HYDROSEEDER®SAFETY SUMMARY SECTION
It is important that all operators of this machine are familiar with all of the safety aspects mentioned below and
have read the entire Operator’s Manual before operating the machine. Always keep a copy of this manual
with the machine. It is the responsibility of the operator of the machine to fully understand this safety sheet.
Remember that YOU are the key to safety. Good safety practices protect not only you but also the people work-
ing with and around you. Keep in mind that this safety sheet is written for this type of machine only. Practice
all other usual and customary safe working precautions; and above all, remember that safety is up to you.
The FINN HydroSeeder®is designed to mix and apply water, seed, fertilizer, agricultural lime and hydraulic
mulch to the prepared seedbed. The resultant slurry from mixing one or more of the above materials may react
causing harmful or deadly gasses within the tank. Heat, evaporation or extended emptying period can/will
accelerate the formation of these gasses. Please contact your supplier(s) of these slurry components regarding
their potential reactivity.
I. PRE-START EQUIPMENT CHECK (equipment
check is to be made with the engine off):
1. This machine is equipped with two lifting devices; fork-
lift channels and a lift ring. Do NOT lift unit with any
water or material in it. The lifting devices are designed
to carry only the empty weight of the machine approxi-
mately 1050 lbs. (476 kg).
2. Check devices securing HydroSeeder®to the truck or
trailer frame.
3. If the HydroSeeder® is
mounted to a trailer, check
hitch and hitch bolts, safety
chains, lights, brakes and
breakaway switch. Verify
that the hitch ball is the cor-
rect size for the coupler.
4. Verify that all guards are in
place.
5. By carefully looking down
through the loading hatch,
inspect the slurry tank for
foreign objects. Never
enter the tank without fol-
lowing the procedures
described in #3 of the
Maintenance section in
this sheet.
6. Make sure no one is working on or inside the machine.
Signal “All Clear” before starting the engine.
7. Inspect all hydraulic hoses for cracks, bulges or dam-
age. If hoses are bad replace immediately.
8. Inspect all discharge hoses for cracks, bulges or dam-
age. If hoses are bad replace immediately.
II. MACHINE OPERATION:
1. Always wear safety goggles
when operating the machine.
Other safety attire such as
safety shoes, ear protec-
tion, gloves, hard hats, dust
masks, etc. should be worn
as required by warning decals
on machine, operator’s man-
uals or job site requirements.
Remove rings, watches, etc. Avoid loose fitting cloth-
ing that may get caught in rotating machinery.
2. Do not operate the machine
without all guards in place.
3. Do not load unit while in tran-
sit. Load only when parked
and unit is as level as pos-
sible. Take care not to drop
pens, lighters, etc. or pieces
of paper or plastic bags into
the tank, as these objects
might plug the slurry sys-
tem. Should any object be
dropped into the tank, do
NOT reach into the tank to retrieve the foreign object.
See #3 under Maintenance before allowing any per-
sonnel to enter the tank.
4. Make sure area to be sprayed is clear of all persons,
animals, etc.

