2026 Software Release Notes

Software v3.509

• Improved GNSS resilience

This release improves how FD20 handles rare, adverse signal processing from SWIFT GNSS modules.

• Straighter rows at the start of each pass​

Improves alignment and reduces the “snake-like” effect when beginning a new pass.​

• Faster seeding performance

Enables increase in speed for smaller seed distances up to 20% while keeping the existing max speed at 950 m/t.

• Battery management optimization​

Updated battery protection settings to improve reliability and align with the latest battery system standards.​

• New crop type selection feature

Allows crop type to be selected during field setup, preparing the system for improved reporting and optimized settings.​

• Residue cleaning feature

To clean weeding wires and soil tools from weed residue, a feature is added to reverse robot direct with tools in ground.

• Improved robot behavior at the field corners

Improved route calculation and timing of weeding tools lowered.

• Main fuse protection

Robot speed is reduced when consumption is too high to minimize risk of blowing fuses at peak motor loads.

+Spray v2.018 related to Software v3.509

• Improved flow measurement logic for more stable flow measurements
• Flow surveillance values in HMI & telemtry for performance check and easier fault finding
• Allow direct change of calfactor without need to run calibration

Note: Use +Spray application planner version 1.4 due to changed minimum allowed nozzle opening timings (minimum allowed water rates)
