DJI Agras T70S
About the DJI Agras T70S
DJI Agras T70S is a China-market agricultural aircraft identified as model 3WWDZ-U50D in DJI manual v1.2 (2026). DJI lists 53 kg (two nozzles + DB1580 battery) as the specified two-nozzle configuration, a 50 L spray tank and 103 kg (two nozzles) / 107 kg (four nozzles) maximum spray takeoff weight near sea level. The same manual separately lists 127 kg in spreading mode and 122 kg in lifting mode; these installed systems and limits must not be treated as one universal configuration. Its published hover reference is 6.5 min at 103 kg with 30,000 mAh battery. DJI RC Plus 2 AG O4 signal ratings are up to 7 km FCC, 5 km SRRC or 4 km MIC/CE at 2.5 m aircraft altitude, unobstructed and interference-free. The manual lists IP56 protection under its stated conditions; verify the exact regional aircraft before purchase or service.

Common Failure Modes
Symptoms: Uneven application, pump warning, auger blockage or lifting-system alert.
Likely areas: installed tank, nozzles, pumps, spreader, lift hardware and wiring
Identify the installed system and follow chemical or load safety precautions before selecting parts.
Symptoms: Arm deformation, propeller damage, loose motor mount or vibration after impact.
Likely areas: arms, motors, propellers, landing gear and connectors
Keep the aircraft grounded until structural and propulsion checks are complete.
Symptoms: Obstacle-sensing alert, terrain-following anomaly or intermittent controller link.
Likely areas: vision/radar modules, antennas, controller settings and environment
Check model identity, firmware and radio region before selecting replacement parts.
Repair Notes
This English page interprets DJI 2026 China-market documentation for T70S; do not apply other Agras model limits without verifying the label.
Spraying, spreading and lifting use different installed systems and weight limits. Follow the DJI Agriculture app’s recommended load.
Treat IP56 as a scoped test rating, not permanent protection for every aged seal or accessory.
Remove the battery, isolate chemical residue, and confirm exact part numbers and written service scope.
