But how do they compare with each other, and which one is more suitable for your needs? In this article, we will review the features, capabilities, and benefits of the DJI Agras T20 vs DJI Agras T40, and help you decide which one is the best choice for you.
What is a Drone Sprayer?
A drone sprayer is a type of unmanned aerial vehicle (UAV) that is equipped with a spray tank and a nozzle system. It can fly over crops and fields and spray liquids such as pesticides, herbicides, fungicides, fertilizers, and water. Drone sprayers are also known as agricultural drones, crop dusters, or crop sprayers.
Drone sprayers have many advantages over traditional methods of spraying, such as manual labor, tractors, or helicopters. Some of these advantages are:
- They can cover large areas faster and more efficiently, saving time and labor costs.
- They can spray more accurately and uniformly, reducing waste and environmental impact.
- They can access hard-to-reach areas, such as steep slopes, uneven terrains, or dense vegetation, where other methods cannot.
- They can operate in various weather conditions, such as wind, rain, or fog, where other methods may be unsafe or ineffective.
- They can collect and analyze data, such as crop health, soil moisture, and pest infestation, using sensors and cameras, and provide real-time feedback and guidance to farmers.
Drone sprayers are becoming more popular and widely used in the agricultural sector, especially in countries such as China, Japan, South Korea, and the United States
What are the main differences between the DJI Agras T20 vs DJI Agras T40?
The DJI Agras T20 vs DJI Agras T40 have many similarities, but they also have some key differences that make them suitable for different scenarios and applications. Here are some of the main differences between them:
1. DJI Agras T20 vs DJI Agras T40 Specifications
The DJI Agras T20 is a drone sprayer that was launched by DJI in November 2020. It is the successor of the DJI Agras MG-1P, which was released in 2018. The DJI Agras T20 is designed to be a versatile, powerful, and intelligent drone sprayer that can adapt to various crops, terrains, and environments.
The DJI Agras T40 is a drone sprayer that was launched by DJI in November 2021. It is the upgraded version of the DJI Agras T20, and it is designed to be a more powerful, efficient, and intelligent drone sprayer that can handle larger and more complex agricultural tasks. It has the following features and specifications:

2. Payload capacity
The DJI Agras T40 has a higher payload capacity than the DJI Agras T20. The T40 can carry a spray load of 40 kg (88 lbs) and a spread load of 50 kg (110 lbs), while the T20 can carry a spray load of 20 kg (44 lbs) and a spread load of 25 kg (55 lbs).
This means that the T40 can cover larger areas and spray or spread more materials in one flight, reducing the number of refills and flights needed. However, the T20 is lighter and more agile, making it more suitable for smaller or more complex terrains.
3. Propulsion system
The DJI Agras T40 has a unique coaxial twin rotor design, which gives it more power and stability than the DJI Agras T20. The T40 has eight rotors, arranged in four pairs of coaxial propellers, which generate more thrust and lift than the T20’s four rotors.
The T40 also has a more robust frame and landing gear, which can withstand more impact and vibration. The T20, on the other hand, has a conventional quadcopter design, which makes it more compact and foldable, and easier to transport and store.
4. Spraying system
The DJI Agras T40 has a dual atomized spraying system, which allows it to spray two different liquids simultaneously or switch between them quickly. The T40 has two separate liquid tanks, each with a capacity of 20 liters (5.3 gallons), and four nozzles, which can be adjusted to spray at different rates and angles.
The T40 can also spray ultra-low volume droplets, which can penetrate deeper into the crops and reduce drift and evaporation. The DJI Agras T20 has a single atomized spraying system, which can only spray one liquid at a time.
The T20 has one liquid tank, with a capacity of 20 liters (5.3 gallons), and four nozzles, which can also be adjusted to spray at different rates and angles. The T20 can spray low volume droplets, which can still achieve good coverage and efficiency.
5. Mapping and navigation
The DJI Agras T40 and the DJI Agras T20 both support RTK positioning, which provides centimeter-level accuracy for precise navigation and spraying. They also both have omnidirectional digital radar, which can detect obstacles in all directions and avoid collisions.
However, the DJI Agras T40 has some additional features that make it more advanced and versatile in mapping and navigation. The T40 has a binocular vision system, which can sense the terrain and crop height, and adjust the flight altitude and spraying angle accordingly.
The T40 also has an integrated DJI Terra software, which can create 3D maps of the fields, analyze crop health and growth, and generate optimal spraying or spreading plans. The DJI Agras T20 does not have these features, and relies on external devices and software for mapping and planning.
Which one should you choose: the DJI Agras T20 or the DJI Agras T40?
The DJI Agras T20 vs DJI Agras T40 are both excellent agricultural drones that can help you with your spraying or spreading needs. However, depending on your specific situation and preferences, you might find one more suitable than the other. Here are some factors to consider when choosing between them:
- Budget: The DJI Agras T40 is more expensive than the DJI Agras T20, due to its higher payload capacity, dual spraying system, and advanced mapping and navigation features.
