Introduction
Read this manual carefully to ensure correct steps are done to attach the applicator to the baler. This
applicator is designed to apply Harvest Tec buffered propionic acid. Use of alternative products may cause
complications and voids warranty. Complications may include inaccurate readings from the flow meter and
damage to system components.
The applicator can be installed on many square balers with the proper model number and installation kit.
Before installing the unit on the baler, make sure you have the proper installation kit (See the chart below).
Contact your local authorized dealer for specifications if you are unsure about your installation kit.
Left and Right sides are determined by facing in the direction of forward travel.

Installation of Applicator
Installation of Mounting Brackets, Tank, Pump Manifold & Hose Manifold
Model 744
Tank legs will be mounted to the back side of baler behind knotters and before the bale tensioner (Figure1).
Using Figure 2 as a reference, mark the two holes on each side of bale chamber that need to be drilled. Line
up saddle leg on each side to verify holes before drilling (Figure 3). Drill all four holes to 1/2” (13mm) in size.
Bolt legs to baler with 1/2” x 1 3/4” Allen button head bolts, flat washer, Lock washer, and nuts.
*Note: bolt head is on inside of bale chamber. Level top of leg before completely tightening bolts, Figure 4.
Bale Thrower - Additional Bracket
When baler is equipped with a bale thrower, bracket (001-4703QC) will need to be used. First secure the
kicker so it will not rotate when you remove the front pin on the hydraulic cylinder. Remove pin, install tank leg
over mount. Reinstall pin. Use part 001-4703QC which is a spacer that will go between the leg and side of the
baler to take up the space the throwers front hydraulic mount adds.

(25cm) from the side of the baler. Attach this holder with 1/4 x 1 1/4" self-tapping bolts. Place shield of top of
holder and rotate the shield to a 45-degree angle. Mark the location of the next holder’s position and install.
Four holes will need to be drilled below the tips using a 3/4" (19mm) hole saw or bit.

Install Kit 4507C
The shield for your baler will mount on the wrap guard as shown in the picture above. Remove the two outside
bolts on each side of the wrapper guard. Place bracket 001-4703G so pins are facing up and bolt through with
3/8 x 1-1/2" into bracket 001-4703G, through wrap guard, and into threaded holes on baler frame that the bolts
were removed from.
Installation of Plumbing
A. Intake
Locate parts bag 16. Use the 003-EL3412 on the bottom of the tank to route 1/2" line (002-9001) to the
003-A1212 or 003-EL1212 fitting used on the ball valve attached to the pump plate. Attach hose clamps
(003-9003) on both of the fittings.
B. Discharge
Route the 1/2" hose from the pump output toward the front of the baler and connect to the solenoid
assembly. Secure the solenoid assembly and hose along baler, positioning the solenoid as close to the
spray tips as possible- in an accessible location away from the incoming forage. Connect the 1/4" hose to
the outgoing side of the solenoid to tip assembly. Attach solenoid wire harness to solenoid and connect to
main baler harness plug labeled ‘SOL-1’.

Installation of End of Bale Sensor
Mount the 006-7401 sensor to the mounting bracket 001-4648SI for AGCO as shown below (Figure 1). Case
IH, New Holland, & John Deere and other balers will use bracket 001-4648SS. Mount the assembly on the
right side of the baler chamber. The face of the sensor needs to be parallel to the arm attached to the needles
(similar to Figure 2). Mount the sensor 5-8” from the pivot point, in a well-suited place, to reduce damage to the
sensor by needle arm when returning to the home position. Mark and drill two 3/8”(10mm) holes. Install the
sensor using two 5/16” x 1“allen head bolts, locks, and nuts. The end of the sensor needs to be no greater than
1/4” (7mm) away from the needle arm. Tighten nuts on sensor after adjustment.
.
Installation of Star Wheels
The pair of star wheels will need to mount on the bottom side as close to the front of the bale chute as possible
and at least 3/8" (10mm) away from any metal. They will need to maintain a safe distance away from the twine.
The star wheels will require two holes to be drilled per block. When drilling make sure to keep the wheel
square to the bale chamber. Any angle will cause stress on the wheel and will eventually cause the wheel to
work itself out of the block. Some balers may require a notch cut on the bottom of the bale chamber to mount
the star wheels in parallel and as close to the front of the chamber as possible- Star Wheel Installation
template reference is located in back of this manual.
Use the supplied bolts and place the carriage head inside of the bale chamber followed by lock and nut. Next
attach the star wheels to the bolts followed by flat washer, lock washer and nut.
The star wheel with the 6-pin plug will need to be placed on the left-hand side of the bale chamber, rotating the
star in a clockwise direction as bales move through the chamber.
Connect moisture harness to star wheels and run the harness along the baler frame towards the ISO Pump
Module (IPM) controller harness.

Tractor Setup
The general tractor setup of the 700 Series applicator can be seen above. The main harness of interest is the
tractor power/communication harness (006-765IC). This harness will connect at the tractor battery, to the ISO
Communication Module (ICM) mounted in the cab, a keyed power connection point, and connect at the hitch
area to the baler power/communication harness (006-765B). View below to see highlighted installation
instruction:
12V Battery Connection
ISO Communication Module
Key Power Connection
Harness Connection to Baler
The 12V battery connection must be at the tractor battery. Connection to
alternative locations such as an accessory port can cause problems with
applicator system.
*MUST BE CONNECTED DIRECT TO TRACTOR BATTERY TERMINALS*
The ISO communication module is to be mounted inside the cab. Other
mounting locations can lead to issues with weathering and operation.
Once installed and the system is powered, a green light will turn on with
the ICM module.
Ensure a solid keyed connection is found inside the cab and wired into.
Poor keyed power connection can result in applicator system issues.
The tractor harness connects at the hitch to baler power/communication
harness (006-765B). This will allow the system components to
communicate with one another. Ensure connections are debris and
corrosion free.
