Open Source Farming Equipment is vital for farmers

Excerpted from KYLE WIENS:

“There’s not much you can do with modern ag equipment. When it breaks or needs maintenance, farmers are dependent on dealers and manufacturer technicians—a hard pill to swallow for farmers, who have been maintaining their own equipment since the plow.

“[DIY repair] is cheaper than calling out the technician. But that information is just not out there,” Dave explained to me.

The cost and hassle of repairing modern tractors has soured a lot of farmers on computerized systems altogether. In a September issue of Farm Journal, farm auction expert Greg Peterson noted that demand for newer tractors was falling. Tellingly, the price of and demand for older tractors (without all the digital bells and whistles) has picked up. “As for the simplicity, you’ve all heard the chatter,” Machinery Pete wrote. “There’s an increasing number of farmers placing greater value on acquiring older simpler machines that don’t require a computer to fix.”
The problem is that farmers are essentially driving around a giant black box outfitted with harvesting blades. Only manufacturers have the keys to those boxes. Different connectors are needed from brand to brand, sometimes even from model to model—just to talk to the tECU. Modifications and troubleshooting require diagnostic software that farmers can’t have. Even if a farmer managed to get the right software, calibrations to the tECU sometimes require a factory password. No password, no changes—not without the permission of the manufacturer.

John Deere, in particular, has been incredibly effective at limiting access to its diagnostic software. Which is why I wouldn’t have been able to tweak the programming on Dave’s tractor, even if I had been able to hack together the right interface. John Deere doesn’t want me to. The dealer-repair game is just too lucrative for manufacturers to cede any control back to farmers.

* Hacking the Family Farm

After a second swear-word-inducing attempt to monkey around in the code that fuels Dave’s computer, I started wondering how other farmers were dealing with the increasingly cloaked and proprietary nature of modern farming.

My failure with Dave’s tractor got me fired up. I started lurking in ag forums, talking to my farmer friends, and hanging out in diesel repair shops. I found out that farmers aren’t taking the limitations lying down. There’s a thriving grey-market for diagnostic equipment and proprietary connectors. Some farmers have even managed to get their hands on the software they need to re-calibrate and repair equipment on their own—a laptop purchased from some nameless friend-of-a-friend with the software already loaded on it. There are even ways to get around the factory passwords that block access to the tECU to effect repairs.

But under modern copyright laws, that kind of “repairing” is legally questionable.

Manufacturers have every legal right to put a password or an encryption over the tECU. Owners, on the other hand, don’t have the legal right to break the digital lock over their own equipment. The Digital Millennium Copyright Act—a 1998 copyright law designed to prevent digital piracy—classifies breaking a technological protection measure over a device’s programming as a breach of copyright. So, it’s entirely possible that changing the engine timing on his own tractor makes a farmer a criminal.

Instead of wrestling with proprietary systems, other farmers are starting to go open source. Dorn Cox has been working the land most of his life. After a break to work in tech start-ups, he took over a 250-acre farm in Lee, New Hampshire. In 2010, he co-founded Farm Hack, an online community of farmers, designers, developers, and engineers “helping our community of farmers to be better inventors, developing tools that fit the scale and their ethics of our sustainable family farms.”

“Knowledge wants to be free,” Cox told me.

So Farm Hack is setting it free. Together, members are building an open-source library of farming tools and knowledge. They hack together solutions that work for them. Projects range from the classically low-tech (a farm bicycle that lets users pick ground crops like strawberries without destroying their backs) to the decidedly tech-savvy (a remote-controlled, Arduino-powered compost monitor).

“The main thing, from a hacker’s perspective, is that we’re not dependent on something to create the tools for us,” Cox explained. “We are actually adapting and taking ownership.”

Unfortunately, when it comes to modifying existing equipment—like Dave’s tractor—it’s that same idea of ownership that’s most contested. Dave paid for the tractor; he owns what’s tangible: the wheels, the metal chassis, the gears and pistons in the engine. But John Deere owns everything else: the programming that propels the tractor, the software that calibrates the engine, the information necessary to fix it. So, who really owns that tractor?

Even if he could, would it be legal for Dave to fix his machine? Right now, we don’t know; and that ambiguity is disturbing. So, we’re trying to find the answer. In conjunction with USC and the Electronic Frontier Foundation, we’ve asked for a DMCA exemption for farmers who want to modify and repair their equipment.”
