The sprayer industry needs a reset. Take a drive-train & boom, remove all plumbing. Bring in some fresh engineers & task with plumbing design to minimize rubber hose length and valves, maximize stainless, & minimize remaining volume. Waste free prime, easy clean, fast fill. Go!

To check the distribution of a fertilizer spread,
@Amazone
developed the
#EasyCheck
system. A rubber mat captures the pills and their distribution is photographed via the app. Images are then analyzed and the transverse distribution is shown. No pans, no weighing.

Imagine a sprayer filter housing that you can inspect w/o opening it. And can open w/o a tool. And can vent and pump dry before opening to avoid mess. And has the surface area for a reasonable service interval. Simple improvements that should be called ... Productivity tools.

and
@Agrifac
have the largest tanks and Agrifac has the widest booms. They're not the heaviest, though. And they are also the most well designed and sophisticated machines on the market.

As a rule, choose the coarsest spray quality that still provides adequate coverage and efficacy. Do this to slow droplet evaporation and minimize spray drift.
Here's a handy table to guide your decisions for major mode of action groups.

It's tempting to use fine sprays and low water volumes to improve sprayer productivity.
But don't do it.
It's not good for Ag.

And don't spray onto dew.

If you're new to the sprayer world, here is a cheat sheet for the ISO colour coding of nozzles. You can even use it to ballpark a nozzle selection or application rate if you don't have a proper chart. We've based it at speeds of 10 for easier conversion.

This is Florian Thiess, my Grade 4 teacher, & me in February 1975. I had told him we were moving to Canada & he said, I know some English, I can teach you. So we spent one hour after school each afternoon for 5 days going over the basics. Took this pic on the last day. Gratitude.
