Introduction

The Harvest Tec Model 442 applicator is designed to apply buffered acid-based hay preservatives. It can also be used to apply water-soluble inoculants, but must be flushed on a regular basis when applying these types of products. There are two models of the 442, a 100 litre version and a 220 litre version. Before installation, ensure you have the correct version for your baler.

REFERENCE CHART

TOOLS NEEDED

For installation of this applicator, the following tools will be required:

• Standard wrench set
• Standard socket set
• Standard screw driver or 5/16" nut driver
• Side cutter
• Hose cutter
• Crescent wrench
• Hammer

INSTALLATION

Locate the cross support on the front shelf of the baler. It will butt up against the step-up on the shelf and line up flush with its upper surface. Mark and drill a 9/16" hole on each side sheet to hold the cross piece in place with two 1½" by 1¼" bolts and secure with lock washers, fender washers, and nuts provided.

[Textual description: The image shows a black metal cross support piece positioned on the front shelf of a baler, with arrows indicating where holes should be drilled for mounting.]

Locate the tank and frame on the shelf. Center it from side to side. On 55-gallon models, the tank positioning going from front to back is set by lining up the front base holes with the holes in the cross support. On 25-gallon models, line up the front tank legs with the front corner of the baler's shelf. Mark and drill all base holes with a 9/16" drill. Use the 1½" by 1¼" bolts, lock washers, fender washers, and nuts provided to secure the frame.

[Textual description: Two images are shown. The left image depicts the installation of a 55-gallon tank system on a baler, showing the tank, frame, and mounting points. The right image shows the installation of a 25-gallon tank system, highlighting the front tank legs aligning with the baler's shelf.]

(Please contact Harvest Tec for additional parts if mounting on a Bale Slice equipped baler)

Locate the spray shield (part number 001-4810B) and the spray shield holder (part number 001-4810BRH). The assembly will mount as shown in Figure 1, directly above the baler's pickup. Four 3/8" holes need to be drilled to mount the shield holder to the baler (Figure 2). Mount the shield holder using four 5/16 x 1 1/2" bolts, locks, flats, and nuts. Attach the shield to the holder using the two supplied lynch pins.

[Textual description: Figure 1 shows the spray shield assembly mounted on the front of a baler, positioned above the pickup mechanism. Figure 2 illustrates the drilling points and dimensions (e.g., 0.375 x2, 0.500, 6.500, 8.000) for mounting the shield holder to the baler.]

On the 220 litre unit, connect the ½" hose between the tank and the intake side of the pump/filter. Mount the gauge to the tank frame or the baler frame, ensuring it does not interfere with baler operation or create a tripping hazard. Connect the hose between the pump and the gauge. Route the plumbing from the gauge to the right-hand nozzle along the front sheeting of the baler next to the bale size indicator. Secure with padded jiffy clips. Run the line to the center and left-hand nozzle. Use hose clamps on all connections.

Locate the fill valve bracket and quick coupler on the right-hand side of the baler. Bolt it to the sheet metal above the pick-up using the corner bolt. Route the line into the side fitting at the right-hand of the tank. Secure the transfer line to nozzle line using black ties and padded jiffy clips. Use the larger hose clamps provided at both ends.

[Textual description: An image shows the fill valve bracket and quick coupler mounted on the baler, with a green arrow pointing to the connection.]

Apply the rate decal, provided in the bag with this manual, just to the right of the speed dial.

Locate the control box 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.

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. Use a voltmeter to verify that you 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 442 applicator is very simple to operate. After installing the applicator, fill the tank with 5 gallons of water. With the control box connected to the applicator and the power cord hooked to the 12-volt battery, you 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. Turning the dial clockwise increases pressure; counter-clockwise decreases it. With the applicator spraying at about 30 PSI, look for leaks at all hose connections and fittings. Using water in this step instead of chemical saves you from wasting product 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 apply.

Message Light

The LED under the speed dial indicates operational status. If the light blinks on and off, refer to the information below 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.

CALIBRATION

There are three things you need to know when calibrating your applicator: how many tonnes per hour you bale, the application rate (litres of product per tonne per hour), and what tips to use and at what pressure to set the gauge.

DETERMINING TONNES PER HOUR

Round Balers

1. Time 3 bales and average the time it takes to make a bale.
2. Estimate the weight of the bale.
3. Use the bale rate chart on the next page to determine the tonnes 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 states that an average bale made by your machine weighs 550 kg. (Remember, if the hay is dry it will weigh less, and if the hay is wet it will weigh more.) Using the chart below, cross-reference 2 minutes with 550 kg, and you will come up with 17 tonnes per hour.

SELECTING TIPS AND SETTING PRESSURE

Once you have determined your tonnes 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 tonnes 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 20 tonnes per hour with your round baler. The moisture that you are baling at requires you to apply 4 litres per tonne. Multiply the 20 tonnes x 4 litres = 80 litres per hour. Using the chart, litres per hour with three nozzles, on the following page, you will notice the green set of tips at 40 PSI will give you that output.

DETERMINING THE RATE OF CHEMICAL

The number of litres of chemical required to be applied to a given tonne 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 ensure 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 manufacturer. 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.

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 tonnes baled.

REMEMBER: ONLY YOU CAN CONTROL HOW MUCH PRODUCT IS APPLIED AND THAT WILL DETERMINE IF YOUR HAY WILL KEEP!!!

LITRES PER HOUR WITH THREE NOZZLES

MAINTENANCE

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.
