We bought one last winter and have sprayed about 1000 acres so far with it. Have used it on about 100 acres spreading cover crop seed as well.
Quite a steep learning curve, but not impossible by any means. There are some quirks, lots of safety features that can be detrimental to use-ability, but has kept us from smoking trees at high speed inadvertently.
We bought the same kit as mentioned above minus the generator. Purchased a Miller Bobcat welder/generator instead. It keeps up most of the time but is slightly undersized.
If in good flying conditions (long passes, smooth topography), the batteries will spray out an entire tank with power to spare. If doing a field with a lot of short runs, the battery will burn off quicker than the tank can be sprayed. The skill is figuring out how to properly load the sprayer to be the most efficient for the field conditions. If the battery will only last for 8 gallons, no need to fill to 10 or 11…that’s carrying around more weight for no gain.
From my experience, if a ground rig can travel without undue damage to the crop or the field, it will do a better, more even job of applying the product. Booms are less susceptible to wind than a drone. However, the drone has its place and can be leveraged to avoid hiring expensive planes who show up too early or too late for crop conditions.
Very useful tool in certain conditions where other tools can’t perform. Will NOT completely replace a ground rig sprayer…in my opinion.
