Horizontal boom sprayer calibration
This is the first of a series of short, educational and irreverent videos made with Real Agriculture to bring a little levity to sprayer education. Let’s face it – ironically, nozzles can be pretty dry. This first video discusses what a rate controller can be expected to do, and what it cannot do. Plus, we […]

Pulse-width Modulated flow control allows you to change travel speed by a factor of about five without a change in spray pressure. This chart shows which nozzle flow rates to use. Note the significant pressure drop across the Capstan solenoid. This value must be added to the cab spray pressure, as explained here. Capstan Tip […]

All sprayers experience a drop in pressure as the solution moves further away from the pump. Here’s why that’s important, and how to measure it. Optimal nozzle operation in terms of spray quality and fan angle is closely tied to spray pressure. As we try to maximize travel speed range with a modern sprayer, we […]
Undoubtedly, the number one question we get from operators is: “Which nozzle should I get”? Luckily there’s no simple answer, or we wouldn’t have jobs! The reason it’s not simple is because selecting the “right” nozzle for a sprayer is a process. It can be broken down into two steps: It’s a big question, so […]

It seems simple: The faster you drive the sprayer, the more area you cover. This makes higher travel speeds a seductive method for improving productivity. Sprayer manufacturers knew this 25 years ago when pull-type sprayers first received bigger, suspended outrigger wheels. Since then they’ve delivered more powerful engines, better hydraulic motors, smoother suspension and cruise […]
