Grunner Presents Functional Prototype of Ethanol-Powered Smart Machine, Launches S Series Models and Announces Consortium with Mercedes-Benz

(Grunner Energia/EAE Maquinas (Google Translation)) The company also has new features in its after-sales structure and strengthens its partnership with Michelin, which nationalized the manufacture of the tire used in Smart Machines.

During Agrishow 2025 , one of the largest agribusiness events in Latin America, which takes place from April 28 to May 2, in Ribeirão Preto (SP), Grunner presents at its stand the functional prototype of the ATR E , with an exclusive system developed in partnership with DSA , the first Smart Machine powered by ethanol.

At the 2024 edition, the Agrishow audience learned about the model's concept; now, with improved production, the ATR E is ready to enter field operation in the company's largest open-air laboratory at the beginning of the second half of the year. The technology meets the MAR-1 specifications, without the need for Automotive Liquid Reducing Agent (Arla) and without the risk of fire or shutdowns due to the Euro VI regeneration system.

Grunner will also be presenting new models of Smart Machines from the S Series during the event . Among the highlights is the new concept of the ATR S Line , presented at the fair with an electronic scale for precise weighing during harvesting and the digital rearview mirror ( Mirror Cam ), a feature already widely used in the transport sector and which is now reaching the field, providing greater visibility, safety and ergonomics for the operator.

“This technology offers expanded vision, eliminates blind spots and improves operations even in low light conditions or dusty environments, common scenarios in the daily routine of sugarcane harvesting”, highlights Grunner’s Commercial and Operations Director, José Reche.

Another launch at the fair is the ADS S, equipment designed for spraying solids. The model was redesigned to be more compact, responding to a direct request from producers, who were looking for more agility and versatility, especially on terrain with contour lines and areas that are difficult to access.

The S line is completed by the new ASP S, a machine designed for applying vinasse and liquid fertilizers, which now has a fiber tank, a material that reduces the total weight of the equipment and increases durability, without compromising application capacity and resistance in severe operating conditions.

The new generation of the S Series stands out in its 15 improvements. One of the most significant is the reduction in the turning diameter, which went from 27.3 meters to 17 meters. This represents a reduction of up to 60% in the maneuvering radius, directly impacting harvesting efficiency by reducing sugarcane trampling on the line and providing greater operational fluidity.

Another improvement is the balanced distribution of the load, resulting in greater equipment stability and longer tire life. The transshipment load lifting system has also been redesigned, ensuring greater space and less interference in the cargo box, reducing the accumulation of sugarcane residue.

In addition to the new machines, the company is launching the Mercedes-Benz Consortium at Agrishow . “The consortium offers a safe and planned alternative for those who want to modernize their fleet with innovative and high-performance Smart Machines, in addition to guaranteeing access to a specialized and nationally recognized technical support network,” says José Reche.

For the commercial director of the Mercedes-Benz Consortium , Claudio Jesus, the partnership with Grunner should revolutionize the agricultural market, offering financial solutions with no interest, no down payment and planning for the acquisition of agricultural machinery, which will boost the productivity and profitability of rural producers. “This strategic collaboration reinforces the commitment of the Mercedes-Benz Consortium together with Grunner to provide innovative and sustainable solutions to our customers, promoting an even more prosperous future for Brazilian agriculture”, emphasizes Jesus.

During Agrishow, Grunner presents its new after-sales service structure, with actions that reinforce the importance of preventive care with Smart Machines , ensuring not only operational efficiency, but also the safety and longevity of the equipment.

Among the new features are the launch of the after-sales area on the Grunner website to facilitate access to services and information for customers; the introduction of the maintenance contract to offer a predictable and preventive way of maintaining equipment; the performance of scheduled reviews in the off-season with the aim of avoiding interruptions during use; and the launch of the Grunner National Parts Consortium in the after-sales area to expand product availability and technical support throughout Brazil.

With eight contracts signed and 21 new service points starting from the 25-26 harvest, Grunner 's after-sales network is expanding with Mercedes-Benz dealerships as partners.

After three years of negotiations, Grunner achieved significant progress, thanks to the volume of purchases and the growing presence of its equipment in the field. Michelin nationalized the production of the tire used in the S line, previously produced in France, which increased costs due to imports. Developed with cutting-edge technology, the tire is exclusive to the S line and was designed to withstand heavy loads and offer high traction performance.

“For Grunner, establishing a partnership with a company like Michelin confirms that we are on a path of growth and building a promising future,” celebrates the company’s Commercial and Operations Director.

More than just incorporating cutting-edge technology, Grunner places the producer at the center of the innovation process. All new models launched at Agrishow were developed based on feedback from the field, collected from partners and customers who face the challenges of mechanized operations on a daily basis.

“Our purpose is clear: to deliver machines to producers that really make a difference in their day-to-day farming. It’s not enough to be modern; they have to be functional, accessible, durable and sustainable. The S Series is the result of active listening, precision engineering and a genuine commitment to those who are in the field producing,” says José Reche.

“ Grunner ’s presence at Agrishow 2025 goes far beyond just displaying products. We are here to show how our Smart Machines have transformed mechanization in sugarcane farming. Today, the choice between Grunner models is no longer limited to replacing the conventional transport system, consisting of a tractor and a bulk carrier, but rather to maximizing productivity and reducing costs at a new level of mechanization,” emphasizes the director of Grunner.
