Agras T25/                   32              22
Agras T30                    23              15

Will my drone stop if it gets too close to an obstacle?

Yes, the omnidirectional radar on each Agras model supports industry leading obstacle detection and avoidance. The radars can detect obstacles such as trees, powerlines, and pivots to ensure safe operations.

Do spray drones have a camera?

Yes, all Agras models come with FPV cameras for operator awareness.

Can I adjust my droplet size?

Yes, each Agras drone comes with the ability to change droplet sizes based on your spray application. The Agras T50/T40/T25/T20P utilize rotary nozzles that can be adjusted on the fly in the Agras App. The Agras T30 Utilizes traditional fan nozzles that can be easily switched to create a larger or smaller droplet.

Can I wash my drone after spraying?

Yes, you can rinse your drone off after spraying. Although the Agras drones are waterproof, we recommend using a wet cloth around sensitive parts such as the motors and power distribution connection. *NO PRESSURE WASHER

What is the life expectancy of a spray drone?

The longevity of your drone depends on how well you maintain your equipment. A well-maintained drone can support thousands of acres.

How long does it take to get parts?

We know when it’s time to spray there is no room for downtime. We stock a full inventory of spray drone parts to ensure downtime is kept to a minimum for all our clients. Parts can be shipped within 24hrs.

Efficiency

What is the hourly spraying efficiency for Agras drones?

Please refer to our product pages for the efficiency of each Agras model in different scenarios. Note that the data are estimates, and actual results may differ.

What are the optimal swath settings for spraying?

Please refer to our product pages for our recommended swath of each Agras model.

Will my swath decrease if I fly slower?

Yes, the swath from each Agras model is generated by the altitude and speed of the drone. Pattern testing may be required for applications that require low speeds and high volume.

Can I spread granular fertilizer with my drone?

Usually, fertilizer requires a high lb/ac rate which makes applying with a drone highly inefficient. The best applications for the spreading system are products that require 50lbs or less per acre.

Can I calibrate the spray system on my drone?

Yes, both the spraying system and the spreading system can be calibrated as needed.

Can I operate multiple drones(swarm) off one controller?

Yes, there is an approved exemption you can obtain for over 55lb swarming. If you would like to run multiple drones, we still recommend a controller and pilot assigned to each drone.

How high of wind can I spray in with a drone?

Please refer to the Label of the product you are spraying for wind restrictions. Most labels require a wind less than 10mph, which will reduce drift potential and ensure even coverage.

Battery/Flight times

Battery/Flight times

How many acres can I spray in a single flight?

Acres per flight will be determined by the capacity of the drone and the GPA.

Below is a chart based off 2GPA

    Model                     GPA         Acres
Agras T40/T50            2              5

Agras T30                     2              4

How long does it take for a drone battery to charge?

On average, all Agras batteries take 9-12min to charge from 20%

What is the life expectancy of an intelligent flight battery?

The life expectancy of an Intelligent flight battery is between 1200-1500 charge cycles (20-100%) depending on which Agras Model you have.

How long can my spray drone fly?

The life expectancy of an Intelligent flight battery is between 1200-1500 charge cycles (20-100%) depending on which Agras Model you have.

Please refer to the chart below for loaded and empty flight times.

Agras T50/T40

loaded: 7 min 30 sec
No payload: 18 min 30 sec

Agras T25

Fully loaded: 13 min 27 sec
No payload: 28 min 58 sec

Agras T30

Fully loaded: 7 min 48 sec
No payload: 20 min 30sec

Note: The actual flight time is subject to factors such as the operating environment and the number of battery cycles. The above test results are for reference only. The flight time of the T40 and T20P is shorter when they are used with their spreading systems. No test results are available. We recommend that you refer to the test results with spraying systems.

What happens if my drone runs out of battery while in the air?

All Agras models come with a safety feature which will land the drone if the flight battery becomes too low. However, the Agras Software supports battery management functions that
alert you when your flight battery is running low to avoid auto-landings.

How many batteries do I need to operate continuously?

All our spray drone bundles come with three batteries which allows for continuous flight and all-day operations. In some cases, a fourth battery may be required if your refill times are less than 45 seconds.

Support Trailers/Generators

Trailers/Generators

How many gallons of water should I carry on my drone trailer?

In most cases, 500-750 gallons of fresh water will be sufficient to support a single drone for a day of operations.

How big of a batch tank do I need to mix my chemicals?

A cone-bottom tank ranging from 60 to 100 gallons, equipped with a large lid and agitation capabilities is best for drone spraying operations. This setup ensures thorough mixing of chemicals before transferring to the drone tank. Each batch will cover 30 to 50 acres at a rate of
two gallons per acre. For multiple drone operations, opting for a larger batch tank can help increase efficiency.

What size generator do I need to fast charge batteries?

We recommend using a generator with a 12,500 running watt capacity on all Agras Models. This will allow for fast charging, and running accessories such as pumps, lights, and fans.
Please note that the generator you select will need a total harmonic distortion (THD) rating of <5%. Below are a few of our brand recommendations.

  • Honda (NorthStar)
  • Westinghouse
  • Kubota (Diesel)
Do I have to have a landing platform on the top of my trailer?

Your trailer design will need to be built around your application. If you are spraying crops with a high canopy – a platform could be useful for maintaining line of sight and RC connection. For other applications such as pasture spraying – the added height of your trailer could make it difficult to get into some fields. Landing on the ground will always be the safest option when practical.

Q: How long of a transfer hose should I use, and what type of nozzle?

A 50ft hose reel is recommended. Fuel nozzles or ball valves have proven to be a fan favorite for filling drone tanks. Either a ¾” or 1” line can be used depending on how fast you want to fill the drone tank.
