Here is another drone that can spray your crops even in mountainous regions. The SMX X-F1 Crop Sprayer Drone has a max speed of 37.3 mph and can fly for 25 minutes. It has an all-weather design with a 3D auto-pilot system “PD-FC1” to perform reliably.
The drone flies over crops grown in steep slope regions and sprays with precision. The above video show it in action.
