Umbilical Drag Hose Slurry System With RainWave™

Nevada's Umbilical Drag Hose System is ideal when you want to empty your effluent storage very quickly.  A mobile option, pump straight from storage and spread over multiple areas of the farm, and even over multiple farms without the limitations of fixed, in-ground piping.  It’s also ideal for farms who don’t have power running to their storage for an electric system, or for use in wet seasons where using a slurry tanker is not possible.

Nevada's unique umbilical drag hose slurry spreading system with RainWave™ is designed for damp soils.  Using a high capacity pump, effluent is pumped through a layflat hose to a low pressure RainWave™ slurry spreader.  The RainWave™ effluent spreader is attached to your tractor’s 3 point linkage, dragging the hose behind it.  The selection of layflat hose for these systems is critical.  Not only must the hose be abrasion resistant, it also needs a high tensile pulling strength and high working pressure.  
Maximise Effluent Pond Nutrients
Nevada Rainwave™effluent spreader
Nevada Rainwave™ umbilical drag hose systems give farmers the opportunity to apply large volumes of effluent at a low application depth.  This maximises the use of effluent pond nutrients without the risk of overflowing.  
Efficient, Effective Spreading
Nevada Rainwave™effluent spreader
It’s possible to apply over 1,000,000 litres in one day with no ponding or run-off!  Easily spread 10x the amount of a standard travelling irrigator.
Full Control Over Application
The Nevada Rainwave™ slurry spreader has a unique low pressure spread pattern which encapsulates nitrogen, making the best use of all the nutrients available.  You’ll have full control of the application, making it ideal for undulating and odd shaped paddocks.

Nevada Rainwave™ Slurry Spreader

By using low pressure and an oscillating fan pattern, the Rainwave™ slurry spreader achieves a wider spread and produces larger droplets, meaning virtually no wind drift, so nutrients are spread evenly.

What's more, by using the Rainwave™ slurry spreader, you'll get more from your nutrients!
How?  As the name suggests, the Rainwave™ uses low pressure to spread effluent nutrients in a gentle rain pattern.  This reduces volitisation so nutrients are not lost to the atmosphere.
