The DJI T40 and T50 are both large agricultural drones from the Agras line, built for spraying and spreading over cropland rather than for photography. The real question is how much capacity, battery handling and support your acreage calls for, and the maker’s specification pages settle the exact numbers. We have not used these products ourselves, so this guide sticks to stable, well-known traits.
What These Drones Are Built For
Both models sit in the heavy-lift class of farm drones. Their usual jobs are applying liquid crop products from a tank and, with a matching accessory, spreading granular material such as seed or fertilizer from a hopper. They are flown with a remote controller and a planning app, typically along mapped routes over defined fields.
Neither one is a camera drone. If your goal is aerial photos or video, a compact consumer or prosumer model is the right category instead.
Where the Two Models Differ
The T50 is generally positioned as the newer step in the line, and the T40 as the earlier one. Differences between generations tend to appear in a handful of areas, and each is worth checking on the maker’s page.
| Factor | What to check |
|---|---|
| Tank and hopper capacity | How much material each flight can carry, which affects the number of refills per field |
| Spray and spread system | Nozzle type, flow control and which spreading accessories are offered |
| Obstacle sensing | Which sensors are fitted and how they handle trees, poles and uneven ground |
| Battery and charging | Pack capacity, charging gear needed and cycle planning for a full day |
| Availability and support | Local dealers, spare parts and service options in your region |
Who Should Choose Which
- Choose the T50 if you work large or irregular fields and want the newer generation with the most recent features the maker offers.
- Choose the T40 if it fits your acreage and a dealer can supply it with parts and service nearby, especially when the newer model adds capability you would not use.
- Choose based on the support network in your area as much as on the spec sheet, since downtime during a busy season matters more than a small capacity gap.
How to Compare Them Properly
- Write down your typical field size, crop type and whether you spray, spread or both.
- Open the maker’s page for each model and note capacity, coverage rate and battery details side by side.
- Count how many battery packs and chargers each setup needs to keep working through a full day.
- Ask a local dealer about training, spare parts and turnaround time for repairs.
- Check the aviation rules that apply to agricultural drone work where you operate.
FAQ
Can the T40 or T50 be used for photography?
They carry sensors for navigation and obstacle sensing, but they are made for field work. For photos or video, choose a dedicated camera drone.
Is the newer model always the better fit?
Not always. A newer generation can offer more capability, but the better fit is the one that matches your acreage, your crops and the support available near you.
The Short Version
The T40 and T50 are both heavy-lift farm drones, with the T50 usually seen as the newer step. Compare capacity, spreading options, sensing, batteries and local support on the maker’s page, then choose the model that fits your fields and your service network.
