I come from a family of farmers, and some of my family does actively farm.
None of them are wealthy enough or operate large enough farms for expensive self-driving tractors. And I share in their concern about the meta-game here: the consolidation of capital, land, and power over the food supply.
Consumers already have a hard time having any lever against rising grocery costs. Consolidation earlier on in the supply chain is not helping.

My father-in-law operates a "small farm" in Saskatchewan with no employees. The average farm size is pushing 10,000 acres, his is 2,000 acres. (2,000 acres is probably close to the median size, though. Really large farms skew the average).
He's got autosteer on a couple of pieces of equipment. His combine-harvester "only" cost $400,000 (used) compared to the $1M+ ones his neighbors use. As a fraction of $300,000, autosteer isn't particularly significant.
But it's massively useful. During a field operation, there are dozens of things the operator should be monitoring and adjusting in parallel. Pretty much all of these are automated with "idiot lights", but a good farmer is closely supervising. Less attention spent doing trivial things like steering results in more attention spend on deck levelling, rotor speed, pick-up speed, et cetera.

My father runs his own chopping business and his machines aren't automated or self-driven either. For him, it's all about being able to repair the machines himself. He's been a diesel mechanic and farm hand all his life, so if something breaks on a "traditional" harvester or tractor, he knows how to fix it and get it running again.

Who in the grocery supply chain is earning huge profit margins?
As far as I understand, consumers have long benefited from myriad subsidies provided to farmers, too low fossil fuel prices that do not price in externalities, too low water prices that deplete aquifers quicker than they can recharge, and extremely cheap labor due to cheaper labor in less developed countries and government looking the other way on farms that hire illegal immigrants.
If anything, the mechanization of farms is the only force pushing food prices lower. Before that, it was the advent of the Haber-Bosch process which drastically increased yields.

4 years ago: "These electric self-driving tractors could make farming much greener"
Driverless tractors may allow for bigger, heavier machines which would be better yet. The bigger the better because soil compaction goes up at a sub-linear rate to weight. While the soil compaction is worse for a heavier tractor where it touches the soil, the heavier tractor can handle a wider pass which means it overall doing much less damage vs a smaller tractor that would need to do several passes touching more soil to get the same work done. This is also why tracks are often worse than tires - even though tires compact the ground more where they touch the soil, the track touches more soil in a turn and thus does more damage in a turn than you save in the row!
Of course different soils are different. You need to discuss the particulars of an individual field before you can make a judgement on what is best. But overall bigger is better.
aaronbaugher · 2h ago
Tractors are made heavy for traction (hence the name), not for safety. In addition to the weight of the tractor itself, fluid is often added to the tires for extra weight, and weights added to the front for more traction and to keep the front down when pulling a heavy load.
You can gain some traction by going from tires to tracks, as some modern tractors do, but you still need a certain amount of weight or you're just going to spin when you're trying to pull a 30-foot-wide chisel plow through soil and last year's stalks.
Going fully autonomous might make tractors a little cheaper, if they don't need A/C and mirrors and things like that, but not lighter. And they'd still need the human stuff for occasions when it can't drive itself anyway, like moving it around the barn lot or going down the road to the next field.
vorpalhex · 1h ago
Can you reduce the weight if you go slower? I realize there is still a floor threshold here.
Optimizing for time matters when paying people is involved but machine costs don't matter so much per hour.
adregan · 2h ago
Surely the weight of a tractor pales in comparison to the person sitting inside? The heavy weight is for that big engine with a lot of torque. Can a lighter weight tractor pull its load?
Kirby64 · 2h ago
I’d assume all the functionality inside the cab, the space needed, seat, controls, windscreen, AC inside the cabin, etc, add up to quite a bit of weight. If you went truly driverless without a cabin you could save a ton of weight.
bluGill · 2h ago
Maybe a ton at the most - but the tractor weights far more than a ton. Actually more weight is a good thing in tractors because that allows for more traction.
Kirby64 · 2h ago
More weight over specific areas is good. By removing weight from the cab, you can add it in places you actually want it. I.e. over the wheels.
bluGill · 17m ago
Tractors are not cars - weight balance doesn't make nearly as difference. Between lower speeds, lack of suspension, and all wheel drive it doesn't matter.
Kirby64 · 12m ago
Weight balance absolutely makes a difference. If you don’t have enough weight on the front of the tractor, for instance, certain implements are nonfunctional. You need to balance weight from front to back. Standard issue parts of tractors is adding weight boxes to either the front or back of the tractor to balance the weight of the implement on the other side.
bluGill · 4m ago
Fair enough - but the humans and the need for a cab is not significant. Those weights are still added based on the implement, and removed for other operations. They are also heavier than the cab + human in many cases. They are also added in front of the front axle, or behind the rear, while the human weight affects both axles (not evenly, but close enough)
hollerith · 2h ago
Is that really true? The heavier the tank, the more often it gets stuck and needs to be pulled out by other vehicles.
saalweachter · 2h ago
Tractors tend to spread their load with more, gianter, wider tires.
The trade-off for making the tractor larger is that you can pull wider and multiple or multi-function implements to do the entire thing faster in one pass.
The larger contact patch for having an absurd number of wheels reduces soil compaction and reduces the chance you get stuck; working in fewer passes further reduces soil compaction and prevents you from getting stuck (since in the ideal case, you're doing one pass on solid ground, and never driving over tilled soil).
bluGill · 2h ago
Tractors get stuck when they drive in mud (and other mud like soils) all the time. However when driving on not-mud it is true. That is the trade off, the heavier you are the more care you need to take about mud.
I suspect tanks get stuck often in part because that is fun and in part because they need to train troops how to get them unstuck and so they intentionally send tanks into mud - which is to say in a real war the generals might (should) avoid getting stuck, but in training it is important to get stuck often. I'm not a military expert though, but that is my opinion on tanks.

