INSTALLATION OF APPLICATOR
1. INSTALLATION OF MOUNTING BRACKETS, TANK, AND DRAIN/FILL LINE
Locate tank saddle legs (001-4442K & 001-4442D) as shown in figure 1. Fasten leg 001-4442D to
001-4442K with two 3/8 x 1 1/4” bolts, locks, flats, and nuts at point A.
Secure 001-4442K to the baler using a 3/8 x 1 1/4” bolt, flat, and nut through the existing hole shown
at point B on figure 2. Allow the gusset flange lip to rest on top of the baler tongue. Clamp both legs
to secure bracket to baler and drill six 9/16” on 001-4442K and two 9/16” holes on 001-4442D, using
the bracket as a guide. Secure the legs to the baler frame with eight 1/2 X 1 1/4” bolts, locks, flats,
and nuts. Tighten all hardware.
Locate the legs support bracket (001-4442E). Fasten the support to the baler, in the existing holes,
as shown at point C in figure 3. Use two 5/16 x 1” bolts, flats, locks and nuts. Tighten all hardware.

INSTALLATION OF MOUNTING BRACKETS, TANK, AND DRAIN/FILL LINE
Locate the tank and saddle assembly. Position the tank and saddle so that the side tank fitting is
towards the right side of the baler. The additional two weld-nuts on the saddle will then be facing
forward as shown in point E on figure 4. Fasten the tank saddle to the frame using four 1/2 x 1 1/4”
bolts, locks, flats, and nuts. Tighten all hardware.
Locate the pump plate assembly. Remove the four flange bolts holding the two pieces of the pump
plate together. Mount the pump plate mounting bracket (001-4646C) as shown below point E in
figure 5. Attach the bracket to the saddle using two 3/8 x 1” bolts, locks, and flat washers. Tighten all
hardware. Attach the remaining half of the pump and secure with the four 3/8 x 3/4” flange bolts.
Locate the drain/fill 3/4” hose, 3/4” elbow, 3/4” straight fitting, valve, quick coupler and mounting
bracket. Thread 3/4" elbow fitting (#003-EL3434) into side tank fitting. Run 3/4" hose from the
elbow down the frame to the bottom of the baler. Drill 1/4" holes to accept the valve holder bracket
and use 5/16” x11/4” self-tapping screws. Connect valve assembly to other end of hose. Place hose
clamps on both ends.

2. PLACEMENT OF SPRAY NOZZLE ASSEMBLY
Locate the spray shield holder (001-4704E2) and spray shield (001-4703GK). Center the spray
shield holder over the rotor. Clamp the bracket and drill two 7/16” holes point F on figure 6. Secure
the bracket using two 3/8 x 1 1/4 bolts, locks, flats, and nuts. Tighten all hardware. Install the shield
and secure using the two lynch pins (008-4576).
3. INSTALLATION OF HOSES AND GAUGE
Mount the gauge to the tank frame or the frame of the baler. If you mount the gauge to the baler
make sure it does not interfere with any of the baler’s operation, or be in an area where it could be
tripped over when servicing the baler. Connect the hose between the pump and the gauge. Run the
plumbing from the gauge to the check valve on the spray shield. Connect the disconnect to the end of
the hose from the gauge and to the check valve. The line will be routed along the front sheeting of
the baler next to the bale size indicator. Secure to baler using the padded jiffy clips provided. They
will be secured with two of the carriage bolts used on the baler’s sheet metal. Use hose clamps on all
connections.

4. INSTALLATION OF CONTROLS
APPLY RATE DECAL
Apply the rate decal that came in the bag with this book and place it just to the right of the speed dial.
LOCATION OF CONTROL BOX
Locate the control where it can be easily reached from the tractor’s seat. Adjustments for baling
speed and windrow conditions can be made as the baler is operated.
WIRING
Route the wire to the starter solenoid on all 12v tractors. Connect the green lead marked +to the hot
terminal on the starter. Connect the black lead to a good ground. DO NOT REVERSE THE LEADS.
Be sure to use a voltmeter to verify that you do have 12 volts running to the box.
NOTE: For tractors with 24v starters, connect the power leads to the tractor’s right hand battery. Do
not connect the leads to the starter. Connect the lead marked + to the positive battery terminal and
the lead marked- to the negative on the battery. Wiring connections to the battery normally results in
corrosion; terminal coating is recommended.
CAUTION: Do not run a pump or use an electronic control box directly off a battery charger. For
stationary use, the applicator can be connected to a new battery and the battery connected to a
charger.
OPERATION
The 436 applicator is very simple to operate. After installing the applicator, fill the tank with 5 gallons
of water. With control box connected to the applicator and the power cord hooked to the 12-volt
battery we can start the test. First flip on the toggle switch. You might hear the buzzing of the motor.
Turn the dial on the control box until the gauge starts to climb. By turning the dial clockwise the
pressure will go up. By turning the dial counter clockwise the pressure will decrease. With the
applicator spraying at about 30 PSI, look for leaks at all the hose connections and fittings. Using
water in this step instead of chemical will save you from wasting chemical and making a mess if leaks
are found. When you are comfortable with the operation of the controls you can set the applicator to
the amount of chemical you would like it to put on.
Message Light
The LED under the speed dial will be steady on when the applicator is running under normal
situations. If the light blinks on and off use the below information for the message.
Slow steady on and off blink: The system is attached to hay indicators (474A) or a foot switch.
This message means that the pump is paused. The light will come on constant once the baler is back
in the windrow.
Two quick blinks: The pump motor or pump harness is shorted.
Three quick blinks: Pump motor is over the current limit (10 amps).
Four quick blinks: Power is under current from a bad connection.
The control box must have the on/off switch toggled to clear the message after the fault has been
fixed to clear.

