Computer control system

Smart. Accurate. Control.

The all-new SAM computer control system is based on industry proven technology and decades of international experience. 

The Topcon Athene offers fast, accurate response in a user-friendly control and monitoring system. It gives precise control for spreading all types of fertiliser, manure and animal waste. This technology means the correct application rate is applied regardless of changes in forward speed or changes in product density.

This technology is simple and intuitive. The system is ISOBUS so it can function with any compliant tractor console. Or we can provide a separate, generous, 8 1/2" colour touch screen display. By adding the load cell module, the fully integrated system will also allow dynamic rate control. This uses the weight of product to constantly check spread rate accuracy.

Your options for set-up:

A) Volumetric rate control only

This system can be used as a rate controller. Either by entering a known product density or selecting the product from a pre-defined list. Spreader functions like spinner speed and border control are all monitored and operated through the touch screen.

Please note: If you are after a simple rate controller, the Whitehead V3 is also a great alternative.

B) Dynamic / static rate control, including integrated load cells and your own ISOBUS tractor display

This includes fully hydraulic floor speed and load cell rate control. It measures the weight of product in the spreader, the floor speed is then automatically adjusted to achieve the correct application rates. This advanced control means extra precision. You are getting automatic rate calibration and gaining maximum value from what you are spreading out. Most new tractors are ISOBUS compatible, meaning the system plugs straight in and can be controlled from your existing console.

C) Dynamic / static rate control, including load  cells, GPS aerial and our Topcon X25 display screen

This set-up gives you the above functionality as well as a GPS aerial for proof of placement, light bar and field mapping of your jobs. Record all your spreading details for improved traceability and record keeping.

An inline oil filter is recommended.

This brochure has a simple tick chart explaining what is included with each set-up.


Smart Features

    Large 8 1/2" screen

    A generous 8 1/2” colour touch screen display, with anti-glare, can be provided for the cab of your tractor.

  • Integrated load cells
    Integrated load cells

    Integrated load cells continuously measure the weight of product in the spreader. The floor speed is then automatically adjusted on-the-go, to achieve the correct application rates. Optional.

  • ISOBUS interface
    ISOBUS interface

    The clear and user-friendly ISOBUS interface has simple and intuitive operation. It is an ISOBUS ICU which means it can connect to most modern tractors.

  • Spinner speed monitoring
    Spinner speed monitoring

    Gives you great visibility over what is happening with your spinners. Your screen shows whether spinners are stationary or operating, and at what speeds.

  • Mapping

    The mapping clearly shows where you have been in the field. Light bar guidance keeps you on track using AB lines. These allow you to optimise your coverage.

  • Proof of placement

    For better reporting and compliance, your proof of placement data is available to download. This gives accurate coverage and peace of mind.

  • Border control

    Reduces spinner speed on the left hand disk which decreases spread width. This is helpful for spreading beside borders and waterways.

Optional extras

  • GPS aerial for proof of placement
  • X25 Touch screen
  • Load weigh scales
  • Inline oil filter

GPS aerial for proof of placement

Adding a GPS arial ensures you have proof of placement. It also provides lights bar and field mapping of your jobs. This means you can record all relevant details for improved traceability and your record keeping.

You may be able to use your existing GPS aerial if you have one.

X25 Touch screen

If your tractor is ISOBUS you may choose to run the computer control system through your existing cab screen. Alternatively you can purchase the 8 1/2" anti-glare colour touch screen. This generous size makes controls easy to see and operate on-the-go.

Load weigh scales

Most farmers purchasing the computer control system add the weigh scale module. This means the actual weight of product in the bin is being weighed at all times. Then these figures are being used by the system to check spread rate accuracy as you go from the cab.

Inline oil filter

This filters the oil prior to getting into the system. Recommended.
