About the DJI Agras T55
DJI Agras T55 is a multi-role agricultural drone for spraying, spreading, and lifting. DJI lists a 45 kg operating weight with the DB1050 battery or 48.4 kg with the DB1580 battery. Depending on battery and equipment, listed maximum takeoff weight reaches 108 kg for spreading, while the optional lifting system supports a 40 kg operating payload.

Common Failure Modes
Symptoms: Bent or cracked frame arm, loose arm sleeve, abnormal vibration, or visible crash damage.
Likely areas: frame arms, arm sleeves, landing gear, motor mounts
Agricultural airframes carry heavy loads — inspect arms and fasteners before every operation and after any hard landing.
Symptoms: Nozzle clog, uneven spray width, pump noise, flow-meter error, or tank leak.
Likely areas: nozzles/sprinklers, delivery pump, flow meter, tank seals, hoses
Flush the spraying system with clean water after each operation; never leave chemicals in the tank or lines.
Symptoms: Motor start failure, rough spin, propulsion warning, overheating, or unstable hover under load.
Likely areas: motor, ESC, arm wiring, power connectors
High-payload propulsion wears faster than consumer drones — follow the manual's inspection cycle (typically every 100 flight hours).
Symptoms: Terrain-follow instability, obstacle warnings, positioning drift, or RTK fix loss.
Likely areas: radar modules, RTK antennas, GNSS module, cabling
Clean radar and antenna surfaces of chemical residue and dust before calibrating or replacing hardware.
Repair Notes
Drain and flush the tank and lines before any service. Wear protective equipment — residue on the airframe is normal after operations.
Confirm the exact model, variant, error message and visible damage before selecting parts. Agras parts differ between generations even when they look similar.
Remove the flight battery before opening anything. High-capacity agricultural batteries store far more energy than consumer packs.
After replacing radar, RTK, propulsion or airframe parts, run the required calibration and a controlled low-altitude hover test WITHOUT payload first.