CALIBRATION
There are three things that you need to know when calibrating your applicator. First you
need know how many tons per hour you bale. Second you need to know the rate, or how
many pounds of product to apply for a given ton per hour. Finally you need to know what
tips to use and at what pressure to set the gauge.
DETERMINING TONS PER HOUR
Round Balers
1. Time 3 bales and average the time it takes to make a bale. Don’t include tying
time.
2. Estimate the weight of the bale.
3. Use the bale rate chart below to determine the tons you are baling per hour.
Example: You made 3 round bales and it took you an average of 2 minutes a
piece to bale each of them. Your baler’s operator manual tells you that an average
bale made by your machine weighs 1000lb. (Remember if the hay is dry it will
weigh less and if the hay is wet it will weigh more.) Using the chart on the following
page, cross-reference 2 minutes with 1000lbs and you will come up with 14 ton per
hour.
DETERMINE THE RATE OF CHEMICAL
The number of pounds of chemical required to be applied to a given ton of hay,
depends on the moisture and the type of chemical used. The moisture of the hay is
important in determining how much chemical to use. The wetter the hay the more
product is needed, the dryer the hay the less product is needed. By knowing the
moisture, you can make sure you are treating the hay correctly. Under applying will
save money but spoilage most likely occurs. Over applying will waste money
however, the hay will be saved. Some chemicals require more or less to treat the
same amount of hay. To find the exact number of pounds required, for a given hay
moisture, refer to the label on the drum or contact the manufacture. Harvest Tec
applicators come with the red, green, and blue sets of tips. If your chemical
requires rates other than what these tips deliver you will need to purchase them
through your dealer.

9
CALIBRATION REMINDERS
*Watch the pressure gauge as the setting will vary with tractor’s electrical output,
temperature and other factors.
*Check your application rate by measuring product used against actual tons baled.
REMEMBER, ONLY YOU CAN CONTROL HOW MUCH PRODUCT IS APPLIED
AND THAT WILL DETERMINE IF YOUR HAY WILL KEEP!!!
SELECTING TIPS AND SETTING PRESSURE
Once you have determined your tons per hour and the amount of chemical
needed for the moisture you are applying at, you can select your tips and
determine your gauge settings.
1. Multiply the tons per hour by the amount of chemical required for
the moisture you are applying at. This sum will give you the
application rate.
2. Select the proper set of tips from the application rate chart and
install them.
3. For the tips you have selected, you will need to keep the gauge at
the recommended PSI to achieve the proper application rate.
4. Set the pressure by adjusting the dial on the control box and by
reading the pressure of the gauge to match the desired rates.
The numbers on the dial are for reference only. Rate is
determined by watching the pressure gauge.
Example: You are baling at 12.5 tons per hour with your round
baler. The moisture that you are baling at requires you to apply 8
pounds per ton. Multiply the 12.5 tons x 8lbs. = 100lbs per hour.
Using the chart (lbs/hr) on the following page, you will notice the red
set of tips at 35 PSI will give you that output.

ROUTINE MAINTENANCE
1. Clean the tip strainers and main strainer every 10 hours of operation or more frequently if
required.
2. Depending on the product being used, the system may need to be flushed with water at a
regular interval (consult with manufacturer of the chemical.) If Harvest Tec product is being
used, flushing is not necessary.
3. Although the pump can run dry, extended operation of a dry pump will increase wear. Watch
the preservative level in the tank.
4. Cover the electronic cab control box on open station tractors if left outside.
5. Pump performance may start to decline after 400 hours of use. Rebuilding the pump is a
simple procedure if the motor is not damaged. Order pump rebuilding kit #007-4581.
6. If you are using bacterial inoculants, flush out system daily after each use.
7. Clean tank cap breather every 20 hrs or more frequently if required.
WINTER STORAGE
1. Thoroughly flush the system with water.
2. Remove the filter bowl and run dry until the water has cleared out of the intake side.
3. Remove the red plug from the bottom of the pump, drain, and run the pump for 30 seconds or
until it is dry.
4. Drain all lines on the outlet side.
5. Never use oils or alcohol based anti-freeze in the system.
6. For spring start-up, or anytime the pump is frozen, turn off the power immediately to avoid
burning the motor out. The pump head can be disassembled and freed or rebuilt in most
cases.
