I always joked about an electric tractor needing a long extension cord. now John Deere has a 1000 m cord, 400 hp electric and it drives itself.

What's next? A neuclear battery that last forever?

2 things:it would probably have to be 3 phase to be a practical power source and for that much horsepower/electric motor size .and second is it just me or did community tractor as referenced in the article suggest lets just say progressive philosophies?
 
A half mile long extension cord that can power a 400 HP load.

At 600 volt the cord would weigh more than the tractor so what voltage are they expecting the farmer to play with in a muddy field.
 
The big draglines used for mining are cord powered.

Also not uncommon to use drag hose when pumping the manure of of livestock facilities and applying it to fields.

Wouldnt work very well for cultivating though.

Most people are surprised when told the size and cost of enough lithium batteries to replace 10 gallons of diesel fuel .that would be 150Kw of batteries and would require at least 21 square ft of storage area .
 
This was discussed a couple years ago here.

Best I remember it is 600v 3 phase.

Requires a power station in the center of the field at every location within range of the extension cord.

It is probably an isolation transformer for safety reasons.

Would be very costly, plus the tractor would need to be transported every time it needs to move to another location.

Determined, if the cord outweighed the tractor wouldn't the rear wheels in the pic below be off the ground? I am no electrical expert, but so far in my experience the higher the voltage the smaller the wire.
 
May be wrong, I thought I read 600v DC which would be safer, no ground to worry about.
Only have to worry about touching both wires at the same time.

Read another article 2.5kv ac. Tractor uses 700vdc. Not sure where the AC is converted to 700vdv.
I think it would be extremely dangerous if the extension cord carried 2.5kvac.

I read about the inventor. He's from California and been working on his cordless tractors for 30 or 40 years.

I also read about 20 or more companies are working on cordless or hybrid tractors.

Times are changing.

Big Brutus here was electric. I had some pictures of the cord that ran it but lost them on a computer a while ago. They used it to line the sidewalks. If I remember correctly they ran the cord directly to an electric power plant.

Looks like there is a sensor receiver (silver) at the end of the telescoping arm telling the tractor how far out and away from the tractor the extension cord is. I bet the tractor is programmed to stop if the cord is not extended far enough away from the implement being pulled. The extension or retraction of telescoping arm would have to operate from the tractors computer also.
 
I would be slow to sneer at this evolution. And I'll cover my #$% by saying NOT EVERY CURRENT PRACTICE WILL USE THIS!

1. You see many nurse operations bringing out supplies to the field. Why not batteries?

2. If you have watched all the equipment and help that satisfactorily support spreading liquid manure on large fields with the feeder hose running through culverts under roads and are drug back and forth behind the applicator across the field, why not power cords?

3. Of course the anti-greenies will point out that the electrice source will STILL offer pollution...how about the no-brainer that a large electricity producer or group of GREEN solar and windturbines would be as or more efficient than many diesel or gas engines doing the job.

It doesn't seem so impossible to me when I think back to the family tramping (threshing) the crop after the whole big family scythed and bundled the crop....a mechanical reaper and it ties it into bundles....HAH...when pigs fly!

I own a little stock in the parent company IDEX. I think this has potential, just needs to be proven and refined over time. IDEX has several different ventures.
 
We can control an autonomous vehicle on Mars a 128 million miles away without a cord, why would any manufacturer want to do it here....
 
Google Amax draglines. There were many around Terre Haute.. Huge beast.
Totally electric and massive power lines cords.

Exactly my point, the cable shown in the picture is no where near big enough to deliver the amps required for 400 HP at 600 volts.
So either they are over rating what it can really do or not showing what the actual cable will look like.
 
I think we need to look at what might happen in the future, zero carbon in 2050.

Many companies are looking at Tesla and Prius.
I think hybrids and cordless tractors will be in the future. Especially in California.

Who knows what is going to happen? Tractor manufacturers, over 20, are hedging their bets on electric tractor.

Determined, I will go with the JD information myself. 2,500 volts. which means the cable in the pic will be plenty big enough. The higher the voltage the lower the current draw. Lower current draw means smaller wire needed.

The inventor maybe a folk hero for trying . However another 30-40 years of inventing is not going to make any more gains than the labs with multi million government grants .
Unless the Almighty adds some new elements to the periodic table . Chemical battery energy density is within a couple percent of being topped out .
 

Not anti green to point out that any kind of chemical battery lacks the energy density for HD use . For aircraft, construction equipment , cross country trucking and farm equipment .
EVs in short trip light duty operation for short commutes is possible but over priced . As a strictly commuter car for round trips to work or shopping . The EV can be made to mostly work .

Everything posted so far has been based on a 600 volt operating system.
Now you are addressing the second option I mentioned.
It would be feasible to deliver the required amps at 2500 volts through the shown cable so once again were back to the question of;
"What voltage do they want a farmer to play with in a muddy field"
You won't catch me anywhere near a cable carrying 2500 volts that may or may not have a nick in the insulation.

Government legislation can not change facts . Problem is there are those who have blind obedience in idealism. They think if they believe in electric everything , rainbows, unicorns and pixie dust. That they can will it into existence along with enough taxpayer funded research.
These same people are also oblivious to pollution that occurs outside the borders of the US and western Europe.

B&D please advise how the people who are apparently "oblivious to the pollution outside of our borders" would go about doing something about it. I don't think that they allow firearms on airplanes.
 
And how far does the dragline move in a day ? What about when we road the tractor 50 miles ? Thats a pretty long cord
 
Just wish it away that seems to be the common answer .
Through a few billion dollars at studys should fix the problem
 
They make it sound so great just plug this cord in And all
your problems are over you can even have a community
tractor . Have you ever even driven a tractor in your whole life
besides a lawn mower ?

Snowcrop . You will have to explain how you are tying so many unrelated concepts together . And why the green weenies p!$$ and moan here but not seen or heard in Africa and southern/Eastern Asia .

posted the "long cord" solution.. Does even better than no-cord, it moves the fossil burning generation closer to the tractor, removes the inefficiencies of miles of wiring, transformers, substations, etc. The only thing it didn't do is move the emissions out of "my backyard" & into someone else's backyard. :roll:
