When it comes to agricultural drones, DJI continues to push the boundaries with advanced technology designed to improve efficiency and productivity in the field. The AGRAS T50 and AGRAS T40 are two of the most powerful spraying and spreading drones in DJI’s lineup, each offering cutting-edge features tailored for modern farming operations. But how do they compare?
In this article, we’ll take an in-depth look at the key differences between the T50 and T40 drones, including their spraying capacity, flight performance, technological advancements, and overall suitability for different agricultural applications. Whether you're looking to upgrade your current fleet or investing in your first agricultural drone, this comparison will help you determine which model best suits your needs. Let’s dive in!
The T50’s spray system is clearly an improvement over its predecessor. With a new solenoid valve, a larger pump and the option to add 2 extra nozzles, it boasts higher flow rates, less leakage and drift. Let’s take a look at the comparison table below:

Very small difference between the T40s and the T50s spreading systems. As such, very little difference should be seen in the field:

The T50's new obstacle avoidance radar has been a big leap compared to the T40s. With dual active phased array radars (front and rear), it detects objects flying at faster speeds and from longer distances, enabling high precision obstacle avoidance. It also carries a set of binocular vision sensors, capturing obstacles and sensing terrain, ensuring terrain following in 50° slopes (compared to 30° with the T40) and automatic obstacle bypassing. Overall, flying the DJI AGRAS T50 is a lot safer than flying its predecessor.
Mapping is almost 2x as fast with the T50 drone. Field mapping in 10 minutes covers:
The AGRAS T50 also has an option to map orchards at up to 20° slopes, reconstructing 3D routes, something that the T40 can’t do due to its lack of binocular vision sensors.
Propellers
Props are the same for both drones, though with the launch of the T50, DJI released a set of white propellers. While they are the same size as their black counterpart, they seem to weigh a bit more and we don’t recommend flying with white and black props on the same motor. Best to change all of them if possible and keep all of them the same color.
Size and Weight
Structurally, these drones are very much the same. In terms of weight and size, though, there are some minor differences. Let’s take a look at them:

Having been launched to take the T40's place, it’s no surprise that the T50 drone is the more expensive of the 2. Unfortunately, the manufacturer does not allow us to advertise its price online, so we encourage you to get a quote below to see pricing for yourself:
Now that we’ve talked about all that there is to know about the differences between the T40 and T50 drones, let’s take a quick look at what remains the same:
The DJI AGRAS T50 is a slight improvement over the T40. Overall, its added safety features ensure a safer operation, less prone to crashes and problems. It’s also a great fit for specialty use applications that require higher GPAs, like orchards and vineyards. We mostly recommend the T50 for anyone spraying today, whether they’re a newcomer or a veteran.