Even a small utility tractor is over 10,000lbs
scythe · 2h ago
What you could achieve with a driverless tractor is using two smaller ones instead of one big one. Since the driver's effective wage leaves the cost equation, the number of tractors can potentially be much larger.
Come to think of it, this might also benefit small landholders eventually by reducing the minimum amount of land required to fund a single tractor.
bluGill · 2h ago
I can't figure out how to link, but if you search me you will see elsewhere that I explained that bigger is better for the soil.
Most small landholders should sell and move to the city. You need a fair amount of size to make a decent living selling something cheap. Though my biggest worry is the medium sized farmers - wasting $10/acre in extra chemicals when you have 600 acres is only $6000 - you probably won't even notice it and in any case not wasting it costs investment too. When you have 6000 acres though that $10 is a larger number and you can afford to put a lot of money in better whatever to not waste it.

There might be a very important difference between automation pursued because we don't have enough workers to do all the work we would like to see completed, and automation pursued because it is cheaper for the gigantic corporations who will profit from employing fewer workers. But since we are still in the phase where there are too many jobs and not enough people to do them, I think we don't have to worry about those yet. We should revisit this issue in 300 years.

Farming is one of the hardest jobs out there. You need to effectively run your own business on fine margins often relying on government subsidies which can change over time, with a lot of risk due to crop failures/livestock disease (culling can be necessary for chickens due to bird flu etc). It requires hard manual labour running the farm with physical risk to you if you work with livestock. Cows don't care if you get sick, they still need cared for no matter what, there isn't much space for holidays or illness. This isn't to mention the few times of the year the tractors are used as you describe, but most tractors aren't this fancy, and how would you like to spend all day every day for a time working the land with the tractor from sunrise to sunset?
bluGill · 2h ago
Most farm jobs are not sitting in the tractor all day. There are only a few farms in the world where a tractor has someone sitting in it all day every day. Most farms the tractors are used for 80 hours a week just a couple weeks per year (planting and harvest time). The rest of the time the tractors sit in the shed. There is a lot of non-tractor jobs farmers do. Many of the farms where the tractor is used full time every day the tractor is just pulling the harvest wagon and the crops are harvested by hand - one person drives the tractor while 30 walk behind it harvesting the crops.
The autonomous tractors are for use in fields where there are no other humans (at least so far)

what are the goals of the policy of banning autonomous tractors?
I imagine it is at least twofold:
a) provide jobs for manual laborers
b) more of an equal playing field between large-scale industrial agriculture companies and "sole proprietor" farmers
EDIT: turns out to be a case of safety regulation written before more recent advances in tractor automation. So my guesses were wrong.
The actual regulation in question is part of CA's state-wide agricultural safety code...
(b) All self-propelled equipment shall, when under its own power and in motion, have an operator stationed at the vehicular controls.
It's been in place since the 1970s. At the time it was passed, it was probably reasonable to require a human operator at the controls at all times.
The law is just an anachronism that the state legislature should remove/update.

I wonder how the law is written? Could you have a set of vehicular controls in Kenya remotely hooked up to control it? And then you only pay kenyan not US labour rates?

The video says the regulation was written 50 years ago, and just says "operators must be stationed at the controls". Autonomous tractors were not commercially available yet, it's just a well-intentioned safety regulation that needs to updated now.
tantalor · 3h ago
Does it define "stationed" and "controls"?
If the automated tractor is remotely controlled by my smartphone (IANAF) in my pocket, does that count?
It says: "All self-propelled equipment shall, when under its own power and in motion, have an operator stationed at the vehicular controls. This shall not prohibit the operator occupying or being stationed at a location on the vehicle other than the normal driving position or cab if controls for starting, accelerating, decelerating and stopping are provided adjacent and convenient to the alternate position."
So you do explicitly need to be physically on the vehicle at all times while it's moving.
It has further rules for remotely operating "Furrow guided self-propelled mobile equipment" (which is not how modern autonomous tractors work), but even for those you need to be actively watching it and have immediate access to steering and braking controls.
tantalor · 3h ago
This seems to open the door to operators not being literally in the driver's seat.
I think "location on the vehicle" could reasonably be interpreted as including virtual locations. For example a drone operator is physically in a little room somewhere but they are in actuality operating controls that fulfill all of those requirements remotely. It's not hard to go from there to "I can press the stop button on my phone whenever I want" so I am effectively "stationed at the vehicular controls".

