John Deere partners with Spudnik to replace mechanical driveline with electric motors
John Deere is offering an Electric Variable Transmission (EVT) on its larger 8 and 9 series model tractors that replaces a standard mechanical variable transmission with electric motors. Now, they’re partnering with Spudnik to put the system to work on potato and root crop farms.
Naturally, Deere cites a number of advantages to using its tech — including more efficient operation, infinite speed control, reduced maintenance requirements, and superior torque delivery “to the wheels.” The ag equipment experts at Agriland, however, cite yet another benefit to the EVT that’s often overlooked: off-boarding.
“(One of) the virtues of this (EVT) approach is getting power to the wheels … but another notable benefit of this arrangement is that an electrical power source is readily available to drive implements, which is now generally referred to as off-boarding,” writes Justin Roberts. “The various driveshafts and belts on a trailed machine, such as a baler, can be replaced with wires and motors which are lighter and do not require the heavy engineering necessitated by tensioned pullies and the torque reaction of shafts.”
John Deere EVT cutaway
Deere notes that agricultural implements with powered axles are already successfully used in Europe, where they help to “push” the tractor from behind while working in the field. In addition to improving traction and preventing tractors from getting stuck in inclement weather, the EVT-powered axles theoretically enable a smaller tractor to effectively pull a larger implement.
“This EVT is the industry’s only transmission that enables electric power generation (up to 100kW),” says Ryan Jardon, marketing manager for John Deere. “By using this electricity farmers could power implement fan drives, take the place of implement hydraulic pumps, or assist the tractor by powering the implement’s axles. This is similar, to proven-technology John Deere currently uses, on construction equipment.”
By now, though, you’re probably wondering what any of this has to do with potato farming. It turns out that electrification, whether we’re talking about fully electric drive or a diesel/EVT hybrid, solves a huge problem in root crop harvesting.
Using air to separate roots and tubers from dirt clods and stones is a common practice on mechanical harvesters, but maintaining a consistent airflow with a diesel engine that’s under differing loads throughout its duty cycle, constantly varying engine speeds, and — as a consequence — fan revolutions is a constant problem. Working with Deere, Spudnik has solved this problem by driving its fans with an electric motor that’s powered with off-boarded electricity from the EVT, rather than a mechanical connection to the tractor’s transmission (how it’s been done for the better part of a century).
Electrifying the fan motor means it can run at a constant speed, regardless of how fast, or how slow the tractor is running.
The configuration has already been tested on one of Spudnik’s 6621 2 Row AirSep potato separators with a large grower out in Washburn, Maine with great success, according to Spudnik. No word yet on when they’ll get serious and roll out to Idaho.
Electrek’s Take
John Deere knows that its core buyers are wary of new technology — and even talking about a fully electric tractor is one of those things that could sour a longtime customer relationship in some parts of the country. Deere is doing a smart thing here by developing the EVT, electrifying their ag equipment’s drive units and offering several of the benefits of full electric operation without taking away all the rattling vroom-vroom diesel noises that their current customers love.
Think of the EVT, then, as a PHEV for farmers. Once they understand that they’re already driving an electric tractor and pulling electric implements with electrically driven axles, the only question will be how those motors get the electrons they need to do the work. Will it be from a diesel generator/alternator, as in the EVT, or a battery?
Sooner than later, the sheer economics of battery power will make switching a no-brainer. Until then, clever tech like the EVT is laying the foundations by playing up the benefits of EVs without using any politically charged terms. And— hey, whatever works.

HOUSTON — Amazon, Alphabet’s Google and Meta Platforms on Wednesday said they support efforts to at least triple nuclear energy worldwide by 2050.
The tech companies signed a pledge first adopted in December 2023 by more than 20 countries, including the U.S., at the U.N. Climate Change Conference. Financial institutions including Bank of America, Goldman Sachs and Morgan Stanley backed the pledge last year.
The pledge is nonbinding, but highlights the growing support for expanding nuclear power among leading industries, finance and governments.
Amazon, Google and Meta are increasingly important drivers of energy demand in the U.S. as they build out artificial intelligence centers. The tech sector is turning to nuclear power after concluding that renewables alone won’t provide enough reliable power for their energy needs.
Amazon and Google announced investments last October to help launch small nuclear reactors, technology still under development that the industry hopes will reduce the cost and timelines that have plagued new reactor builds in the U.S.
Meta issued a call in December for nuclear developers to submit proposals to help the tech company add up to four gigawatts of new nuclear in the U.S.
The pledge signed Wednesday was led by the World Nuclear Association on the sidelines of the CERAWeek by S&P Global energy conference in Houston.

French industrial giant Schneider Electric hails the significance of China’s ‘DeepSeek moment’
China’s so-called “DeepSeek moment” is likely to be good news in the global race to develop artificial intelligence models that can carry out more complex tasks, according to Jean-Pascal Tricoire, chairman of French power-equipment maker Schneider Electric.
“I actually think its good news. We need AI at every level,” Tricoire told CNBC’s Steve Sedgwick at CONVERGE LIVE in Singapore on Wednesday.
“We need AI to optimize your whole enterprise at all levels, so that you can buy better, consume better, decide better, source better. To do all of this, we need models to operate on a smaller scale,” he added.
Tricoire said the emergence of Chinese AI app DeepSeek showed that AI models can achieve the same results as some of its more established U.S. rivals, but with a much smaller model.
It “will actually spread AI at all levels of the architecture much faster,” Tricoire said. He added that DeepSeek’s blockbuster R1 model would be “fantastic” for improving safety and reliability when deploying AI on dangerous equipment.
“The spread of AI models at every level of what we need is actually very good news,” Tricoire said.
His comments come shortly after Schneider Electric reported record sales and profits in 2024.
The company, which has been a big beneficiary of the artificial intelligence trend, raised its 2025 profit margin following robust fourth-quarter demand for data centers.
Shares of Schneider Electric rose 33% in 2024, following a 39% upswing in 2023. The Paris-listed stock is down around 7% year to date, however, with China’s recent AI push sparking concerns about AI investment and tech sector returns.
Data centers, which consume an ever-increasing amount of energy, represent a key piece of infrastructure behind modern-day cloud computing and AI applications.
