Silver Awards at Agritechnica (Part 1)

Published on: 14:41PM Nov 10, 2009

Every Agritechnica, the top innovations introduced at the event receive a gold or silver medal.


Here is the first wave of silver medal winners for 2009, and check back for more coverage from the upcoming event. The DLG (German Agricultural Society) reports more than 1,850 exhibitors from 40 countries have booked stands at Agritechnica. This exhibition for agricultural machinery will take place in Hanover, Germany through Nov. 14.

CNH: Automatic fan speed setting in sloping terrain


Customary slope compensation systems for combine cleaning only react to lateral inclination. If a combine harvests in the rise and fall line, during uphill work this can lead to blowing over of grain and non-grain constituents from the cleaning unit and hence to elevated grain losses. During downhill travel the layer thickness on the screens increases and higher quantities of non-grain constituents enter the grain tank; if the layer thickness is too high this also leads to higher grain losses. The speed control of the New Holland cleaning blower independently of the slope gradient is the first to adjust the blower speed automatically to the respective combine inclination in uphill and downhill work depending on the crop. This allows uniform work quality and work output during harvesting on sloping fields without the driver having to intervene, thus facilitating work, and is a trail-blazing detail improvement in grain crop harvesting.

CNH: Gentle on the soil and relieves the burden on the driver

New Holland's ABS system offers not only the generally known safety benefits but also caters to the specific demands of agriculture. For instance it allows the popular individual wheel braking and correspondingly small turning radius during headland operations for the first time. The inner wheel in the bend is delayed specifically in proportion to the steering angle without causing any blockage with damage to the track. The system also serves as a starting aid on hillsides, is gentle on the soil and relieves the burden on the driver.

Pottinger: Automatic knife grinding system for loader wagons

Grinding knives on loader wagons has so far been known as time consuming and non-ergonomic work. Pottinger has succeeded in developing an automatic grinding machine for individual knives in loader wagon cutter units. The automated grinding operation can be carried out several times a day during transport. The complete hydraulic drive is designed simply and maintenance-kindly. Constantly sharp knives with a high cutting quality for efficient performance of work are now possible on loader wagons too.

Pottinger: Intelligent Loader Wagon Combination (together with John Deere)
Pottinger uses the new opportunities offered with the "intelligent loader wagon" that if necessary not only stops the tractor, but also steers the speed of travel of the combination depending on the windrow density. The windrow form is determined with ultrasonic sensors mounted at the front of the tractor. As the data are collected ahead, the tractor has sufficient time to respond and adapt its speed. The system not only has a target value for speed, but also controls acceleration. It operates in combination with a sophisticated sensor system on the loader wagon at all relevant speeds of travel and improves the efficiency of the overall process, at the same time distinctly relieving the burden on the operator.

Krampe: Bandit roller belt wagon

Loading and unloading of this body trailer are carried out via a fabric belt that is wound up alternately by hydromotors mounted one at the front and one at the rear end of the cargo platform, thus moving the cargo. The advantage of this design over a push-off wagon is the higher payload and lower hydraulic power requirement. Delicate goods like potatoes can be unloaded gently, and pallets and general cargo can be set against the tail flap and carried forward for loading. 


: Belarus 3023 220 kW standard tractor

The 220 kW standard tractor has a diesel-electric drive with modern control electronics and good efficiency levels. The front PTO is powered electrically and its rpm speed is thus largely independent of the internal combustion engine. Up to 172 kW electric power can be passed on from the internal DC high voltage network to external users that display corresponding power requirements.

Hagele: Cleanfix Pulstronic

The fan vanes on the Cleanfix Pulstronic can be turned about the longitudinal axis not only to clean the radiator, but also to save drive energy. Depending on cooling requirements the vanes can be positioned in any intermediate position. This allows a control circuit that processes PWM or CAN bus signals of the engine controller and regulates the exact vane position via a position sensor to be integrated in the adjustment mechanism. By contrast with the visco-coupling there is no power consuming coupling slip, regardless of the fan output. In addition the "Flex Tips" fitted at the vane ends are slightly oversized so that they are ground into shape in operation in the front area of the cowl. This effectively avoids air recirculation and additionally enhances efficiency.

Krone: Front mower EasyCut 32 CV Float

Pushed headstock with integrated spring weight alleviation and novel spring balancing kinematics provide uniform ground pressure under all operating conditions. The EasyCut 32 CV Float is the first front mower with pushed headstock and integrated mower weight alleviation that at the same time allows uniform ground pressure to be maintained through the novel "Float" spring balancing kinematics. Accordingly the advantages of the "pushed" front mower are combined with those of the "trailed" mower without applying any additional load on the front axle as has been necessary so far with other header designs, representing advantages above all on sloping terrain. The extra benefit of the uniform ground pressure is unique.

Krone: VariStream

Variable crop flow system in self-propelled forage harvester reduces resistance material flow to cut wear, saves energy and relieves the engine. In the Krone VariStream system the front part of the drum base is hinged to the shearbar. When the shearbar is adjusted after grinding of the knives, the drum base in the front area automatically follows. There is thus no "dead space" between the shearbar and drum base that could impair the flow of crop negatively. The rear part of the drum base is mounted on springs and can thus yield under large quantities of feed. At low crop flows, the base returns to the original position thanks to the springs. The risk of clogging is lower, a uniform crop flow is retained and the ejection performance of the chopper drum is not reduced.
