DJI Agras T70
About the DJI Agras T70
DJI Agras T70 is a China-market agricultural aircraft, distinct from T70P. DJI manual v1.2 identifies aircraft model 3WWDZ-U50B and lists a 50 L spray system, 52 kg listed empty-configuration weight, 102 kg takeoff weight with two nozzles or 105.8 kg with four near sea level. Its separate spreading-mode weight reference is 126 kg; these configurations must not be combined into a single spray limit. The manual lists 6.5 minutes of hovering and 11.4 minutes of maximum flight at 102 kg with a 30,000 mAh battery. DJI RC Plus 2 O4 signal ratings are up to 7 km FCC, 5 km SRRC or 4 km MIC/CE under stated unobstructed conditions. The current manual lists IP56; an earlier v1.1 manual listed IP67, so source version and actual aircraft configuration matter.

Common Failure Modes
Symptoms: Uneven application, pump warning, auger blockage or lifting-system warning.
Likely areas: installed tank, nozzles, pump, spreader, lift system and wiring
Identify the installed system and follow chemical or load safety procedures before selecting parts.
Symptoms: Arm deformation, damaged propeller, loose mount or abnormal vibration after impact.
Likely areas: arms, motor mounts, propellers, landing gear and connectors
Keep the aircraft grounded until structural and propulsion checks are complete.
Symptoms: Obstacle-system warning, terrain-following anomaly or unstable O4 link.
Likely areas: radar, vision, antennas, controller configuration and environment
Verify T70 model identity, firmware and radio region before selecting replacement parts.
Repair Notes
This English page interprets DJI China-market T70 manual v1.2; do not apply T70P or global-market values without source verification.
Spraying, spreading and lifting weight references use different installed systems; follow the DJI Agriculture app’s recommended load.
DJI manual v1.2 lists IP56 while v1.1 listed IP67. Inspect the exact hardware, seals and current documentation before planning wet-condition service.
Remove the battery, isolate chemical residue and obtain exact part numbers before any repair or compatibility claim.
