Using the T25

Getting Ready for Takeoff

1. Place the aircraft on open, flat ground with the rear of the aircraft facing toward you.
2. Make sure that the propellers are securely mounted, there are no foreign objects in or on the motors and propellers, the propeller blades and arms are unfolded, and the arm locks are firmly fastened.
3. Make sure that the spray tank and flight battery are firmly in place.
4. Power on the remote controller, make sure that the DJITM AGRASTM app is open, and then power on the aircraft. Go to the home screen in the app and tap Start to enter Operation View. Make sure that there is a strong signal (the GNSS icon or RTK icon on upper right corner of screen is white). Otherwise, the aircraft cannot take off.
   • RTK positioning is recommended. In the app, go to Operation View, tap and then RTK to select a method for receiving RTK signals.
   • DJI Cellular Dongle is recommended for internet connection. In the app, go to Operation View, tap and select Network Diagnostics. The cellular dongle and SIM card are functioning properly if the status of all the devices in the network chain are displayed in green.

Starting Operations

Users can perform mapping operations in the operating area using the DJI Agras app and receive an HD map via offline reconstruction using the remote controller, then plan a field on the HD map for Route operations. DJI Agras provides multiple methods to add points. The following description uses Route Mapping and Crosshair as an example.

• Only take off in open areas and set an appropriate Connection Routing and RTH Altitude according to the operating environment.
• An operation can be paused by moving the control stick slightly. The aircraft will hover and record the breakpoint. After which, the aircraft can be controlled manually. Select the operation again to continue. The aircraft will return to the breakpoint automatically and resume the operation. Pay attention to aircraft safety when returning to a breakpoint.
• In Route Operation mode, the aircraft is able to bypass obstacles, which is disabled by default and can be enabled in the app. If the function is enabled and the aircraft detects an obstacle, the aircraft will slow down and bypass the obstacle and return to the original flight path.
• Users can set the action the aircraft will perform after the operation is completed in the app.

Maintenance

Clean all parts of the aircraft and remote controller at the end of each day of spraying after the aircraft returns to a normal temperature. DO NOT clean the aircraft immediately after operations are completed.

1. Fill the spray tank with clean or soapy water and spray the water through the sprinklers until the tank is empty. Repeat this step three times.
2. Remove the spray tank strainer and sprinklers to clean them and clear any blockage. Afterwards, immerse them in clean water for 12 hours.
3. Make sure that the aircraft structure is completely connected so that it can be washed directly with water. It is recommended to use a spray washer filled with water to clean the aircraft body and wipe with a soft brush or wet cloth before removing water residue with a dry cloth.
4. If there is dust or pesticide liquid on the motors, propellers, or heat sinks, wipe them with a wet cloth before cleaning the remaining water residue with a dry cloth.
5. Wipe the surface and screen of the remote controller with a clean wet cloth that has been wrung out with water.

Refer to the disclaimer and safety guidelines for more information on product maintenance.

Fly Safe

It is important to understand some basic flight guidelines, both for your protection and for the safety of those around you.

1. Flying in Open Areas: pay attention to utility poles, power lines, and other obstacles. DO NOT fly near or above water, people, or animals.
2. Maintain Control at All Times: keep your hands on the remote controller and maintain control of the aircraft when it is in flight, even when using intelligent functions such as the Route and Fruit Tree modes and Smart Return to Home.
3. Maintain Line of Sight: maintain visual line of sight (VLOS) with your aircraft at all times and avoid flying behind buildings or other obstacles that may block your view.
4. Monitor Your Altitude : for the safety of manned aircraft and other air traffic, fly at an altitude lower than 100 m (328 ft) and in accordance with all local laws and regulations.

Visit https://fly-safe.dji.com for more information on critical safety features such as GEO zones.

Flying Considerations

1. DO NOT use the aircraft in adverse weather conditions such as snow, fog, winds exceeding 6 m/s, or heavy rain exceeding 25 mm (0.98 in) in 12 hours.
2. DO NOT fly more than 4.5 km (14,763 ft) above sea level.
3. The DJI Agras app will intelligently recommend the payload weight of the tank according to the current status and surroundings of the aircraft. When adding material to the tank, the max weight should not exceed the recommended value. Otherwise, the flight safety may be affected.
4. Make sure that there is a strong GNSS signal and the D-RTK antennas are unobstructed during operation.

Return to Home (RTH)
The aircraft will automatically return to the Home Point in the following situations:

• Smart RTH: The user presses and holds the RTH button.
• *Failsafe RTH :** the remote controller signal is lost.
• Low Battery RTH *: the aircraft battery level reaches the preset low battery threshold.

The aircraft decelerates and brakes and hovers if there is an obstacle within 20 m of the aircraft. The aircraft exits RTH and waits for further commands.

The action of the aircraft when the remote controller signal is lost or the aircraft battery level is low can be set in the app. Failsafe RTH and Low Battery RTH will only be available if RTH is set.
Obstacle avoidance is disabled in Attitude mode (which the aircraft enters in situations such as when the GNSS signal is weak) and is not available if the operating environment is not suitable for the radar modules or binocular vision system. Extra caution is required in such situations.

Pesticide Usage

1. Avoid the use of powder pesticide as much as possible and clean the spraying system after use. Otherwise, the service life of the spraying system may be reduced.
2. Pesticides are poisonous and pose serious risks to safety. Only use them in strict accordance with their specifications.
3. Use clean water to mix the pesticide and filter the mixed liquid before pouring into the spray tank to avoid blocking the strainer.
4. Effective use of pesticides depends on pesticide density, spray rate, spray distance, aircraft speed, wind speed, wind direction, temperature, and humidity. Consider all factors when using pesticides.
5. DO NOT compromise the safety of people, animals, or the environment during operation.

It is important to understand the basic flight guidelines, both for your protection and for the safety of those around you. Make sure to read the disclaimer and safety guidelines.

Aircraft

The Agras T25 features a truss-style body and pitched arms that can be folded to reduce the body size, making it easier to transport. The integrated spraying system can quickly transform into the spreading configuration.
The aircraft is equipped with the phased array radar system and binocular vision system, including downward and forward binocular vision and forward and rear phased array radars. The systems provide multidirectional obstacle sensing [1] as well as terrain follow and bypass functions to ensure flight safety. Boasting an ultra HD FPV camera with a tiltable gimbal, the aircraft can automatically collect HD field images for local offline reconstruction to assist in precise field planning. Using DJI SmartFarm platform and DJI MAVICTM 3M, prescription maps can be generated in order to perform variable rate fertilization.
The spraying system is equipped with the magnetic drive impeller pumps, dual atomized sprinklers, and brand-new solenoid valve, to improve spraying efficiency while saving liquid pesticide. The spraying system can be expanded with two more sprinklers to meet different operation scenarios. [2] Core modules adopt potting technology and the aircraft has a protection rating of IP67 (IEC 60529).
