The DJI Agras T40 is an agricultural drone built for spraying and spreading at scale: a 40kg (10.5-gallon) spray payload, a 50kg (18.5-gallon) capacity in spreader configuration for granular material, and RTK-guided coverage of up to 52 acres per hour. DJI doesn’t publish a fixed retail price. It’s sold through agricultural drone dealers on a quote basis, typical for equipment at this scale.
What is the DJI Agras T40 actually built to do?
The T40 is a purpose-built farm tool, not a repurposed photography drone. Its coaxial twin-rotor design carries either a liquid spray payload or a dry granular spreader payload. That lets the same airframe handle pesticide and fertilizer spraying as well as seed or granular fertilizer spreading, depending on which module is attached.
What are the key specs?
- Spray capacity: 40 kg (roughly 10.5 gallons), with an estimated 30-foot spray swath and about 3 gallons per minute output
- Spreader capacity: 50 kg (18.5 gallons), holding up to roughly 115 lbs of granular material
- Coverage rate: up to 52 acres per hour under RTK-guided precision flight
- Spray system: dual atomized centrifugal nozzles designed to keep droplet size uniform and reduce clogging with powder-based chemicals
- Sensing: active phased-array radar and binocular vision for terrain-following and obstacle avoidance over uneven fields
- Camera: 12-megapixel gimbal FPV camera for real-time monitoring during a pass
How does it compare to spraying by hand or tractor?
The 52-acre-per-hour coverage rate is the headline number. It’s the reason operations at real scale have moved toward drone spraying: a T40 covers ground a backpack sprayer can’t touch in a day, without the soil compaction a ground vehicle causes crossing wet or uneven fields repeatedly. RTK precision guidance also cuts down on overlap and skipped strips compared to manual passes. That directly affects chemical cost, not just labor time.
What does it cost, and how do you actually buy one?
DJI doesn’t list a fixed price for the Agras T40 on its own site. It’s sold through a network of agricultural drone dealers, most of whom list it as “contact for price” or quote-on-request. That’s standard for equipment at this scale, where price often bundles in training, service support, and sometimes financing. Expect cost to vary meaningfully by dealer and region. Getting a direct quote is the only reliable way to know current pricing.
