LIMING WITH THE HYDROSEEDER
®
When using large concentrations of granular solids through the HydroSeeder
®
, it is advisable
to keep the slurry moving through the pump at all times. This keeps the solids from settling in the
lines, and creating a clog. This unit was designed for the application of agricultural-grade lime or
FINN-HLL liquid lime only.
PROCEDURE
1. With pump clutch disengaged (turned off) and agitator control in the
NEUTRAL
position,
start engine and allow it to warm up. See STARTING PROCEDURE.
2. After engine has warmed up, turn on the hydraulics system by flipping the hydraulics
toggle switch to the
HYDRAULICS ON
position (all the way up). The switch will
automatically center itself, which is the
ON
position.
3. Start filling the unit with water. When water reaches the top of the agitator shaft, move
agitator control to approximately 1/2 speed in REVERSE.
4. Open both the recirculation and discharge valves.
5. Remove discharge nozzle and gasket from discharge boom.
6. Aim discharge boom assembly into an open area away from any persons, obstructions, or
high voltage power lines.
7. Engage (turn on) pump clutch, and increase engine speed until you have reached
maximum engine speed. A stream of water should be coming from the end of the
recirculation pipe beside the hatch opening as well as from the boom.
8. As soon as both streams are clear, close discharge valve and make sure water is
being recirculated back to the tank.
9. Decrease throttle to 3/4 speed. Increase agitator speed to full REVERSE.
Do not disengage (turn off) clutch.
10. Twenty lb (9.02 kg) of granular solids displaces approximately 1 gal (3.8 L) of water.
When filling the tank with water, the volume of granular solids must be accounted for. For
example, if using the maximum recommended capacity of 5,000 lb (2,268 kg), 250 gal
(946 L) (5,000/20 = 250) would have to subtracted from the total tank capacity, thus 1,750
gal (6,624 L) - 250 gal (946 L) = 1,500 gal (5,678 L). If 1,000 lb (454 kg) of solids were
used, 50 gal (189 L) (1,000/20) would have to be subtracted, thus, 1,750 gal (6,624 L) -
50 gal (189 L) = 1,700 gal (6,435 L).
11. Fill the tank to the required capacity for the rate of granular solids to be applied.
12. Load the material (see LOADING section, steps 5 through 8).
13. When ready to apply slurry, install gasket and nozzle into boom.
14. Move agitator control to 3/4 speed, forward.
15. With the pump clutch still engaged (turned on), re-open discharge valve to commence
application.
To decrease pump wear and increase discharge distance, it may, at
this point be desirable to close the recirculation valve. However, the
recirculation valve must be open BEFORE closing the discharge valve if the application of
slurry is to be interrupted. Extreme heat, which will cause damage and/or bodily injury, will
occur if both valves are closed.
16. Apply the slurry. See APPLICATION OF SLURRY section.
17. If another load is to be applied, start again at step 1. If finished, follow the clean-up
procedure.