3
5. The T-30 HydroSeeder® is a non-platform machine.
The discharge operator is positioned at the end of the
discharge hose; not on the towing or carrying vehicle.
6. Never operate machine in
an enclosed area without
venting the engine exhaust
of both the equipment and
vehicle on which the equip-
ment is mounted. Deadly
carbon monoxide fumes can
accumulate.
7. Never operate this or any other machinery when
fatigued, tired, under the influence of alcohol, illegal
drugs or medication. You must be in good physical
condition and mentally alert to operate this machine.
8. Never modify the machine. Never remove any part
of the machine (except for service and then reinstall
before operating).
III. SLURRY APPLICATION:
1. Do not aim discharge spray
toward power-lines, trans-
formers, or other high voltage
electrical conductors. Also
do not aim discharge spray
towards people, animals
or anything other than the
intended application area.
2. Never engage the clutch
when both the recirculation
and discharge valves are
closed. Operation with both
valves closed will result in
extreme heat generation that
could cause severe bodily
injury and damage to the
equipment.
3. Recirculation valve must be open and material flow-
ing back into the tank when using the remote valve. A
closed or plugged recirculation line will cause extreme
heat in the pump or discharge lines which will result in
severe bodily injury and damage to the equipment.
4. During application through a hose, high pressure
can be exerted at the end of the hose. Hose holding
personnel must establish good footing. The operator
should apply gradual pressure to the hose only after
hose holding personnel are firmly positioned and have
firm control of the hose. Additional personnel to direct
hose may be necessary if working on slopes. The
proper technique for hose holding personnel is to firmly
grasp the hose over the shoulder or under both arms.
Never hold the hose so it goes between the legs. If the
hose holding personnel finds that it is uncomfortable
for him to handle the hose by himself additional hose
holders should be positioned at the end of the hose.
5. Plan application so that the furthest area is covered
first; working back toward the HydroSeeder®, so that
the individuals are not walking back over slippery
ground.
6. Before opening any valves or pipe clamps shut
machine down and check if material in the pipe is hot.
If hot, do NOT open valve or pipe clamps as the hot
material may cause severe personal injury. Allow to
cool and open with caution.
7. Except when loading materi-
als keep loading hatch lid
closed to protect operator
and prevent splashing of wet
material onto the tank top.
8. Wash off spillage of slippery mulch or slurry additive
from the tank top and platform before operating equip-
ment.
IV. MAINTENANCE:
1. Before servicing the machine,
turn off engine and allow all
moving parts to stop. To pre-
vent accidental starting dis-
connect battery cables. Tag
the engine operating area
to show that the machine is
being serviced. Use lockout/
tagout procedure (OSHA 29
CFR 1910.147).
2. Certain hydroseeding amendments, when combined
with or without the addition of water or heat or the
element of time, may react causing harmful or deadly
gasses! Consult your material suppliers regarding
reactivity information. The slurry tank must be flushed
and drained after each day of operation.
3. Your slurry tank may be con-
sidered a confined space
by OSHA under 29 CFR
1910.146. Before entering
any confined space, your
company must develop a
procedure for safe entry.
Make sure your company’s
plan meets all the require-
ments of 29 CFR 1910.146. Including the following:
a) Drain, flush and ventilate tank interior.
b) Turn off engine and disconnect battery cables
and perform lockout/tagout procedures. (29 CFR
1910.147)
c) Provide continuous ventilation or proper breathing
apparatus.

4
d) If tank must be entered, personnel entering the
tank must be tethered to a lifeline.
e) Provide stand-by individual outside of tank able to
communicate with person inside and able to haul
him out with lifeline if necessary.
4. Before loosening any clamps
or opening any valves, deter-
mine if material in the line is
hot by feeling the pipe. Do
NOT allow material to come
in contact with personnel.
Severe bodily injury could
result.
5. On trailer units perform general maintenance such as
checking the safety chains, hitch and hitch bolts, tires,
brakes. Repair or replace if worn or broken. Never
operate machine on improperly inflated or damaged
tires. Always use a safety cage or cable restraints when
re-inflating a repaired tire.
6. Battery maintenance: Lead-acid batteries contain sulfu-
ric acid, which damage eyes of skin on contact. Always
wear a face shield to avoid acid in the eyes. If acid
contacts the eyes, flush immediately with clean water
and get medical attention. Wear rubber gloves and
protective clothing to keep acid off skin. Lead acid bat-
teries produce flammable and explosive gasses. Keep
arcs, sparks, flames and lighted tobacco away.
7. Filling of fuel: Never fill the tank with the engine run-
ning, while smoking or when near an open flame. Never
smoke while handling fuel or working on the fuel sys-
tem. The fumes in an empty container are explosive.
Never cut or weld on fuel lines, tanks or containers.
Move at least 10 feet (3 meters) away from fueling point
before starting engine. Wipe off any spilled fuel and let
dry before starting engine.
NOTE: Be careful not to allow fuel, lubricant, hydrau-
lic fluid or cooling fluids to penetrate into the
ground or be discharged into the water system.
Collect all fluids and dispose of them properly.
8. It is recommended that only authorized genuine FINN
replacement parts be used on the machine.
9. Diesel fuel or hydraulic fluid under pressure can pen-
etrate the skin or eyes and cause injury, blindness or
death. Pressure may build up in the hydraulic system;
use caution when removing the cap.
10. Make certain that all decals on the machine are main-
tained in good legible condition. Replacement decals
are available through Finn Corporation by specifying
part number shown in the lower right hand corner of
the decal. See page 5 for the current safety decals
mounted on the unit. See pages 50-51 in the Parts
Manual for the location and quantity of all decals on this
unit.

