DJI’s Agras T40 is a high‑capacity agricultural drone built around a coaxial twin‑rotor design that supports both precision spraying and granular spreading in a single platform. It combines a 40 L liquid operation box (40 kg operating payload) with a 70 L spreading tank (50 kg internal load), dual‑atomized centrifugal sprinklers for uniform droplet control, and an advanced sensing suite (Active Phased Array Radar plus Binocular Vision) for 360° obstacle awareness and terrain following. Core modules carry an IPX6K protection rating for harsh‑environment durability, while O3 Pro transmission with RTK delivers centimeter‑level positioning for repeatable, data‑driven operations. A dedicated high‑output generator enables rapid battery turnarounds to keep acreage rates high.

Advantages

  • High throughput for spraying and spreading in one aircraft (40 L spray, 70 L/50 kg spread) to reduce mission swaps and increase productivity.
  • Dual‑atomized sprinklers produce uniform droplets with a wide 50–500 μm range to match crop, chemical, and drift‑control needs.
  • Omnidirectional radar plus binocular vision provide 360° awareness, terrain following up to 30° slopes, and enhanced safety around obstacles.
  • RTK positioning and O3 Pro link support precise, repeatable application paths and robust command/video range for large fields.
  • Ruggedized design with IPX6K‑rated core modules and magnetic‑drive pump that isolates chemicals for durability.
  • Fast battery turnarounds (about 9–12 minutes per pack with the dedicated generator) sustain high acreage rates during peak season.
  • Integrated DJI Terra/RC mapping workflow enables surveying, prescription generation, and execution within the same ecosystem.

Disadvantages

  • Short endurance at maximum payload (approximately 6–7 minutes per sortie), requiring careful mission planning and multiple batteries.
  • Large size and mass (up to 90–101 kg TOW) demand ample staging space and trained crews for safe operations.
  • Modest wind tolerance (about 6 m/s) can limit spraying windows in breezy conditions.
  • Availability varies by region and channel; many purchases are via authorized dealers rather than direct DJI online sales.
  • Total system cost can be significant once batteries, charger/generator, and spreading kit are included.
