Farmers Struggling With High-Tech Farm Equipment
An anonymous reader writes: Farming is a difficult profession. One of the constants throughout the generations is that if you're working out in the field all day, machinery eventually breaks down. Farmers tend to deal with this harsh reality by becoming handy at basic repair — but that strategy is starting to fail in the digital age. Kyle Wiens, founder of iFixit, writes about the new difficulties in repairing your broken tractors and other equipment. Not only do you often need experience in computer software, but proprietary technology actively blocks you from making repairs.
"Dave asked me if there was some way to bypass a bum sensor while waiting for the repairman to show up. But fixing Dave's sensor problem required fiddling around in the tractor's highly proprietary computer system—the tractor's engine control unit (tECU): the brains behind the agricultural beast. One hour later, I hopped back out of the cab of the tractor. Defeated. I was unable to breach the wall of proprietary defenses that protected the tECU like a fortress. I couldn't even connect to the computer. Because John Deere says I can't." Wiens also tells us about Farm Hack, a community that has sprung up to build a library of open source tools and knowledge for dealing with high-tech modification and repair in agriculture.

This is likely one of those cases where the manufacturer is not to blame, instead it is likely federal regulations that require these systems to be locked down and only adjusted by authorized personel, I know this is the case with many new industrial engines where emissions compliance requires that field technicians no longer be able to adjust certain parameters, instead all these settings are locked down at the factory.
If the demand is really there, then go fill it.
SJW's don't eliminate discrimination. They just expropriate it for themselves.
As a current IT guy who grew up on a large farm in the middle of nowhere, I can confirm that this is true. I've seen the dramatic changes and advances that technology has brought to the agricultural world, and almost universally it has been implemented such that you don't really own what you really own. Proprietary software, interfaces, programs, hardware -- you name it. And...it's not just tractors, combines, or other mechanical items -- it includes software/hardware to automate feeding lots, climate controls, GPS integration, etc. There's little to no open source, open specifications, API availability, or comprehensible documentation available. It's a clusterfscking nightmare, and requires you to take anything that breaks or malfunctions to a certified dealer to have them (and only them) work on it for whatever they deem the price to be that day.
Now there are some really amazing advancements that have come along in agriculture over the past 20 - 30 years, but in many ways technology is turning the clock back on American agriculture and making it into the modern indentured servant model, especially when you add in all the BS that Monsanto has brought/caused in the agriculture world. I feel bad for my family as well as other farmers today.
Most 'farms' in america are part of multinational food corporations like Cargill and ADM. They have motor pools to repair fleets of farm equipment like tractors and harvesters. firmware updates and engine maintenance are often performed by representatives of the companies that manufacture the equipment. IT and information systems departments handle things like GPS and computer software and hardware related to the harvest. small, agrarian farming is almost obsolete in America unless you look into how poulty and pork are raised. In these cases its small contract farmers working for larger entities like Hormell. Even these small farmers though are forced into the disposable economy of modernization that takes them out of the direct path of machines they can work on.
Growing up on a farm in Ohio I remember having to weld equipment back together. I remember cleaning carbureators, hammering out feeders, and changing fluids. It was not fun, and it often meant drastic inefficiencies like having to leave hay out too long or work two days straight trying to get things in order after a break. In a lot of ways modern equipment is more resillient and not as prone to problems. these engine computers save a ton of fuel and effort. coupling, power takeoff, gears, speed, you name it and its probably in the hands of the computer. If i had to do it all over, I'd miss my old ford tractor but i wouldn't miss how it sputtered in cold weather.
Good people go to bed earlier.