OPERATION AND MAINTENANCE
MANUAL FOR THE
FINN T30 HYDROSEEDER®
This manual gives you step by step instructions for the operation and maintenance of the Finn HydroSeeder®.
For best results and to insure longer life of the equipment, please follow the instructions carefully. For your
safety read the entire manual before operation of this unit.
DEFINITION OF HYDROSEEDING:
Hydroseeding is the process whereby seed, fertilizer and/or lime and fiber mulch (using water as a carrying
medium) are applied on the soil to establish vegetation.
THE FINN HYDROSEEDER®AND HOW IT WORKS:
The Finn HydroSeeder®will apply seed, fertilizer and/or lime, fiber mulch, or stabilizing materials in any pre-
scribed or desired combination. The materials placed in the HydroSeeder®slurry-tank are mixed with water
and kept in suspension by a dual agitation process, recirculation of slurry and mechanical agitation, thus form-
ing a slurry that is pumped to the discharge assembly and directed onto the seed bed by the operator. This equip-
ment is designed to accomplish hydroseeding in one easy operation with maximum efficiency.
TOWING VEHICLE
The trailer mounted HydroSeeder®, is to be mounted onto a truck or trailer which can carry a payload of at least
4,540 lbs. (2,068 kg.). This is the weight of the fully loaded HydroSeeder®. Any auxiliary loads due to material
storage or optional equipment, as well as the weight of the carrier vehicle, must be added to obtain the proper
carrier vehicle capacity.
Once the proper carrier has been selected, the HydroSeeder® must be securely mounted to it.
CAUTION: Your FINN HydroSeeder® should be mounted by a qualified truck
body installer.

When mounting the HydroSeeder®to the truck, any one of the following methods of mounting is acceptable:
A. Bolt the HydroSeeder®directly to the truck bed. Installer must insure that the bed to truck and
HydroSeeder® to bed connections are adequate for the full load weights that are shown on page 6.
B. Mount the HydroSeeder®to the truck frame. The T30 HydroSeeder®is provided with an adapter frame
which also allows the unit to be mounted directly to the truck’s 34” wide frame using U-Bolts.
IMPORTANT: Mounting the HydroSeeder®to the truck must allow for tire clearance
as well as frame twist. Place hard wood spacers along the length of
truck rails or use Finn spring mounting kit (#011562) or equivalent.
IMPORTANT: When using a truck with a tilt bed be sure to chain the truck bed down
to prevent the bed from being accidentally hoisted.
WARNING: This machine is equipped with two lifting devices: forklift chan-
nels and a lift ring. Do NOT lift unit with any water or material in
it. The lifting devices are designed to carry only the empty weight
of the machine, approximately 1,500 pounds (680 kg).
ATTACHMENTS (OPTIONAL):
1. Discharge hoses: Discharge hoses are available in 50 ft. (15 m) and 100 ft. (30 m) lengths up to a
total of 150 ft. (45 m). Hose of a greater length may adversely affect the discharge distance, and the
discharge time of the HydroSeeder®. All connections are camlock quick operating fittings, including
the connection to the end of the discharge piping. A nozzle is connected to the end of the hose next to
the remote discharge valve. Once the hose is connected, the HydroSeeder® is ready to operate. Flow
through the hose and the nozzle is controlled by the remote discharge valve. When using this valve, the
recirculation valve on the HydroSeeder® MUST BE OPEN to allow flow at times when the remote
valve is closed. See Figure 2 on page 9.
DANGER: The recirculation valve must be open when using a remote valve.
If valve is not open, extreme heat will occur resulting in damage
and/or bodily injury.
2. Air Gap Fill Pipe: A bolt on the air gap fill pipe is available that mounts directly to the raised hatch liner
and swings into position when the hatch lid is open.

