IMPORTANT :
To obtain the highest Precision while Spreading:
–he Speed sensor must be mounted on a wheel that is not subject to slip or spin during the
Spreading.
–Wheel pulse distance and spreading width should corectly entered into to monitor.
–HOLD signal will flash when the spreader is not out putting material.
–Enter the correct setting for Material Density, Door Height, Rate and Spinner speed, to
allow the Field Mate to calculate the correct chain speed to suit the required spreading
rate.
–Calibrate the Spreader using the DUMP screen. Feed out one tonne of material and adjust
the FLOOR FAC OR as required to ensure the System will spread accurately.

he FIELD MA E Spreader Rate controller and Area Meter has been developed to calculate land area, distance
travelled during spreading, while controling the speed of the floor chain to achieve a user defined spreading rate.
he meter will also record Spreading hours and timed stopped. While Spreading the meter can display the spreading rate
in hectare per hour and chain and spinner rpm as the desired spreading rate is controlled.
All measurements are metric.
A distance is measured via a magnetic wheel speed sensor. Shaft sensors are mounted on the chain and spinner motors.
Spreading on and off function is controlled by the in vehicle Fieldmate Run / hold switch.
o achieve the desired spreading rate the operator must enter the following:
- MA ERIAL DENSI Y.
- DOOR OPEN measurement.
- SPREADING RA E.
he FieldMate will compute the chain motor rpm to achieve the desired rate based on the 3 information sets entered
above.

Start a Job
Note: his system is operated by either pressing and holding or quick pressing the 5 or 6or reset or power
buttons.

1. urn On the system using the power button.
2. urn on the oil valve using the control valve switch ( mounted in cab from the FieldMate wiring loom).
3. At power up one of the following screens are displayed. One screen is a HOLD screen, the other screen
is a RUN spreading.
4. Clear any information from a previous job by holding the RES switch
for 5 seconds. Only job spreading information is reset, all other user
setting are unaffected.

1. Use the HOLD / SPREAD Switch to start spreading. Spreading will only occur when this
switch is in the SPREAD Position and the Spreader speed is above 1 km/hour.
When in spreading mode the main screen will display the working rate and the state of the chain
motors and the spinner motor.

Information recorded
Page 8
At any time during the spreading operation a report of the work done is reported in the REPOR Screen.
Using the arrow buttons at move to the REPOR screen, quick press the power button to enter the report
display screens. Spreading information reported:
- Area
- Distance spreading and not spreading
- Weight of material spread
- ime spreading, total time the job
- Wheel pulses for the current job
- Size of wheel size and width of machine
- Date and time the job was started
- Material details spread. Rate, Density etc.

Dump Mode
Page 9
Dump mode is used to empty the spreader or to calibrate the spreader to output 1 tonne of material.
Calibrate the Spreader to output 1 tonne for material.
1. Goto DUMP mode.
2. Quick press the power button to enter DUMP mode.
3. Quick press the 5 button will put the spreader in to Dump onne mode. In this mode the ONNE label
will flash.
- Hold down the 5 or 6buttons to make the chain start.
- When the spreader has output 1 tonne the chains will stop.
Note 1: he weight and material output and based on the current material being spread. Accurate weight
calc is based on the exact door open measurement setting and the correct material density.
Note 2: he spreader must have a one tonne amount of material placed in the spreader if this calibration is
to be accurate. hen this 1 tonne is measure out to test spreader output calibration.
Note 3: If the Spreader stops at 1 tonne but with 100kg of material left in the spreader then this is
concidered a 10% over weighing. o fix reduce the Floor Factor by 10%.
Note 4: If the Spreader has output all the material when the weight is 900kg, then the spreader is
concidered to be 10% under weighing. o fix increase the Floor Factor by 10%.
Keep working with the FLOOR FAC OR number until 1 tonne of material is output from the spreader
when a 1 tonne bag is entered into the spreader.
Chain RPM during DUMP MODE. Hold the
5or 6buttons to achieve the desired RPM.
Speed of the Spinner in DUMP MODE. In a win floor system, this is under Mechanical
control. In Single floor mode the DUMP RPM is set in the SE UP Screens.
Weight out put by Spreader as calculated by the monitor, based
on internal settings and Material density and door opening.
he Chain RPM and rotations of the Chain motors are counted.
ONNE flashes when in dump tonne mode.

Dump Mode
Page 10
Empty the Spreader using DUMP MODE.
1. Goto DUMP mode.
2. Quick press the power button to enter DUMP mode.
3. Quick press the 6 button will put the spreader in to EMP Y mode. In this mode the EMP Y label will
flash.
- Hold down the 5 or 6buttons to make the chain start.
- he Monitor will run the Chains until the user quick presses the power button. Or the chain motors are
stopped. Stop the chain motors by holding down the 5 or 6buttons.
Chain RPM during DUMP MODE. Hold the
5or 6buttons to achieve the desired RPM.
Speed of the Spinner in DUMP MODE. In a win floor system, this is under Mechanical
control. In Single floor mode the DUMP RPM is set in the SE UP Screens.
