Why are 3-point PTO driven sprayers so expensive?

I just don't see why it costs so much for a blown plastic container, a small PTO driven pump, a cheap steel frame and boom, and some hoses and nozzles. I've had a FIMCO 55 gallon sprayer with a 10ft boom for around 10 years and would like something bigger to run behind the M6060. This 200 gallon model with a 20ft boom is $3,500 and there are much more expensive models out there.


This Ag Spray 165 gallon sprayer with a 28ft boom has a sale price of $6,800! It looks like a good sprayer but the cost is nuts. It seems to me that 3-point PTO driven sprayers provide a huge profit margin for the manufacturer but I could be wrong about that.

Because they are made in low volume.

Have you looked into changing the spray nozzle tips to a different type? For instance, TeeJet has data charts on all their nozzles regarding spray pattern, gpm output at certain pressures, etc. You may need to modify your boom by changing the number of nozzles to get the same coverage with much less water gpm output. Or build a separate boom with that nozzle design.

It looks like you'd need a nozzle/spacing combo that would put out about 4.5 gallons per acre at the speed you'd like to drive. Finding the right size/type of nozzle tip and spacing to do that should b possible using those charts.... and either regulating the pressure or using a bypass valve on the tank.

But it’s a tradeoff in that the less gpm output for your needs (less speed, less water, same coverage) could likely be met with a much finer droplet size or even a mist for the same amount of coverage. Then you would have to start worrying about temperature inversion spray drift, any wind above dead calm conditions, etc. You have to design for a happy compromise using speed/nozzles/pressure to fit your needs & conditions.

When we were raising 3 acres of sweet corn to sell, I had 3 booms made up with different nozzles/tips/spacings. One for lawn care, one for full coverage herbicide in the sweetcorn patch, and one for 8” band spraying the individual corn rows with some very expensive herbicide that would kill the grass in the sweetcorn rows.

How about a flock of sheep or goats, they do a heck of a job cleaning stuff up, or did I miss something?

Exactly!! And possibly a lower boom height.
