The explanation was disrupted satellite positioning: solar activity disturbed the ionosphere, which can distort GPS signals on their way to Earth. The phrase “demon possessed” was a farmer’s description of the behavior—not evidence of a hack or anything supernatural.
What happened to the tractors?
In a report published December 12, 2024, Futurism described farmers’ accounts of erratic tractor behavior during a May solar storm that coincided with planting season. Elaine Ramstad, an aurora chaser, said relatives called her during the May 10 storm because their tractors were behaving unpredictably. She said her GPS was “off by close to a foot” during the day, and that “By nightfall, there was no controlling the Autosteer.”
Ramstad summed up the experience this way: “Our tractors acted like they were demon possessed.” That vivid line describes what the machines seemed to do; it is not a technical diagnosis.
How can a solar storm affect tractor GPS?
GPS satellites send radio signals that receivers on Earth use to calculate position. Solar eruptions can send charged particles toward Earth, changing conditions in the ionosphere—the region of the upper atmosphere that those radio signals pass through. A disturbed ionosphere can delay or distort the signals, making a receiver’s position estimate less reliable.
#1 Best Overall
- SMART GNSS GUIDANCE & AB LINE PLANNING – Set your field boundary and working width, then let the system generate guidance lines, record driving tracks, and show real-time deviation alerts. Helps you keep straighter passes, reduce overlaps and skips, and work with more confidence in large fields
- MULTI-GNSS, MULTI-FREQUENCY POSITIONING – Supports GPS, GLONASS, GALILEO, and BDS for stable satellite positioning in field operations. The large 9-inch display shows guidance lines, field boundaries, tractor position, and route direction clearly at a glance
- SAVE FIELDS & TRACKS FOR REUSE – Record, name, save, and recall multiple fields and task routes for repeat seasonal work. Easily return to previous field boundaries and guidance tracks for plowing, seeding, spraying, fertilizing, mowing, and other field tasks
- FAST SETUP & WIDE TRACTOR COMPATIBILITY – Designed for most tractors with a suitable metal mounting surface and cab window. The magnetic GNSS antenna mounts outside, while the suction-cup monitor bracket attaches inside the cab with no drilling required. Set up in about 3 minutes and move between machines when needed
- BUILT FOR REAL FARM CONDITIONS – The outdoor GNSS antenna is built to handle rain, dust, mud, and tough field environments, while the monitor stays protected inside the tractor cab. Clear on-screen guidance helps operators stay on track during long working days and low-visibility conditions
A tractor using GPS for precision navigation depends on that position estimate. Autosteer systems use it to guide the vehicle along a planned line; other farm tasks may use positioning data for mapping. If the data is inaccurate, the system may guide the tractor incorrectly or struggle to maintain its intended path. The reported stopping, weaving, or loss of control is consistent with unreliable positioning, rather than evidence that a tractor was hacked.
Why unreliable positioning matters on a farm
GPS is not just a map display in precision agriculture. It can guide steering and support tasks such as yield mapping, so a positioning error can affect how equipment behaves while working. John Deere service manager Ethan Smidt estimated in the 2024 report that 80 percent or more of Midwest farmers use at least basic GPS for something, such as autosteer or yield mapping. He also estimated that at least 50 percent use GPS on every machine all year.

- Complete Tractor Guidance System: Includes stable software to guide tractor along AB lines, featuring a 7 inch waterproof navigator display with high-precision GNSS Board, high precision GNSS GPS Antenna, and all necessary accessories cables and tools
- Smart GNSS Guidance & AB Line Planning: Generates straight AB lines or curve paths based on your field boundary and working width, records driving tracks and provides real-time deviation alerts to keep passes straight at night or in low visibility conditions
- Multi-Frequency Positioning (L1L5): Large 7 inch screen displays guidance lines, field boundaries, and tractor position in real time. The L1L5 multi-frequency module delivers higher accuracy and more stable signals than single-frequency GPS, keeping every pass on track even near trees or buildings. The device needs to be connected to either a cell phone hotspot or a personal mobile network
- Wide Application Compatibility: Tractor GPS navigation system can be widely used for sowing, cultivating, trenching, ridging, spraying pesticide, transplanting, land consolidation, harvesting and other work scenes. Suitable for John Deere, Case IH, New Holland, Massey Ferguson, Fendt, Kubota, and most tractors. Suction-cup tablet bracket mounts on cab window with no drilling required. Swap between machines in approximately 3 minutes
- Google Maps & 48 Languages: Built on Google Maps for use in most regions worldwide, suitable for international farms or contractors. 48 language options let operators work in their native language, reducing training time and errors
Those figures are Smidt’s estimates, not results from a nationally representative survey or an independent equipment audit. They nevertheless illustrate why a disruption can matter during a busy planting period: many farms rely on GPS for more than one task.
What can farmers do when GPS guidance is unreliable?
The report documents farmers’ experiences but does not establish a particular backup procedure, product, or mitigation as effective. In practical terms, if a tractor’s position or autosteer behavior appears unreliable, the key issue is that automated guidance can no longer be assumed to reflect the machine’s true position. Farmers need to follow their equipment maker’s operating guidance and use an appropriate alternative way to control the machine rather than treating questionable GPS guidance as dependable.

The report does not name a tractor model, receiver, correction service, or field-tested backup system, so it does not support recommending a specific product or claiming that one navigation setup would have prevented the incident.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Was it an alien signal, a hack, or a solar flare?
The “signal out of space” in the headline refers to solar activity, not an alien transmission. The reported explanation is that storm activity disturbed the ionosphere and affected GPS signal propagation. The account does not indicate that the tractors were hacked, and “demon possessed” is figurative language for unpredictable machine behavior.
