Farmers Deserve the Right to Repair Their Tractors

Jun 04, 2021

By Hannah Packman

Thanks in large part to the introduction of machinery like tractors and combines, farms today are far more efficient and productive than they were a handful of generations ago. Though these time- and labor-saving technologies can run tens or even hundreds of thousands of dollars, farmers often aren’t able to fix their machinery themselves – which has significant implications for their finances, privacy, and security.

A few decades ago, any given farmer often had the skills and tools needed to quickly make repairs if their machinery broke down. These days, however, it’s not so straightforward. Most modern farm equipment is technologically advanced, containing computers and sensors that collect and transmit data. As a result, specific software tools are typically necessary to address mechanical failures and other issues.

However, most companies refuse to make those tools available to farmers, making it exceptionally difficult to fix broken machinery on their own. They can’t even go an independent mechanic, since manufacturers won’t sell them parts or diagnostic tools either. This leaves farmers essentially no choice but to take their broken equipment to a licensed dealership.

This isn’t cheap. A farmer might spend thousands of dollars on a simple adjustment they could have done themselves with the appropriate resources. On the other hand, this arrangement has proven wildly lucrative for manufacturers; for Deere, as an example, parts and repairs are up to six times more profitable than selling the equipment itself.

But money isn’t the only problem – it’s also a matter of time. Oftentimes on a farm, tasks like planting and harvesting have to be done within a window of just a few days when the moisture content, ripeness, or weather conditions are just right. If, god forbid, machinery breaks during that window and a dealership can’t make an appointment immediately, the wait can cut severely into the farmers’ annual yields and income.

There’s also the issue of privacy. Equipment manufacturers collect lots and lots of data about soil, weather, yields, and other factors, which they can then share with or sell to “affiliates and suppliers.” This intentional data sharing in and of itself is worrying for farmers’ privacy, but even worse is the possibility of hackers accessing that information. Just last month, a security expert found vulnerabilities in John Deere’s apps that would have allowed outsiders to download the company’s data on farm equipment and vehicle owners.

In addition to data breaches, there are other potential security risks. Because most modern tractors can be operated and shut off remotely, some farmers and experts worry that hackers could disable thousands of tractors at a time. Such a widespread disruption could affect the entire country’s agricultural production, threatening livelihoods and food security.

Video: Turning Plant Defense Into a Management Strategy

Turning Plant Defense Into a Management Strategy

Understanding how a plant responds to stress is one thing.

Using that knowledge to make better management decisions is another.

Systemic acquired resistance, or SAR, is the plant's more direct defense response. When stress or infection occurs, the plant begins signaling throughout its system and preparing defensive compounds.

But if we know that response exists, can we help prepare the plant before the stress arrives?

The answer starts with understanding what triggers the response and what the plant needs to carry it out.

The Trigger and the Fuel

Salicylic acid plays an important role in triggering the SAR pathway.

Think of it as turning the truck on.

The engine may be running, but it still needs fuel to do the work.

In this case, manganese plays an important role in supporting the enzyme systems involved in the plant's defensive response.

This makes manganese status an important part of the conversation. Whether a producer is using tissue testing, sap analysis, or simply scouting for visible deficiency symptoms, the goal is to make sure the plant has adequate manganese available.

Manganese is required in relatively small amounts, but that does not make its role small.

If the plant receives a signal to defend itself but lacks the nutrition needed to support that response, it may struggle to carry out the process efficiently.

The trigger matters.

The fuel matters too.

Prepare Before the Stress Arrives

The best time to think about stress management is before the plant is overwhelmed.

Once a crop is already struggling, management can quickly turn into a game of catch-up.

This is similar to nitrogen management. Once a plant becomes severely deficient, correcting the problem does not necessarily erase the time and yield potential already lost.

Plant defense can work the same way.

Low-rate, targeted approaches designed to support the SAR pathway may fit best ahead of an expected stress event rather than after significant damage has already occurred.

That requires producers to think about predictable stress.

We may not know exactly what the weather will do tomorrow, but we generally know summer heat is coming. We know certain field conditions increase disease pressure. We know a herbicide application can temporarily stress a crop as the plant processes the chemistry.

Even a properly timed and labeled herbicide application can create a temporary response in the plant.

That does not mean the herbicide is bad.

Weeds can create significantly more yield loss than the temporary stress caused by controlling them.

The question is not whether we should eliminate every stressor.

The question is whether we can better prepare the plant to manage necessary and predictable stress.

Not All Stress Is Bad

Stress is a normal part of plant growth.

A perfectly stress-free environment does not exist in the field.

In fact, some stress is necessary for normal plant development. A plant responds to wind, temperature, moisture, sunlight, and countless other environmental signals throughout the season.

The environment is stress.

The plant's job is to manage it.

Problems begin when the stress load becomes greater than the plant's ability to respond.

Extreme heat, drought, high salt concentrations, disease pressure, and even certain management practices can add to that load.

This is where understanding SAR becomes useful.

Instead of waiting until the plant is visibly struggling, producers can begin identifying periods when stress is likely and make management decisions around those windows.

ISR Starts With the Soil

While SAR is a more direct defense response, induced systemic resistance, or ISR, brings the conversation back to soil health.

The longevity of a farm is closely connected to the health of its soil.

Carbon plays a major role because it supports biological life within the soil. Bacteria, fungi, and other organisms interact with plant roots and influence how the plant grows, accesses nutrients, and prepares for stress.

This is why soil health cannot be reduced to one product or one application.

It is a system.

Keeping living plants in the field longer can support biological activity. Cover crops may fit some operations. Better water management can improve soil conditions.
