There are dozens of farm service companies in agricultural areas because the reality is no farmer needs the same equipment 24/7/52.
For example, if a farmer needed his 400 hp articulated tractor going
0.5 mph 356 days out of the year then he'ld be working about 10 feet^2 / sec.That 774 hours or over 3 months of 8 hour days to complete just one square mile.

Then to do just one square at 0.5 mph:
Diesel: 17,000 gallons.
Diesel cost today: $85,000
Assuming the price of liquid fuel continues to increase at "only" 30% a year:
Diesel cost in 2 years: $145,000
Diesel cost in 6 years: $425,000
And that's just one one time operation.
It's a whole lot cheaper to electrify, even if you have to buy 14,000 laptop batteries (twice that of the 200 kW Tesla) and install them yourself.

Do you actually kno what no till agriculture is?
Hint, it involves a sod seeder instead of a combine & ploughing.
Just another tool in the fight against obesity.
Err, is this something to do with fast charging? Heard 110% for C/10 in dep-discharge lead acid batteries, but not that much.
notie this paragraph after I flicked the other answer....
So instead of 415V supply, you just tap the 11Kv lines instead.
Lol, the problem with this idea is that farmers producing the same crop generally all do the same job at the same time.
Actually, your system might work better if the tractor camewith a pair of swappable battery packs that you dock in and out of a charging station.
It would certainly help the economics by reducing the peak power demands.
What'll happen is they'll get together more often, i. e., public transportation, and eat even more.

The OP issue is the tens of billions a year unnecessarily wasted on diesel for agriculture.
That's the context, the _only_ reason for electrification of farms.
Are you just acting dumb or are you really this stoopid?
Bret Cahill
You _want_ to go Rube Goldberg?
If your goal is to cost farmers more money then that explains a lot.
Bret Cahill
Still trying to dodge the OP issue, the cost of diesel fuel?
Are you just acting dumb or are you really this stupid in real life?
Bret Cahill
Which is trivial merely by wiring in more batteries in parallel.
Are you just acting dumb or are you really this stupid in real life?
. . .
The real savings appear in the energy intensive operations.
The more energy intensive the operation, the bigger the savings from moving from diesel to batteries.
If you go to less energy intensive operations, say a garden tractor, it is of course cheaper to go Li-Ion instead of liquid fuel, but the absolute savings aren't all that great.
Are you just acting stupid or are you really a moron in real life?
Bret Cahill
The cost of liquid fuel compared to grid-battery is the only reason to discuss the electric tractor.
If you try to weasel out of the relative cost of diesel vs grid- battery everyone will know you're a loser as well as a moron.
There is one reason and one reason only to discuss the cost of grid- battery energy:
To compare it with diesel.
To win this debate you'll need to show how diesel power is cheaper than charging batteries and running an electic motor off them.
You cannot so you will try to dodge the issue of diesel costs altogether.
Bret Cahill
Another argument for grid battery tractors. For longer higher power applications, all you really need to rent _or_ buy is another battery in parallel.
There is just no situation where diesel is more cost effective than grid battery.
Not in energy costs, not in labor costs, not in capital costs, not in maintenance costs.

Since you persist in being an obstinate mule regarding proper posting form, I don't know to whom you are responding or addressing.
IMHO you are the stupid one for posting this off-topic crap to the s.e.b. Newsgroup.
I mentioned that here last summer. It might take 2 - 3 dozen large expensive battery packs.
But I don't deny even that might eventually be more cost effective than diesel.
The cheapest fastest way to go now is the trolly wire - battery "hybrid."
Batteries can be wired in parallel for fast recharging. So the guy pauses a minute or so at the end of the field . . . no biggie. His job is to make money and he can no longer make money burning 2-oil.
If they are using lasers and GPS they can plow at night. TVA has 7 GW available at 7 cents / kW hr. at night, about 1/4th the cost of diesel power
The SW will soon have a lot of solar anyway.
Bret Cahill
Put out the shoe and the idiots step right in.
Did you miss the response?
That the more diesel the tractor burns the more cost effective it is to switch to battery-grid electric tractors?
Are you just acting dumb or are you really this dumb in real life?
