The self-propelled fertilizer spreader Accura ST works with a distribution range of up to 42 meters, equipped with an electronic motor of 220 hp in the 5 m³ version and 260 hp in the 7 m³ version. To minimize the corrosive effect of fertilizer, its hopper is made of stainless steel, as well as its chassis, platform and handrail. Besides, it has the Belt Free system, which ensures constant feeding of the spreading discs, in addition to the exclusive Coaxial Distribution Adjustment System (CDA) to facilitate application rate regulation and to perform accurate fertilizer and seed spreading.

CDA: unmatched accuracy

Different fertilizers, variable application rates, multiple working widths - your fertilizer spreader must adapt quickly to different needs. The coaxial distribution adjustment system - CDA, part of the Accura ST fertilizer spreader, helps address these challenges by providing easy adjustments. There are two important features that make the CDA system unique: ## NewLine##
  1. At the base of the hopper, the outlet allows quick adaptation to various fertilizers and working widths, adjusting the fertilizer drop point on the distribution discs.
  2. Specially designed measuring sockets, close to the center of the discs, allow multiple supply points on the blades, ensuring a constant fertilizer flow and a uniform pattern. In addition, the working width can be changed in a few seconds: just rotate the hopper base to change the fertilizer drop point on the disc. This operation is simple and does not require the use of tools.

Extra-slow agitator

The Accura ST fertilizer spreader is equipped with a unique type of agitator, 100% sealed, which regulates the supply of fertilizer and seeds to the machine's outlets, providing improved distribution flow. Besides, the agitators used in the Accura ST preserve the fertilizer's physical characteristics, as they rotate at just 17 rpm. Granules are handled smoothly, significantly reducing mechanical damage, in addition to preventing the formation of dust. The preservation of the fertilizer's characteristics is extremely important, as it allows the system to achieve perfect spreading.

More accuracy with the Accura ST guiding brush

Adjustment of the uniform spreading pattern takes place by means of a lever that adjusts the fertilizer drop point on the spreading disc. To ensure an accurate drop point, guiding brushes accompany the fertilizer flow until it drops onto the pallets. These brushes are already assembled in the distributor's coaxial spread adjustment system - CDA, thus, they do not require adjustments for each equipment use, ensuring its integrity. They are also important because, in addition to minimizing the influence of the wind and preventing the fertilizer from bouncing off the disc, they prevent the segregation of particles during application.

Reduced turbulence

The harmonic alignment of Airfins deflectors on Accura ST self-propelled fertilizer and seed spreader discs reduces unwanted air turbulence generated by rotating discs, ensuring smooth and accurate distribution, even with pressure sensitive granules. In addition, grain crushing or breaking effects are reduced to a minimum, while the high disc speed is maintained, ensuring that the grain or seed reaches an ideal initial speed. Accura 14000 fixed blades also work to ensure spreading precision and uniformity: even the most delicate fertilizer is able to maintain its flight properties. It is noteworthy that all distribution discs available for the Accura 14000 have these characteristics, what varies is the size of the blade that determines the application width.

Protection grids

Protection grids

The protection grids used in the Accura ST spreader hopper help prevent the entry of impurities and the agglomeration of inputs that may damage the belt or other components. They can be removed quickly, since they are modular: formed by 4 screens of the same size. Besides, Accura ST is fitted with chains located before the limestone module, which allow separating the limestone to achieve a more uniform spread. Also, the two protective deflectors of the belt, arranged in the longitudinal direction related to the machine's direction of travel, prevent excessive pressure of the product (fertilizer) on the belt during spreading, increasing its service life, as well as the drive system's longevity.

Hopper access

To ensure operator safety and accessibility to the main hopper, the Accura ST self-propelled fertilizer spreader has several features, namely: a) a tilting ladder with a hand grip, located on the front of the machine, which, is retractable for transport and during operation; b) a high-resistance non-slip platform, which provides safety to the operator against falling and sliping when checking the spreader main hopper; and c) a handrail with a rounded bar and a smooth surface installed on the non-slip platform, which aims to reduce the risk of accidents with people, preventing them from falling off the machine.

Hopper cover

The Accura ST self-propelled fertilizer spreader has a protective cover located on the side of the hopper, which is manually activated directly from the ground by the operator. This cover is essential for protecting the product from impurities entering in the hopper, humidity, rain, among others, providing peace of mind to the farmer with regards to the various weather conditions. In addition, the high quality of its material ensures long durability, especially when regular maintenance measures are observed (such as periodic cleaning, for example), resulting in an excellent cost-benefit to the Accura ST. It is an easy-to-handle cover, which stands out for its versatility, in addition to being manufactured in a practical material, which makes cleaning easier.

MWM engine

Equipped with a 6-cylinder MWM 6.12 TCE engine, the Accura ST self-propelled fertilizer spreader meets pollutant emission control standards MAR-I. In addition, the ST 5000 model comes with 220 hp and optional for 260 hp, while the ST 7000 version comes with 260 hp. Added to this, the fact that the 12-cylinder engine of the six-cylinder series has features such as electronic injection system (Common Rail) and standard equipment: starter motor, alternator, electrical harness for interface with equipment and fuel prefilter with water level sensor.

Belt Free System - BF (Free belt)

The control hopper of the Accura fertilizer and seed spreader has two sensors that identify the pre-selected maximum and minimum product levels, so that when the product reaches the minimum level, automatically, the belt starts to fill up the control hopper to the preset maximum value. This way, it is possible to obtain great savings with respect to the belt wear, since it is only activated when necessary, differently from what happens in competing machines. In addition, the CDA system of the Accura ST distributes the product dose through horizontal outlets controlled by electric actuators, which ensures constant application rates: other machines, on up or down sections, can move more product to the control hopper, causing product overdosing or underdosing in the applied area.
