Out of the Hydro models produced (HYDRO 70, 84, 85, 86, 100, 186, 268) were any of them good tractors? I work with a retired tractor mechanic and he says that they were a flop. Is there any truth to this?

I think it would be an interesting tractor to find and clean up to presentable standards. Were there many of them? Was it the loss of useable horsepower from the hydrostatic drive that gave them a bad rep or did they actually have issues? I do know that you give up 10-20+ drawbar HP over rated PTO HP.

Help me out on this one...

They are one of the most handy tractors made. That being said, know going in that if that Hydro acts up and requires repairs, you could potentially spend as much on repairs to the hydrostatic as the whole tractor is worth. I wouldnt be afraid to buy one that had obviously had a good life, but wouldnt get near a Hydro tractor that showed any signs of a hard life or lack of maintenance.

i have a 656 hydro diesel. i am third generation owner of it. I still farm with it. Do almost everything with it other than my tillage. Plus clean out barn with it all winter long and it gets pertty cold up here in MN. I can rember my father planting about 200 acers of corn with it, spraying, bailing, choping, and filling silo, every year for proubly 10 years. It is proubly still my favorite tractor next to the super c.

My Dad bought a 1026 IH hydro new in 1971. An unauthorised user put it off a 100 foot embankment one winter night. It was a terrific tractor,same engine as 1256 IH. We used it for everything from chisel plowing to moving round bales. Occasionally one will show up on an auction,if in good shape they bring well above new list price in 1970-71. The newer hydros like the 186 and 3488 were quieter. If anyone had one for sale I certainly would be interested. Joe

the hydro was a good tractor if it was used for its intended purpose. for loader work, spraying, planting, baleing ect it was good. it was not a primary tillage tractor. you wouldnt want to chisel plow or v-rip with it. it was hard on fuel and just plain wasnt designed for heavy tillage operations. for infinately variable speeds, it was a dandy.

Glenster, I am looking for a 656 hydro, but am a little bit confused. I was with the understanding it has the same engine as the 560 had and everybody says the 560 was a sipper on diesel fuel!Doesn`t make sense. Could it be the Hydro took alot of hp to run it? Thanks

The Hydro trans. is not as efficient as a gear drive, same power in=less power out.

No,

The hydro doesn't take any more "horsepower" to run it. It's just that people don't use 'em to their max effeciency due to their built-in infinite variable speed design.

If you were to run that ratio control at the blue line, both servos are at a ratio of 1:1 and equal to a gear drive.

Only trouble is, the only other option you have for increasing or decreasing speed is that throttle. That's why folks find it easier to just adjust speed with the transmission control.

Move the lever back from the blue and you're losing efficency because of the increased power ratio. Move the lever ahead of the blue and you're going into an "overdriven" ratio, but you also lose torque.

I have 50 acres recently cleared and plan to have a few horses and try to run a meat goat farm (100-200 goats). I have a Farmall 504 (which I have asked many questions about here) and later I would like to maybe get a larger "Red Iron". I have a loader for the 504, not installed yet, but why not have a loader on all tractors. I would mainly ues it for loader work, brush hogging, round baling (father has 140 acres and cattle), and at most pulling a Massey Ferguson 10 foot tandam or a 5 point chisel plow on the rare occasion. Also, a 4 yard Reynolds scraper that I know my 504, JD 3020, and Ford 6600 can pull.

I was looking at the Hydro 86, 100, or 186. I did not know that they commanded a premium price. I have used many hydrostatic industrial machines and they are fine in applications where controlled speed is crucial.

Thank you and more information is welcome.

Great tractor, the Hydro 70. We use it for odd jobs, no pulling hard, just use the EZ ON loader or rear blade for minor stuff. Great for lifting things, but I do not full time farm, so it gets little use compared to some places.
We do really love ours for chores .....
