Why choose a self-propelled wagon?

A self-propelled TMR mixer is certainly the most flexible and efficient solution in reducing the time spent on loading, mixing and unloading of the TMR. There are many reasons to switch to a self-propelled Storti. Below we list but a few:
The self-propelled machine condenses the work of 4 vehicles – tractor, mixer wagon, silage unloader and telescopic loader, with a clear saving in maintenance costs, number of operators required to perform maintenance and, not least, time.
A self-propelled machine is not a choice that binds you for the future, it adapts to all types of farms with no need for structural modifications.
The efficient front cutter with FPS system guarantees the loading of all types of product accurately and rapidly, without damaging the product structure
A self-propelled machine has significant residual value, even after many years of service. Management of all feeding procedures, comfortably seated in the cabin, with no need for switching from one vehicle to another.Our customers who have switched from trailed to self-propelled machines have reduced the time spent on feeding by 40%, and even improved the quality and accuracy of TMR production.

What’s the difference between a horizontal and a vertical wagon?

A mixer wagon is a tool that must be able to adapt to the farm needs, including:
– type of farming, cattle, milk…
– Available fodder, and type of preservation and storage
– Farm manager habits and beliefs
– Available workforce
Having said this, there are many differences between horizontal and vertical mixing;
– Cutting: the horizontal wagon is faster and cuts the fibrous ration cleanly.
– Mixing and softness: the vertical wagon has a softer and more voluminous mix.
– Unloading: the horizontal machine has a more constant and accurate flow, the vertical unloads with a pulsed flow.
– Dimensions: horizontal wagons are generally lower and more compact, take advantage of the volume and have easier access to the rear.
– Load capacity: while horizontal wagons have a size limit of about 24m³ and can adapt both to small and large mixes, vertical wagons can reach a volume of 44m³ but need a minimum amount that guarantees that augers are covered to ensure an efficient flow mix.

Why is the Mech Drive mechanical transmission used?

It’s a question of physics! Every transformation brings with it energy losses and the more that transformations take place in the transmission, the more energy losses there are. Now imagine that motion produced by a diesel engine is transformed into a flow of hydraulic oil which then circulates inside a circuit and is then reconverted into rotary motion by a hydraulic motor. This is what happens in hydraulic transmission and, as you can well imagine, all these transformations give rise to an enormous amount of lost energy, in heat, load losses and so on…
Storti was the first to understand the importance of lowering operating costs and fuel consumption, which is why it has equipped the entire range with the highly efficient Mech Drive mechanical transmission which, unlike hydraulic transmissions, converts outgoing motion from the heat engine through a cascade gearbox, with minimal loss of horse power. This leads to appreciable savings in terms of fuel, a reduced quantity of hydraulic oil and extended times between maintenance.


Overboost is a command placed in the cabin of our self-propelled machines that accelerates the rotation of the vertical augers. In practice, it is a cleaning cycle at the termination of unloading to prevent contamination between one load and the next.

How does the FPS system work?

The FPS, or Fibre Pick Up System, is one of the distinctive features of the cutters in Storti self-propelled machines which allows the efficient loading of all types of product by selecting the rotation of the cutter in a clockwise, or counter-clockwise, direction depending on the material to be loaded. With the FPS cutter, even the longest and most tenacious hay can be loaded by rotating the cutter upwards so as to lift the product and pre-cut it on the upper counter blade, so as to prevent locking the rotor during loading. Grass or corn silage is, however, loaded with a downward rotation of the rotor which, combined to a conveyor auger positioned behind the cutter, prevents the recycling effect of the spiral cutters. In this way the cutter blades cross the silage only once without damaging the structure of the corn. In practice, the cutter operates only as a scraper of the product, without cutting it further.   

What is the difference between the EVO and IIIa models?

The European Commission has been committed to addressing the problem of polluting emissions since 1999 through Directive 97/68/EC. The Directive mainly focuses on PM (Particulate Matter) and NOx (Nitrogen Oxides), and has been defined and amended through the promulgation of several Stages. Stage IV entered into force in 2014 and provides for the near total elimination of NOx. This offers the opportunity to improve our approach to the environment, while continuing to provide high-performance machines. The EVO model is equipped with Stage IV engines as required by European standards, and also includes the management of all CAN bus technology commands that allows intelligent and automated command sequences, as well as diagnostics with clear messaging on display in the cabin.

Dunker T1-T2-T3 S, L, Split… What is the difference?

The difference between Dunker S and L is, first and foremost, the diameter of the vertical augers – S means Small (narrow base) and L stands for Large (wide base). Having two different diameters leads to many other technical differences such as:
Reducers, gearbox and drive shafts – increasing the diameter also increases the size of the gearbox and of the entire transmission.   The L model allows a lower machine to have the same cubic capacity.
The chassis: the L model is clearly sized to reach a larger volume. Therefore, its chassis, axles, wheels and weighing system are sized accordingly.
While the Split model is the S model with the partially removable tank to facilitate transport in containers, with this configuration savings on transport costs can be made

How do I know how big I need my wagon to be?

The required volume depends on the type of product to be loaded and its quantity and, depending on the type of recipe, results can vary greatly. For example, if we consider a TMR for standard European dairy cows with an average of about 5 kg of dry hay per head, we have a feeding capacity of about 7 head/m³. If, however, we consider a recipe for fattening where, on average, we have 0.9 kg of straw per head, we can supply up to 19/20 heads per m³. More accurate calculations may be performed by evaluating both the distributed recipes and the number of distributions to be made during the day. Our technicians are available to assess your needs