There is no “autonomous tractor law”, the headline is misleading. There is a farm safety law that has been in place since long before any autonomous production farm equipment existed which prohibits self-propelled equipment without the operator seat occupied at all times while in operation. It was not unheard of for people to get on and off low-speed self-propelled (that was not self-driving) farm equipment while in operation, in an attempt at efficiency/multitasking, with attendant safety risks. That’s what the law was directed at.
aaronbaugher · 2h ago
Also, it's useful to remember that before tractors, there were horses, and the equipment pulled by horses was gradually converted to tractors. With horses, the farmer might sit on the equipment and use reins, or he might walk in front of the horses and lead them. Either way, he had control of them without literally sitting on them. So when the first tractors came along, it probably wasn't automatic to think you needed to sit directly on it. And it was a lot easier to hop on and off them when they were small machines without cabs. They were pretty dangerous, really, with little in the way of safety protection over moving parts, so I can see why people thought a rule was needed to keep the driver on the seat.
9cb14c1ec0 · 3h ago
Not only that, but if a tractor encounters an obstacle in the field that it doesn't know what to do about, it can simply stop right where it is and wait for human intervention, unlike cars where you don't want them stopping dead in the middle of the road. Also tractor speeds in fields are far lower than cars on roads, so automatically a huge safety advantage there.
aaronbaugher · 3h ago
Until you get to the end of the field. If a malfunction means you don't turn or stop, the next thing in front of you might be a house, a school, or a highway. Today's farm tractors are powerful, heavy machines that can plow right through a lot of obstacles. I'd want to have a couple extra layers of fail-safes, and probably a human overseer with a kill switch. That could be someone watching a bunch of tractors remotely on monitors.

GPS (or GNSS in general) is hardly sufficient for anything safety critical. The signals are very weak and can easily be spoofed or jammed. Even overhead obstructions like trees and buildings nearby can cause significant offsets due to multipath reflection issues.

RTK driven tractors are not using just standard GPS. They have positional accuracy down to one inch.

Simple solution for that. If you jam GPS and it makes an autonomous tractor run over a school, you're liable for the manslaughter of the school kids. Trains can be derailed, but they're still allowed to operate and we just put the derailer in prison. And knives can be used to stab people. And someone can even grab your arm and force you to stab someone with the knife, and the law understands this.

Perhaps they can be, but will they be when large corporate farms cut corners on things like maintenance?
I started driving tractors when I was 10, and I've been in a couple situations where equipment failure required some quick action to get stopped before serious damage was done. Shit happens, and should be expected to happen and prepared for.

Perhaps it was written to protect jobs or there was subconscious fear over killer machines later epitomized by the film Maximum Overdrive (1986).

Its not a ban on autonomy, which didn't exist at the time to ban. It was directed at people trying to maximize use of their time by getting off slow moving, non-autonomous, equipment to do other things and then climbing back on when needed to make course changes.
It also functions to ban unattended autonomous vehicles now that they do exist, and it may need to be adjusted to allow for an appropriate regulatory framework for limited and safe use of unattended autonomous vehicles, but that was not a subject of concern when it was written.

Perhaps they can be, but will they be when large corporate farms cut corners on things like maintenance?
I started driving tractors when I was 10, and I've been in a couple situations where equipment failure required some quick action to get stopped before serious damage was done. Shit happens, and should be expected to happen and prepared for.
1. Prohibit large companies from using their size to negotiate prices, like how it used to be
2. Stop farm subsidies for all but the most critical areas. If you want to make food available to the poor, give them food stamp cards, but further restrict junk food. Supply side subsidies just create excess crops which lead to everyone trying to use cheap corn in some way. This cheap corn is then used to destroy local farmers in Latin America, further increasing illegal immigration and the power of cartels over a newly destitute population.
Example: corn burning furnaces.

It also functions to ban unattended autonomous vehicles now that they do exist, and it may need to be adjusted to allow for an appropriate regulatory framework for limited and safe use of unattended autonomous vehicles, but that was not a subject of concern when it was written.
It's very hard and time-consuming to repeal/replace a law. It's at least 10x easier to make a "technical fix"/"clarification" that preserves the original intent while removing the unintended effects. That's what should be done.
So yeah, let's let giant farm tractors, larger and more dangerous than (non-firing) tanks from WWII, roam fields nationwide.
