Oliver Hydra-Lectric... What is it?

- By 1950, Oliver had a hydraulic system that was not only live, but totally electric over hydraulic. It was ahead of its time, and perhaps because of that, the electric switches and components had trouble with dirt and moisture. Most farmers cut the external wires off both the hydraulic unit and cylinders and used them as a simple up and down lift. When they were fully functional, the operator could adjust the position of the depth stop on the cylinder from the tractor, and then just move the lever up or down where it would lock in until the cylinder reached the end of its travel.
Thank you very much! Just bought my grandfather's 1951 Oliver 77 and back home.
Very nice!
Thanks for sharing. When we bought out 1962 770 had it. It was very handy.
We just bought a 770 diesel with front loader. I saw the wire were cut just front of the levers. This saves me extra work now. I don't implement. Will just work a Gannon or rippers. The reservoir doesn't stay full. I thought maybe the front loader rams were dry and thats why I kept pumping in fluid. We bought all the manuals from Jensales. Best I guess to take off the reservoir and rebuild it. Need that break ram to work.
We had a 77 Oliver with that pretty cool
thanks for making this video its very informative.. i wondered how it all worked..
Glad it was helpful!
Cool beans, I didn't know about these on the Olivers. I clicked on the link from Ross' video on the 1650, thanks Chris, I hope you have a good night!
Thanks Dan! The patent for the hydra electric is large because they had to invent so many things to make it work.
I would agree that it was ahead of it's time. I just got a Super 77 diesel with the Hydra electric system that is not all there and I have to decide whether or not to repair it. In the 1950s Chrysler developed an electronic fuel injection system for the big Chryslers. Although the engines ran well, the components could not handle the weather. The diodes would fail. Chrysler recalled them and all and converted them back to carburetors. I'm not sure which engine was used for this but I believe it was the 392 Hemi.
I hadn't heard that before. Cool history!
Dad got it on his brand new 88 in March of '49. It worked slick and yes it had its issues. My brother still has that tractor and it runs. He has a sentimental attachment to it as he can along in the same month.
I had no idea about the stop collar. Thanks for sharing! There’s a Super 66 behind my house that has a cultivator under it with all the wires running to the hydraulic cylinders. I’ve got to check that out.
Super cool! Super cool! I knew how they worked in theory, but have never actually seen one work in action! That is still an awesome feature today! It really was so far ahead of it's time, that even today, it would still be considered an advanced system! Thanks for the video and demonstration!
I wondered why the hydraulic levers had those buttons on it. Thanks for the explanation.
Thanks for the video! I’ve never actually never knew how they worked correctly.
Have a 65 1650 the buttons are still there on it and some of the wiring, would be neat to get it working again. Will be rewiring the the whole tractor in the near future, the 55 year old wiring is showing it's age
My 1655 has those buttons. I also have a 77 that had the electric, but like you said, the wires were cut and the switches are stuck. My super 77 , I wondered why the hydraulic levers moved that way. Thanks for sharing
thanks i still have the button on the 1550 but the wires are gone same way with a cylinder hopefully some day it. will be restored. i always wondered how it worked and now i do
So far ahead of their time. Unfortunately didn’t have the electrical sealed good enough
Fun fact: if you have closed captioning on, when you start the super 88, the caption says “music”
Cool, They know music when they hear it!
We have a 1555 diesel with that system, it's original to that tractor.
I've got a couple of them old cylinders at then home farm
When did Oliver come out with the Hydra hitch three point? I assume it was their first three pointer. I've seen older tractors with it but no one seems to know if they were factory mounted or retro fitted kits put on later. Thanks.
I don't know exactly when , somewhere around 1953. It was an after thought on the part of Oliver, trying to play catch up with the other brands. It was a bolt on unit that could be ordered from the factory or added to an existing tractor. There were quite a few variations on it as well, due to design improvements that always go with a product that is rushed to market. They did much better with the Super 55 and its integral 3 point with draft control.
@@ThatOliverGuyChris Yes the did.
@@ThatOliverGuyChris Yes they did on the Super 55 Nice tractors!
Chris:. I am restoring a Super 77 gas with a series 3 Hydralectric system (just like the super 88 in this video). If I do not intend to use the Hydralectric system and instead just plan on using regular cylinders, do I still need to put on the Hydralectric wiring harness when I rewire the tractor?
You can use regular hydraulic cylinders with it and leave the wiring harnesses off. It's common to find where some snipped the harness off and left the base in to keep dirt out. Korves Oliver has reproduction harnesses if you want to put a set on for looks, and you'd still be able to use a regular cylinder.
If you can fix a diesel engine you can fix the systems too but once someone ripped it out it was gone.
So, on the series one system, did the switch operate a solenoid valve?
RustyCarnahan That's correct. On series 1 and 2 there is a solenoid on the inside that actuates the valve. Series 1 did have a small peg on the side that you can put a small wrench on to manually actuate the valve. Series 2 had levers built into those same spots that were much easier to use, but still had the internal solenoids. Series 3 had to be run exclusively with the levers.
Chris Losey, thanks. That clears up just about everything I've ever wondered about Oliver's Hydra-Lectric setup.
Why doesnt my 1855 return to neutral when done back or forward on the handle
David Hunt That's a detent type valve that just needs an adjustment. Sounds like something for another video.
Chris Losey ok cool so it can be adjusted !
Yep. You pop the cap off the back of the valve and stick an Allen wrench in there and turn it to adjust how easy it kicks out. I don't remember the wrench size off the top of my head, maybe 1/8".
I will check it out...thanks
I have a oliver 77 i bought i need your help to help me identifiy which hydraulics mine had
There is a series 1 hydraulucs
There is a series 2 hydraulics
There is a series 3 hydraulics
There is a power tool hydraulics
I am not sure which hydraulic lift mine has can you make me a video going over abd talking all the hydraulic opitons for a 77 oliver
Also you hit the lever down by hydraulics to start do all oliver 77 start this way mine dies not have that lever ny hydraulics ???
The series 1 hydraulics don't have a filter and no mechanical levers, it was all operated by electric switches.
Series 2 had the electric controls, but also had manual levers on the side of the reservoir. The electric may have been removed over the years
Series 3 had the levers out the top and no electric switches.
The power tool hydraulics was entirely mechanical, and you rotated the levers instead of moving them up and down.
@ThatOliverGuyChris on the second oliver in this video you pull a rod/lever down low by hydraulics to start this tractor do all oliver 77 have this mine does not ??
@ThatOliverGuyChris and were there any oliver 77 that came from factory without pto ??
Mine does not have pto it I think it is factory no pto is this rare ??
If your tractor had series 1 hydraulics and you had dual remotes would that mean 2 electric levers by steering instead of 1 yours in video has 1 not 2 ??
@@TeresaJohnson-ew4us that starter lever was only on diesel models. Gas engines had a push button on the dash. Any of the hydraulic units could be ordered as a single remote with only one lever and/or switch. Pto was an option the 77 could be ordered without. It's pretty rare to find one that way from the factory, but it did happen. A lot of them don't have it now because guys take it off to lower the weight for tractor pulling
What is a hydra lectra worth. We had Oliver’s we I was a kid
A complete working unit ought to be worth $500, more if it has been gone through.
Run the tractor and show us. Talkin about it not helpful
