Product Manual

the most commonly used
nozzle. The wide flat
nozzle that comes with
your system will have
the number 80400, or 80580
stamped on it. There is a
nozzle which will put
out a straight stream.
This is a distance nozzle.
It is used to obtain
maximum reach. It is a
little more difficult to
obtain a good even
application. With a
little practice you can
achieve maximum
distance and an
acceptable application.
The 25200 nozzle has a
narrower pattern, and a
lower application rate.
It is primarily used for
trimming, some people
like it for intermediate
distances. Units
equipped with the 1 ½”
hose option also come
with a 50800 nozzle. This
makes an excellent
medium distance nozzle,
and is ideal for tacking
straw as well.
*TIP Hydro Seeding
mulch often contains
some foreign material. If
you are spraying and you
notice your spray
pattern suddenly
change (usually from a
flat spray to a V
pattern), you have
something stuck in your
nozzle. Close the gun
valve, unscrew the
nozzle, and tap out the
obstruction. Should you
continue to spray with
the obstruction in the
nozzle, you may find
that the obstruction
will filter out the
mulch and you can end up
with a plug in the hose.
SPRAY TECHNIQUES
The gun may be held in a
horizontal position or
pointed down in a
vertical position. Many
people like to hang the
hose over their shoulder
which will leave one
hand free to move the
trailing hose out of the
way.
Spraying the gun down
will give maximum soil
penetration. Spraying
the gun out and letting
the material fall gently
onto the surface will
build up the heaviest
application of
protective mulch.
Some people like to use a
combination technique.
Walking a pattern and
spraying down to get
good seed penetration
and good seed to soil
contact, then pausing
occasionally to lift the
gun, gently over
spraying the area they
have already done to
build up a thicker mulch.
Some people adjust their
pattern to the soil
conditions. In very light
fluffy soil conditions
spraying out to build up
a mulch cover, and on
firm soil spraying down
to penetrate the
surface.
There are many
techniques used in hydro
seeding. Experiment to
find the one that you
like and the one that
works for you.