PRE-START CHECK:
Safety check to insure operator safety:
1. A. Skid Unit - Check condition of all mounting hardware securing HydroSeeder® to truck bed and
frame rails.
B. Trailer Unit - Inspect hitch, safety chains, lights, brakes and breakaway switch.
2. Insure that all guards are in place.
EQUIPMENT CHECK:
CAUTION: Equipment check is made with the engine off and all rotating parts
stopped.
1. See that tool kit contains all the prescribed items (see tool kit list on page 55).
2. Inspect the “slurry-tank” for foreign objects. See numbers 2 and 3 in Maintenance Section (IV) of the
Safety Summary Section page 3.
3. Check fuel level.
4. Check the hydraulic oil level (see hydraulic system for oil specifications).
5. Check engine oil level . . . for oil type refer to the engine manual.
6. Inspect air cleaner for dust and dirt, clean if necessary.
7. Secure the tank drain plug in the drain pipe located in the center of the bumper.
8. Check to be certain pump drain plug is in place.
9. Lubricate equipment - See Lube Chart on page 18.
A. Each lubrication point is marked.
B. Check automatic pressure lubricator at pump. If the stem is fully extended with thumb nut all the way
up, the pressure lubricator contains lubricant - if not, lubricant must be replaced by the following
procedure:
a) Turn thumb nut clockwise until stem rises to maximum height.
b) Remove cap and fill cap with sodium (water soluble) base grease. (FINN part number 000698).
Do not use lithium base (chassis lube) grease.
c) Replace cap.
d) Turn thumb nut counter-clockwise until the thumb nut is at the top of the stem. The spring and
pressure disc in the lubricator forces the grease, under pressure, to the pump seal.
IMPORTANT: When the thumb nut has moved down
to within ½” (1.25 cm) of touching the
cap, reservice the automatic lubricator.
10. Check and clean the nozzles and hoses of any obstructions.
11. Check pump discharge, recirculation, and remote valve handles for
free movement.

VALVE OPERATION:
The base HydroSeeder®is equipped with three (3) independently operated ball valves to control slurry flow (see
Fig. 2). The first valve is the recirculation valve. An open recirculation valve allows flow back into the tank.
The second valve is the pump discharge valve. An open pump discharge valve allows slurry to flow through the
discharge hose. The third valve, located at the end of the discharge hose is the remote valve. An open remote
valve allows discharge of the slurry onto the area being covered.
WARNING: Never engage (turn on) the slurry pump clutch when the recir-
culation valve and either the pump discharge or remote valve is
closed. Pump is running with slurry flow closed-off which will
result in extreme heat generation causing damage and/or bodily
injury. The recirculation valve must always be open and material
flowing back into the tank when using the remote valve. A closed
remote valve in conjunction with a closed or plugged recircula-
tion will cause extreme heat resulting in damage and/or bodily
injury.

STARTING PROCEDURE:
CAUTION: See safety section of the manual (pages 2-4) before operating the
machine.
Before starting, open the recirculation valve, close discharge valve, disengage (turn off) the clutch, and place the
agitator control in the neutral position.
1. Set throttle about ¼ open.
2. Pull Choke control out.
3. Turn the key clockwise until the starter catches and engine fires.
4. Push the Choke control in for even running.
NOTE: This engine has a safety system which will shut the engine off if the
engine temperature goes above or if the oil pressure decreases below
an acceptable level.
AREA COVERAGE - MATERIAL CAPACITY:
To determine the coverage per load for any HydroSeeder®, three questions must be answered prior to the appli-
cation. First, is the job to be done “one step” (which is when the seed, fertilizer and mulch are applied propor-
tionally per load) or “two step” (which is when the seed and fertilizer are applied alone and then covered by
mulch as a second operation)? Second, at what rates (usually in pounds per 1000 square feet, or pounds per acre)
are the seeding materials to be applied? Finally, what are the loading capacities of the HydroSeeder®?
Application rates vary for different geographic locations, but in general, seed is applied at 6-10 pounds per 1000
square feet; fertilizer is applied at a rate of approximately 400 pound per acre; and fiber mulch is applied at
1500 to 2000 pounds per acre. (Note: There are 43,560 square feet in an acre). Local agronomists, agricultural
extension agents, or soil and water conservation officials should be contacted for more specific information on
application rates for a given area.
The following tables show loading versus coverage rates for the Finn T30. Table A shows rates for “one step”
applications. The coverage area is determined by the fiber mulch capacity of the HydroSeeder®, and the rate
at which it is applied. Table B shows the area coverage when seeding only, where little or no mulch is applied.
The coverage area is determined by the granular solids capacity of the HydroSeeder®, and the rate at which the
solids are applied.

