Crop sprayers apply liquid fertilizers and pesticides over farmland during the growing period. Controlling the sprayer height is critical to this process. If the sprayer height is too high, the dispensed product may simply blow away in the wind. If too low, spray will not evenly distribute. Or worse yet, a low sprayer mechanism can collide with the crops or ground.
To ensure consistent, optimum spray coverage over uneven terrain and varying crop height, and to prevent the boom from impacting crops or soil, its height must be continuously monitored and adjusted.
