Applying the Hydroseed
Connect as many hoses to your machine as you need, dragging them out as you connect
each section. Finally, connect the gun to the hose. Make sure the gun valve is closed
before opening the hose valve on the hydroseeder. Keep the engine running at maximum
rpm to provide the best performance at the gun.
Begin to close the agitation valve. The further closed the valve, the more pressure will be
present at the gun. (See picture BELOW) In some situations, you may want to have the
agitation valve closed completely to achieve the maximum spray distance and flow from
the gun. Remember that the agitation acts as your bypass for the pump to prevent the
seals from burning out. If you run the machine with the valve closed, be mindful that you
will need to get back to open the agitation valve if you will not have any flow through the
gun for more than 30 seconds. It is best to keep the agitation opened slightly to have
constant bypass.
When spraying, work your way back and forth evenly covering the ground with mulch.
Every 100 gallons of product should cover roughly 1,000-1,200 square feet. In dry
conditions, you may find you can only cover ¾ of that amount. Use the valve on the gun
to control the flow to prevent splattering sidewalks and siding. If additional hoses are
installed, drop the hose sections as you go. This will reduce fatigue for the operator and
make moving across the area much easier. Simply drag the hose to the side.
When disconnecting hose sections, turn the valve off at the gun. Walk to the machine
and close the hose valve. Make sure to open the gun valve to relieve the built-up
pressure that is in the hose. Connect the gun to the next hose, open the hose valve, and
begin spraying again. Occasionally open the agitation system on the hydroseeder to
ensure the mulch and seed are evenly mixed. Spray until the tank is empty and repeat!
