Tow and Fert – Multi 4000

Return to Previous Page

This unit is designed to be towed by a tractor of minimum 110hp. It uses the PTO at 1000rpm for mixing & agitation and hydraulics to run the specifically designed 3” trash pump found on all other Tow and Fert models for spraying. With the patented agitation technology in the tank, you can simply empty 1 tonne bags of fine particle fertiliser directly into water without any pre-mixing or messy work. Combined with the optional crane, you can load 5 tonne of fertiliser product into the Tow and Fert in just 15 minutes. With up to a 24 metre spread, the Multi 4000 can cover 1 hectare in just 3 minutes at 12 km/hr (8 mph). With a capacity of up to 40 hectares per load, this Tow and Fert makes light work of a large job.

Product description

The Tow and Fert product range enables farmers to easily and quickly mix and apply foliar and fine particle fertiliser.

Numerous research papers show the significant benefits of applying soluble fertilisers as a foliar spray, and also of applying non-soluble fertilisers as a fine particle blend rather than in its usual coarse ‘ag’ grade. However the practicality of mixing and applying these fertilisers with traditional boom sprayers and solid fert spreaders has put the job in the ‘too hard’ category. The Tow and Fert range solves these issues and offers farmers an easy, economical and convenient way to apply these ‘hard to deal with’ fertilisers. This means that the financial and animal health benefits of fine particle and foliar fertilisers can be gained without complicating your farming practices. Too easy!


Product Details

The Tow and Fert range has many features which set it apart from a traditional boom sprayer. The mixing tank features patented powerful agitation, with mix ratios of up to 1 part water, 2 parts fine particle fert possible. The booms also feature our patented recirculation system, this means the booms continuously recirculate regardless of it the nozzles are spraying or not. These and many other features have been incorporated into the design of the Tow and Fert range to make mixing and applying fertiliser fast and convenient.


The Multi 4000 has an optional 1-tonne HiAb crane and optional braked axles.


All fittings used on the Tow and Fert are cam-locks for ease of use in the field and for cleaning.  Nozzles are easily interchanged for varying spray rates.


Construction of build is a galvanised chassis, UV resistant plastic tank and a combination of stainless steel and plastic in all areas that come in contact with fertiliser.


With each Tow and Fert, comes calculator software to determine your mix ratios before you even start filling the machine.  You can enter in rates per hectare of each desired product, and let the calculator do the math.
