D414 engine. The Hydro 1066 had the D414 with Turbo. Both models were replaced with the Hydro 100 that had a D436 engine. The Hydro 100 was replaced with the Hydro 186 which shared the D436 engine with the gear drive 986.

oh interesting were they all the same hydro units in the 966/1066/hydro 100 and hydro 186? wasnt there a 1026 hydro, i think my 1026 ertl is a hydro but i still have to push it LOL - where did that 1026 fit in there? 

 

I rekon the hydro 186 was most desired due to cab/comforts

There were some minor changes to the transmission between 966/1066 hydro and the hydro 100 but basically the same. The 3488 in the 88 series was the last hydro.

comparison between the gear drive and hydro was not favorable to pulling power on a hydro so IH changed the numbers. The 666 hydro became the hydro 70 and 966/1066 hydro became hydro 100.

The hydro is the greatest tractor ever for pto work or just riding around.

Not for me...............Most desired one for me would be a 3488

whoa i didnt even know they made an 88 series hydro - i would think they would make a great loader, mowing, tractor, maybe not HEAVY CRP type mowing due to the heat/loading of the tractor but outside that maybe great for mowing - raking - baling?

Yes they are. Close to bought one for a mixer tractor 17 years ago ..... 

Dad and grandpa bought a new 656 diesel hydro back in the day, it was traded in 81 on a chummers 6080. We bought a 1066 H around 14 years ago and had two 186 hydro on the farm at the same time 8 or so years ago. I am waiting for pictures of a family 186 from my uncle's estate to make a decision on that if I can swing it somehow.

I like the hydro for many things. Brush hog is one of the nicest things that our 1066 is used for now

1026 came before 966/1066. The 1026 was made along side the 56 series.

seems i recall some place in NE or SD ( guys on here talking about that place ) that rebuilds the hydros completely - thinking to the tune of around 12K?  or something around there so if a guy finds one figure on adding that to the mix if its not working

      Most of You Folks Know we have Several Hydro's on our Farm.  The Basic Design after the 1026 Were all 966 Hydro's with different Hoods & Cab's.

We Had a Chance to spend some time with the Owners from Herrs Machine Hydrostatics Inc. in Washington KS, at a resent Tractor Show.

These Fella's Shared a Lot of information with Us that Tractor Show Afternoon, We Really Enjoyed The Time they spent with Us.

The Term Large Frame Tractors was very Helpful in describing the Internal Difference's of the Different Hydro Units, 

An 826 Hydro Internals are different from the 966 hydro Internals, even though the Bell Housing will bolt to the Different engines.

We Purchased a Pressure Gauge Kit,  used for checking the "Hydro Internal Pressures" .

This Kit Helped determine we had a Bad "Foot & Inch" Valve problem, We thought our Hydro Pump had failed,... Repaired the Valve, Back in business.

Our First Hydro was a 1970 544 Gas Utility, 2000 Loader,     Second, 1970 1026, a 706 Gas was the trade in tractor.

I Purchased a 1970 Gold Demo Gas 656 Hydro at our Neighbors Farm Sale last fall,  Hasn't run in 10 years, Gave $1700. we will restore it.

3488's had a D466 engine. Wonder why they didn't just use a turbo engine? I can't think of anything else that uses that engine.  Early 1640 combines maybe?

You are correct that the early 1640 used the D466. I didn't realize that the 1640 ever used the non-turbo version of the 466. https://www.hoober.com/Images/CurrentAds/AxialFlowTimeline.pdf

I always think of the 1026 as a hydro version of the 1256 performance wise, even though they weren't made at the same time since the 1026 came about with the 1456 timeframe.

Engine wise it is. But a 1026 has the lighter 3-point of an 856. I’m not sure how many other components are even comparable to see what it shares with an 8 vs 12.

Used to some 966 and 1066 hydros in the area. Dad leased a 966 hydro with a row crop cultivator from local IHC dealer. Buddies have a 1066 factory all wheel drive hydro. A 966 combo like that would be rare.
