SMALL MOTORIZED SPRAYERS
Some small sprayers have all the components of larger field sprayers but
are usually not self-propelled. They may be mounted on wheels so they can
be pulled manually, mounted on a small trailer for pulling behind a small trac-
tor, or skid-mounted for carrying on a small truck. They may be low-pressure
or high-pressure, according to the pump and other components with which
they are equipped.
Standard equipment includes a hose and an adjustable nozzle on a handgun.
Some models have multi-nozzle booms. These sprayers are suitable for rela-
tively small outdoor areas, especially small orchards, ornamental and nursery
plantings, and golf course greens.
Advantages:
•
larger capacity than hand sprayers
•
low- and high-pressure capability
•
built-in hydraulic agitation