LOADING:
CAUTION: Take care not to lose pens, lighters, etc. from shirt pockets or drop
pieces of paper or plastic bags into the tank, as these might plug
the slurry system.
1. With clutch disengaged (off) and agitator control in the neutral position, start engine and allow it to
warm up (See "Starting Procedure" on page 10).
2. Start filling the unit with water. When water reaches the top of the agitator shaft, move agitator control
to full reverse position.
Fill the tank with water from any stream or pond using a fill pump. When filling from a pond or stream
be sure to use a suction strainer to filter out contaminants which could damage the pump and unit. Other
sources of water:
A. Any pressure source, eg. fire hydrant. This unit is supplied with a 6” (15.2 cm) air gap fill port
but it is necessary to consult with local authorities before using water main in order to abide to
all local ordinances.
B. Water tanker.
3. Piping System Cleanout Procedure (Purging Line):
A. Remove discharge nozzle and coupler gasket from the remote valve coupler at the end of the
discharge hose (or from boom on the platform option).
B. Aim discharge hose (or boom on the platform option) into an open area away from any persons,
obstructions or high voltage power lines.
C. Open discharge and remote valves and close recirculation valve.
D. Increase engine speed to approximately ½ to ¾.
E. Engage (turn on) the clutch.
F. When discharge stream is clear, open recirculation valve and close discharge valve. After recir-
culation stream is clear disengage (turn off) the clutch.
G. Replace coupler gasket in the remote valve coupler (or in boom on the platform option).
4. Continue filling tank with water.
5. Increase engine speed to full RPM.
6. Start loading dry material, loading the lightest material first. Agitator control should be in full reverse
for mixing.
DANGER: Keep hands and arms away from the tank interior and agitator.
A. Seed - Cut the seed bag and dump contents into the slurry tank. (When using inoculant, add it in
the tank along with the seed.) When using quick swelling seeds load them just prior to applica-
tion.
B. Fiber mulch - Empty the entire bag in or cut bag and drop in the sections of fiber. The amount
of mulch to be used should be loaded by the time the water level is at ¾ full. If agitator stalls or
a high pitch squeal comes from the hydraulic system, reverse agitation to forward for a moment
to clear the obstruction, then return agitation to reverse.

14
CAUTION: Hydraulic system will overheat if agitator shaft is jammed for
extended period. This will damage hydraulic oil and system com-
ponents.
C. Fertilizer - Cut the fertilizer bag and dump the contents into the slurry tank.
D. All other additives - Consult with manufacturer for proper loading technique.
7. When all materials are loaded and in suspension, and the tank is full, move the agitator to neutral then
full speed forward to insure all material is mixed. It may be necessary to change the agitator direction
more than once to insure a thorough mixture.
8. After material is thoroughly mixed, slow agitator in forward direction to ½ to ¾ speed or enough to
create movement in all of the corners of the tank. Do not over agitate the slurry. Always discharge the
material with the agitator control in forward position.
9. Close the hatch lid on the slurry tank.
NOTE: If foaming occurs, reduce agitator speed.
PRIOR TO APPLICATION:
1. Operator should familiarize self with area to be seeded and develop a plan to insure uniform applica-
tion.
DISCHARGE NOZZLE SELECTION:
Nozzles are stored in the tool box. This HydroSeeder®is equipped with 3 nozzles - one long distance and two
ribbon fan nozzles. The following chart tabulates the approximate distance, width, and discharge time of the
nozzles when used with the platform option. When using the base unit these factors will vary according to the
type and length of hose being used.
