Increase crop yields with a system solution

Resists monsoons and dust storms even without a driver's cab: The EHC-8 system solution for tractors in emerging markets

Bosch Rexroth's electrohydraulic hitch control for tractors from 30 kW upward is adapted to climatic requirements in emerging markets

With the Electrohydraulic Hitch Control EHC-8, Rexroth has developed a system solution that meets the needs of emerging markets with tractors from 30 kW upward. It efficiently improves soil cultivation as the basis for higher crop yields and also increases driver safety. The components are adapted to the climatic conditions of tropical and subtropical regions such as India, Southeast Asia, Africa and South America.

Farmers can achieve sustainable yield increases with automated soil cultivation. By controlling the exact amount of force, the exact positioning or a mixture of both, the Electrohydraulic Hitch Control EHC-8 from Rexroth is able to perform precise lifting and lowering of the hitch and thus makes precise plowing possible. The earth is evenly and gently broken up, providing better yields. While this technology has long been a standard in the premium range and medium-sized tractors segment, purely mechanical solutions still prevail among the 30 to 90 kW tractors used in emerging markets. These tractors are prone to wear and the driver needs to turn around to operate and manually readjust them. He therefore has no view toward the front and has to put enormous strain on his back.

With the EHC-8 system solution, Bosch Rexroth is filling a gap in the market. The company has revised all of the system components and adapted them to the needs of the lower performance class. For instance, most tractors produced in and for emerging economies have no cab. As a result, the control panel for the Rexroth EHC-8 is also exposed to adverse environmental conditions, such as monsoons and high humidity, as well as heat and dust particles. What's more, the tractors usually have no suspension and therefore generate more vibrations. A weatherproof design and a cushioning support protect the control panel, which is located in the armrest. In addition, it has much more powerful lighting, making it legible even in intense sunlight.

Like its larger cousins, the Rexroth EHC-8 ensures more even soil cultivation in different soil conditions and reduces the slippage of the tractor wheels when tougher sections need to be overcome. The driver specifies the desired depth and can concentrate on driving. Furthermore, when it comes to transporting items with the plow raised or with other attachments, the system implements a damping function when driving on poorly constructed roads, thus avoiding unsafe driving conditions.

Bosch Rexroth has sold more than three million EHC units in all power output classes. In addition to the EHC-8, the EHC-15 covers the performance class up to 180 kW and the EHC-22 covers the premium class from 160 kW upward. The system solutions consist of mobile electronics adapted to one another in function and performance together with the appropriate software, as well as EHR series valves and sensors. Tractor manufacturers can fully integrate the electrohydraulic hitch control into their tractors' overall operating concept. What's more, the software can also be installed on a higher-level Rexroth SRC control unit for the entire tractor.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 29,500 associates generated sales revenue of approximately 5 billion euros in 2016.

Greater availability of agricultural and forestry machinery thanks to smart servicing

As part of the electronification of mobile hydraulics, Bosch Rexroth is developing new, data-based services for all aspects of mobile working machines. The PredictDrivetrain service from Bosch Rexroth detects wear using operating and sensor data and is able to determine the remaining service life. Thus, downtimes for tractors, combine harvesters and other agricultural and forestry machinery in the field can be avoided without the conventional, pre-scheduled preventive maintenance intervals. The lean determination of operating data also serves as a basis for the application-oriented design of mechanical components using the NextGenSpec app without the danger of undersizing or oversizing. For the assembly of new vehicles, CalibrateHydraulics significantly reduces the commissioning effort with the online transfer of test bench data for components to the OEM.

Next generation of mobile electronics is ready

At Agritechnica 2017, Bosch Rexroth will unveil the next generation of controllers for mobile working machines developed jointly with Bosch. It combines proven features, such as free programmability with a new hardware architecture and a future-proof software concept. Developed to meet more demanding system requirements, Bosch Rexroth is developing sensors with SENT interface at the same time, which in addition to all measured values also transmit condition data to the controller. The first controllers as well as the SENT sensors will go into series production as early as 2018.
