Product overview
The DJI AGRAS T55 is an agricultural flight platform with folding arms and four pairs of 62-inch carbon-fiber composite propellers. Its standard spraying configuration combines two nozzles, a 50 L HDPE tank and a DB1050 battery, with a total aircraft weight of 45 kg including the battery. Deployment requires space for dimensions of 3190 × 3570 × 934 mm with arms and propellers unfolded. Folding both reduces the envelope to 1120 × 896 × 934 mm for transport and storage.
Spraying equipment offers a 50 kg working payload and maximum flow of 40 L/min with two nozzles or 50 L/min with four. Alternative working systems include the DS80L spreader, DS100L dual-auger vibration spreader and DL100 lifting system, with T55 payload ratings of 55 kg, 50 kg and 40 kg respectively. Payload ratings are measured at sea level; loading must remain within the recommended weight for current aircraft status, environment and task. Operation is limited to 0–40 °C and winds up to 6 m/s. The aircraft cannot actively avoid moving objects.

|
| Charger DC input voltage | DC 300–500 VCC15000 vehicle-mounted charger, model CCX901-15000. |
| D-RTK 3 positioning accuracy | PPP satellite service: 20 min convergence; horizontal 30 cm RMS; elevation 40 cm RMS. Network RTK calibration: horizontal 0.8 cm + 1 ppm RMS; vertical 1.5 cm + 1 ppm RMS. The 1 ppm term adds 1 mm per additional kilometer between aircraft and base station.D-RTK 3 Agriculture Edition; positioning accuracy and reliability depend on device tilt, signal obstruction, multipath, satellite count, satellite geometry and atmospheric conditions. Installation is recommended in an open area away from electromagnetic interference and multipath environments. |
