IMPORTANT :
To obtain the highest Precision while Spreading:
– The 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 FACTOR as required to ensure the System will spread accurately.

The FIELD MATE 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.
The 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.
To achieve the desired spreading rate the operator must enter the following:
- MATERIAL DENSITY.
- DOOR OPEN measurement.
- SPREADING RATE.
The FieldMate will compute the chain motor rpm to achieve the desired rate based on the 3 information sets entered
above.

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

1. Turn On the system using the power button.
2. Turn 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 REST switch
for 5 seconds. Only job spreading information is reset, all other user
setting are unaffected.

Page 7
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.
NOTE: THE OIL CONTROL VALVE SWITCH MUST BE ON TO ALLOW MOTORS TO
OPERATE.
Information recorded
Page 8
At any time during the spreading operation a report of the work done is reported in the REPORT Screen.
Using the arrow buttons at move to the REPORT 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
- Time 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.
