Machinery has amplified the workload farmers can accomplish, and technology has delivered greater efficiencies. Now, autonomy is poised to introduce new levels of productivity and fun.

Different than its technology cousins of guidance and GPS-enabled controls, autonomy relocates the operator to anywhere but the cab.

True autonomy is taking off the training wheels, says Steve Cubbage, vice president of services for Farmobile. It doesnt require human babysitting. Good autonomy is prefaced on good data and lots of it.

As machines are making decisions on the fly, companies seek to enable them to provide the quality and consistency expected by the farmer.

We could see mainstream adoption in five to 10 years. It might surprise us depending on how far we advance artificial intelligence (AI), data collection, etc., Cubbage says. Dont say it cant happen in a short time, because it can. Autosteer was a great example of quick and unexpected acceptance.

The NEXAT is an autonomous machine, ranging from 20' to 80', that can be used for tillage, planting, spraying and harvesting. The interchangeable implements are mounted between four electrically driven tracks.Source: NEXAT

The idea and philosophy behind the NEXAT is to enable a holistic crop production system where 95% of the cultivated area is free of soil compaction, says Lothar Fli, who works in marketing for NEXAT. This system offers the best setup for carbon farming in combination with the possibility for regenerative agriculture and optimal yield potential.

The NEXAT system carries the modules, rather than pulls them, as Fli describes, which allowed the company to develop a simpler and lighter machine that delivers 50% more power with 40% less weight. In operation, weight is transferred onto the carrier vehicle and large tracks and optimized so it becomes a self-propelled machine.

This enables the implements to be guided more accurately and with less slip, reducing fuel consumption and CO2 emissions more than 30%, he says. Because the NEXAT carries the implement, theres not an extra chassis with extra wheels. The setup creates the best precision at a high working width that reduces soil compaction on the growing areas.

In the field, the machine is driven horizontally but rotates 90 for road travel. Two independent 545-hp diesel engines supply power. The cab, which can rotate 270, is the basis for fully automated operation but enables manual guidance.

The tillage and planting modules came from Vderstad, a Swedish company. The CrossCutter disks for tillage and Tempo planter components are no different than whats found on traditional Vderstad implements.

The crop protection modules, which work like a conventional self-propelled sprayer, come from the German company Dammann. The sprayer has a 230' boom, with ground clearance up to 6.5', and a 6,340-gal. tank.

The NexCo combine harvester module achieves grain throughputs of 130 to 200 tons per hour.

A 19' long axial rotor is mounted transverse to the direction of travel and the flow of harvested material is introduced centrally into the rotor and at an angle to achieve energy efficiency. The rotor divides it into two material flows, which according to NEXAT, enables roughly twice the threshing performance of conventional machines. Two choppers provide uniform straw and chaff distribution, even with a 50' cutting width.

The grain hopper holds 1,020 bu. and can be unloaded in a minute. See the NEXAT system in action.

At the Consumer Electronics Show, John Deere introduced its full autonomy solution for tractors, which will be available to farmers later in 2022.Its tractors are outfitted with:

Farmers can control machines remotely via the JD Operations Center app on a phone, tablet or computer.

Unlike autonomous cars, tractors need to do more than just be a shuttle from point A to point B, says Deanna Kovar, product strategy at John Deere.

When tractors are going through the field, they have to follow a very precise path and do very specific jobs, she says. An autonomous 8R tractor is one giant robot. Within 1" of accuracy, it is able to perform its job without human intervention.

Artificial intelligence and machine learning are key technologies to John Deeres vision for the future, says Jahmy Hindman, John Deeres chief technology officer. In the past five years the company has acquired two Silicon Valley technology startups: Blue River Technology and Bear Flag Robotics.

This specific autonomy product has been in development for at least three years as the John Deere team collected images for its machine learning library. Users have access to live video and images via the app.

The real-time delivery of performance information is critical, John Deere highlights, to building the trust of the systems performance.

For example, Willy Pell, John Deere senior director of autonomous systems, explains even if the tractor encounters an anomaly or an undetectable object, safety measures will stop the machine.

While the initial introduction of the fully autonomous tractor showed a tillage application, Jorge Heraud, John Deere vice president of automation and autonomy, shares three other examples of how the company is bringing forward new solutions:

New Holland has developed the first chopped material distribution system with direct measurement technology: the OptiSpread Automation System. 2D radar sensors mounted on both sides of the combine measure the speed and throw of the chopped material. If the distribution pattern no longer corresponds to the nominal distribution pattern over the entire working width, the rotational speed of the hydraulically driven feed rotors increases or decreases until the distribution pattern once again matches. The technology registers irregular chopped material distribution, even with a tailwind or headwind, and produces a distribution map.

The system received a Agritechnica silver innovation award.Source: CNH

As part of Vermeers 50th anniversary celebration in 2021, a field demonstration was held at its Pella, Iowa, headquarters to unveil their autonomous bale mover. The BaleHawk navigates through a field via onboard sensors to locate bales, pick them up and move them to a predetermined location.

With the capacity to load three bales at a time, the BaleHawk was successfully tested with bales weighing up to 1,300 lb. The empty weight of the vehicle is less than 3 tons. Vermeer sees the lightweight concept as a solution to reduce compaction.

In April 2021, Philipp Horsch, with German farm machinery manufacturer Horsch Machinen, tweeted about its Robo autonomous planter. He said the machine was likely to be released for sale in about two years, depending on efforts to change current regulations, which state for fully autonomous vehicle use in Germany, a person must stay within 2,000' to watch the machine.

The Horsch Robo is equipped with a Trimble navigation system and fitted with a large seed hopper. See the system in action.Source: Horsch