They would go broke. The reason all of the sensors are there is because when they didn't have sensors, and some farmer misused they tool and got hurt, they sued the manufacturer and won lots of money. So now there are sensors to make sure you have a bum in the seat, that you don't back up with blades engaged, etc., etc. Nothing is easy to maintain anymore because society no longer wants individuals to take responsibility for their own poor judgment.
There is a difference between what a manufacturer should be responsible for and what an owner should be responsible for. For example: Engine throws a rod, causing shrapnel to injure operator. Manufacturer is responsible. Another example: Equipment allows operator to get off and stroll around in front of equipment and operator gets run over. Operator is responsible. Unfortunately, when operators misuse equipment through poor judgment, the courts side with the operator, so the manufacturer is forced to remove functionality from all users because one user is unable to exercise the commons sense required to operate the machinery.
If you are not allowed to question your government then the government has answered your question.
BMW tried that. they specify a "special" oil for their cars and bikes. Luckily there are people that have higher IQ's than BMW engineers and you can use cheap synthetic 5W30 oil at a sane 7500mile oil change interval and be better off than their special BMW LL-01 at a 15,000 mile change.
Also the BMW canbus, Kbus, and ODB-II is so hacked that you can do anything you want. GM, FORD and ther others also tried to lock down their data busses, but people hack them anyways and release the information.
What is needed is a federal mandate that requlre all vehicle and equipment makers publish full details on their systems freely.
Do not look at laser with remaining good eye.
This is bullshit. The manufacturer wants nothing open because it'll commoditize the stuff that rakes them boatloads of money. Regulation has nothing to do with it. The owner/operator of the equipment is responsible for maintaining it with adherence to emissions regulations. How she does it, is up to them.
A successful API design takes a mixture of software design and pedagogy.
We have have people indoctrinated up to the eyeballs on Slashdot now. Somehow these one trick ponies are going to link whatever the problem is to government regulation.
I spent nearly 15 years in IT before returning to the family farm to work with my brothers. We farm several thousand acres of irrigated land with some large, expensive machines, so I have some experience in this. This article really hits home for me. Forgive some of the jargon, but this is slashdot; you can deal with it.
Coming from the open source world, computer technology in farming, both in the machines themselves, and the software farmers use, is like stepping back in time 20 years or more. Farm software is a niche market, and companies are pretty jealous of their profits. So mapping software is very expensive and interoperability is a bit difficult. Right now I can pull maps off my machines (Case, John Deere), but they each use different native formats so if I want to do any work in QGIS I have to use the company's individual software (which ironically enough is DRMd even though it comes for free with the machine) to export the data in SHAPE format. Software packages like the SMS mapper can read some manufacturers' data files directly because they licensed the formats. But there's very little info out there on hacking these formats and very few open source hackers know enough about farming and these systems to bring expertise to bear.
Even worse, all the companies are talking about cloud-based mapping solutions, but that's even more proprietary and closed.
Companies talk about "open standards" but what they really mean is they export SHAPE files from a computer program. It's really frustrating, but with interest in UAVs, perhaps people will finally crack this barrier.
As to the machines themselves, there are a number of issues. One is government regulations. Adjusting the timing as the farmer in the article wanted to do is extremely illegal and can get you a huge fine from the EPA if you are caught, which you will be. Because unlike in the automotive world, there aren't a any third-party repair shops with access to the parts, let alone diagnostic equipment. Apparently the EPA requires the manufacturer to report any deviations from the the approved program, and they levy fines. Sounds orwellian, but the EPA doesn't mess around when it comes to pollution regs (and I'm okay with that in theory). Suppose the manufacturers want to cover themselves.
Someone asked why a company can't spring up to develop hackable machines? There are efforts to this effect.

But for larger scale farming, it's harder. In the case of engines, the EPA would simply never allow them to market if the parameters that cause an engine to meet EPA regs are allowed to be changed. Regulatory capture has made modern diesels so expensive to develop now, including licensing patented pollution control technologies like the urea injection systems, that it's cheaper for companies to buy an existing engine than to develop their own. So even if I started a hackable tractor company I'd still need to use an engine with an extremely proprietary ECU, and would have to license canbus info to simply connect a transmission to the engine.
The other part of machines that is jealously guarded is the main canbus that links everything on the tractor. We're talking engine control, transmission control, hydraulic remotes, cab systems, and most importantly, the GPS receiver, guidance computer, and steering valve. The commands that flow on this bus are not yet encrypted (they will be soon, starting in cars I predict), but they are highly proprietary and protected by NDAs. You'd think that with a modern tractor I could take anyone's GPS receiver, mate it with anyone's guidance computer, and control any tractor's steering. Well it's not like that. On John Deere, for example, if I want to use anything other than GreenStar for GPS and guidance (a $10-$20k touch by the way, plus yearly fees for RTK), I have to physically replace the steering valve system with one that the 3rd party system is compatible with. There was a company that rev

Remember way back when if you bought something you owned it and could do with it what you pleased? Good times...

Quit being such a corporate tool.
The tort aspect of this is likely completely irrelevant since these are likely highly self reliant types used to fending for themselves for various reasons. Even in the city, this excuse "but we will get sued" is usually just bullshit. Lazy people are just trying to take advantage of the pervasive anti-lawyer propaganda.
Quit swimming in the kool-aid.

I've had the same experience with a 1954 Massey-Ferguson. I've never worked on a farm tractor in my life, only small engines and cars. Yet I could tell it was designed to be disassembled in the field.
All the panels were held on securely, but with a minimum of screws. 10 screws, and I had the entire engine cowling and side panels removed. The front debris screen was actually hinged by the cowling! The radiator was held on with two massive bolts, making it a cinch to remove, all right in the middle of the lawn.
Repair and reassembly was just as simple, and easily accomplished by just myself. I went from dead-in-the-field to full operation in about 2 hours, with nothing more than 1/2, 9/16 and 3/4 sockets and a flat-head screwdriver.
And again, I'd never worked on a farm tractor in my life. It was just that simple and intuitive.
