Greenback Magnum Travelling Irrigator

The Magnum is a powerful irrigator, incorporating a traditional travelling irrigator, with added value of the power of the powerful rain gun.  With a wetted width more than twice as wide as a traditional travelling irrigator, the Magnum offers application rates and depths competitive with sprinkler systems.  
Nevada Fertigator™


  • Labour requirement significantly reduced
  • Can achieve average application rates of 10.0mm/hour and application depths as low as 3.2mm/pass
  • Wetted widths up 80 metres, twice that of a standard travelling irrigator
  • Irrigate effluent in a single nutrient rich state without the need for expensive separation systems
  • Can provide a range of application depths and rates to suit soil conditions through simple travel speed and nozzle size adjustments.
  • It is a simple concept that is proven to be robust and reliable
  • Is capable of operating at pressures and flows provided by traditional effluent pumps extensively used throughout the country
  • Option of 300 or 400m Wire Rope

Remote valve switch (optional)

The remote valve switch lets you switch between one irrigation line to another (or bypass back to the pond) without turning off the pump.  This is made possible with use of a soft close switching system eliminating any potential pressure spikes. It’s so simple - just activate it from your mobile phone!
  • 75mm Y Valve
  • Powered by a 12 Volt battery
  • Free app download for IOS and Android phones
  • No internet connection required
  • Remote valve switch can be controlled by multiple mobile devices
  • Allows one person to operate a drag hose system
  • New Zealand made

Benefits of Travelling Irrigators in New Zealand

Irrigation is an essential component of dairy farming. It encourages productivity and as a result, profitability. Furthermore, it assists with pasture production, which leads to increased generation of milk.

  • Using an effluent irrigation system regulates the pressure of the effluent to create uniformity. An even spread is vital for maximum productivity.
  • Travelling irrigators replace the need for manually spreading effluent over pasture. You save money and time with efficient equipment. Furthermore, evenly spreading effluent reduces wastage and ensures sufficient fertilisation of your soil.
  • Travelling irrigators allow farmers to use their resources wisely, helping the environment by recycling effluent waste into pasture nutrients and significantly increasing production.

Tips for Getting More Value Out of Travelling Irrigators in New Zealand

Apart from acquiring the necessary equipment to enhance your farm's efficiency, you require a little assistance with the conditions for maximum results. Follow these tips to ensure you’re gaining the most out of your travelling irrigation.

  • You should consider monitoring the soil and its moisture levels. Coupled with reliable weather forecasts, it allows you to take advantage of rainfall times, saves you precious time on irrigation days and money in the form of pumping costs.
  • It’s ideal to irrigate when conditions are still. Strong winds affect spray patterns causing the application to change by up to ten per cent. Distribution uniformity is crucial and can be attained through 50 to 60 per cent lane spacing in moist conditions and 30 to 50 per cent spacing in windy weather. Managing the sector angles reduces water wastage and tracking issues.
  • With regards to travelling irrigators, selecting the correct sprinklers is critical. The diameter, height and spacing are essential factors to ensure uniform distribution. The manufacturer determines the operating pressure and should be implemented to save pumping costs. If not, the consistency of distribution will suffer.

We Supply Quality, Durable Travelling Irrigator Hose

The selection of travelling irrigator hose, or layflat hose for umbilical irrigation systems is critical.  Not only must the hose be abrasion resistant, it also needs a high tensile pulling strength and high working pressure.  Our quality, durable layflat hose is manufactured in Germany for agricultural and harsh industrial environments.  Normally used as a drag hose on umbilical irrigation systems, our travelling irrigator hose offers outstanding abrasion resistance, chemical/hydrocarbon resistance and huge torsional strength for dragging.
