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 aler tongue. Clamp both legs to secure the bracket to the 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, Pump Plate, and Drain / Fill Line (continued)
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 a 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” x 1 1/4” self-tapping screws. Connect the valve assembly to another end of the 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 Plumbing

A. Intake
Use the 003-EL3412 on the bottom of the tank to route 1/2” line (002-9001) to the 003-A1212 fitting on the ball valve already attached to the pump plate. Attach hose clamps (003-9003) on both of the fittings.
B. Discharge
The three – 1/4″ hose assembly will be used to attach the pumps to the spray nozzles. The pump order is, from closest to the filter bowl, 1,2, and 3. Pump 1 will attach to the three main nozzles. Pump 2 will use the green hose and Pump 3 will use the blue hose to attach to the auxiliary nozzles.
C. High and Low Output Tips
Your baler comes with two sets of tips: a low setting and a high set.

• The low set will cover outputs of 32 to 440 lbs/hr or approximately 8-27 tons/hour.
  Install the following tips for low output:
  Clear hose to silver tips on all three connected nozzles.
  Green hose to green tip.
  Blue hose to red tip.

• The high set will cover outputs of 84 to 632 lbs/hr or approximately 21-40 tons/hour. Install the following tips for high output:
  Clear hose to white outside tips and orange middle tip.
  Green hose to blue tip.
  Blue hose to gray tip.

Refer to Tip Output under APPLICATION RATE of the control unit to calibrate
Installation of Moisture Sensing Pads

1. If your baler is equipped with bale shaping pads, remove the disc and use the existing hole (may need to be drilled larger, 3/4″) to install new moisture sensing discs.

2. If your baler is not equipped with bale shaping pads you will need to drill a hole in the chamber directly behind and above the starting roll (Figure 1).

3. The mounting hole will be 3/4″ in diameter. Use a plastic pad (006-4641F) and place it into the baler to use as a template. The bottom edge of the pad will be placed 1” up from starting roll and 2” from the back of the bale chamber. (Figure 1)

4. Locate the 006-4641G. The piece will need to be cut down to size. Use the already machined line in the bushing to cut off the small piece shown above.

5. Depending on the baler the bolt may need to be trimmed for proper fit.

6. Tighten all of the hardware to 50 ft/lbs.

7.  Make sure that the plastic pad is protecting all metal surfaces of the disc from touching the baler.

8. Run the moisture wire harness (006-4640G) from the pump plate area to each disc securing it with cable ties.

9. Apply silicone over nuts and washers.

5. Power Cable and Main Wiring Harness Installation

1. Connect the power harness (006-4640A) to the battery (12 volts) using the red wire with fuse to the positive side and the black wire to the negative
   a. The power harness must be connected to the battery! The unit will draw more amps than convenience outlets can handle. Any modifications of the power harness will void the system’s warranty. CONTACT HARVEST TEC BEFORE MODIFICATIONS.
   b. This unit will not function on positive ground tractors.
   c. If the unit loses power while operating it will not keep track of accumulated pounds of product used.

2. The power harness (006-4640A) will run from the tractor battery to the hitch. The power harness (0064660R) will connect to the tractor power harness (006-4640A) at the hitch. Run the Communication harness (006-4660N)from the cab to the hitch. This wire will connect o the Communication harness (006-4660S). These wires ill run together to the Baler Mounted Processor (006-4671RB).

3. Connect the Communication harness (006-4660N) to Bluetooth Receiver (030-4672A) mounted in the cab.
   a. Mount Bluetooth Receiver (030-4672A) in a safe location as close to the iPad as possible in the cab.

4. Connect Flow Meter (006-4725A) and pump harness (006-4660Z) to the Baler Mounted Processor.

5. Attach moisture cable (006-4640G) to Baler Mounted Processor.

6. Install Baler Mounted Processor in pump plate using 5/16” lock, nut, and flat washers.

NOTE: The plugs on the Baler Mounted Processor must face down. Failure to mount correctly will void the system’s warranty.
SYSTEM WIRING DIAGRAM

Installation of the Control

Installation of Bluetooth Receiver
Locate a safe location in the cab of the tractor to place the Bluetooth Receiver (030-4672A). The recommended location is as close to the iPad being used as possible.
Connect the communication wire (006-4660N) to the bottom of the receiver.

Optional Touch Screen Display
Use a suction cup mount (001-2012SCM) to position the monitor in the cab. Make sure the glass is clean before installing the suction cup mount. If an open-cabbed tractor is used, use the supplied #10 screws for installation on the fender. If the unit is mounted on a fender it will need to be removed at night and stored in a clean, dry area. Use the Ram mount (001-2012H) swivel- positioning nut to tighten the entire assembly. Adjust it so that you can view the entire screen and be able to use the touch screen without interfering with other tractor functions.
Connect the communication wire (006-4660N) to the bottom of the terminal.

Installation of Display Cable Harness
On the bottom of the touchscreen display, you will find the main display wire plug. The harness (006-4660N) will need to be attached to this plug and run through the cab towards the hitch where it will connect with its matching harness (006-4660L) from the BMP.

Maintenance

1. Clean the tip strainers and main strainer every 10 hours of operation.
2. Depending on the product being used, the system may need to be flushed with water at a regular intervals (consult with the 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 automatic cab terminal on open station tractors if left outside.
5. Pump performance may start to decline after 400 hours (5000 bales on large round balers) of use. Rebuilding the pump is a simple procedure if the motor is not damaged. Order pump rebuilding kit #007-4581 for the automatic unit.
6. If you are using bacterial inoculants, flush your system daily after every use.
7. Clean the tank cap every 10 hours of operation.

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, if 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.
7. Disconnect power from the system.
8. Remove the display from the tractor and store in a warm, dry place.

Backup Fuse

The Model 463 is equipped with a backup system if your display is not functioning. This function is intended for use only as a temporary means for application and not as a way to apply preservatives over multiple fields or for a lengthy amount of time. The baler-mounted processor has a location for a backup fuse on the same side as the pump and flows meter harness that bypasses all other system inputs and applies preservatives using one pump (Pump Three) at a constant lbs/hour shown below. These values are based upon an input voltage of 13.5 DC. Insert at least a 10 amp up to 20 amp fuse (3 AG style) into the backup fuse port to activate the bypass. The system will not turn off or pause until the fuse is removed. The main fuse must also be functional for the backup fuse to work.
