Assisted steering
John Deere has expanded its satellite-guided GreenStar AutoTrac assisted steering to 8020 Series MFWD and Independent Link Suspension wheeled tractors.
The system was introduced last year on the 8000, 8010, 8020, 9000 and 9020 series track tractors.
GreenStar AutoTrac is an assisted-steering system that uses the three common components: GreenStar display, mobile processor, and StarFire position receiver with SF2 differential correction subscription.
This assisted steering system is accurate to within four inches pass to pass and guides the tractor in a straight line. The operator still turns the tractor at the end of each pass, and must also steer around obstacles such as trees, ditches and waterways.

Nytro Ag Corp and Green Lightning recieved an innovation award at Ag in Motion 2025 for the Green Lightning Nitrogen Machine, which converts atmospheric nitrogen into a plant-usable form.
The system improves efficiency, reduces overlap and operator fatigue and saves fuel.
For GreenStar AutoTrac to work on wheeled tractors, an electro-hydraulic steering system is required. A field-installed kit will be available for 8020 Series tractors with MFWD or ILS.
The component locations and designs are already engineered into these tractors, and installation of AutoTrac is compatible. GreenStar AutoTrac can also be ordered factory assembled on 8020 MFWD or ILS tractors.

Moisture sensor
Lindsay’s new Grow Smart moisture sensor line is designed to measure soil moisture content.
When inserted into an access tube, the portable probe measures soil moisture at up to 16 depths through a crop’s root zone.
Data is shown on a hand-held display unit and is stored for review using Windows-based graphic software.
The remote automated sensing system is for integration with larger operations where individual irrigation systems, usually centre pivots, are controlled by telemeter from a central location.
The Smart Probe has adjustable sensor depths while the EZ Probe has a fixed length.
With either probe, operators can use the GrowSmart FieldSensor Link to transmit moisture data to a field data reporter, where information from up to 50 probes can be stored for downloading in the field or transmitted to a remote computer.
