Case IH introduces its system of automatic management of productivity in the high-end tractors

With the steady increase in the prices of energy, the tractor seeks ever more optimize the efficiency of their engines, reducing operating costs. To respond to these needs, Case IH now offers new technical features for tractors of series Magnum and Steiger Quadtrac, especially in terms of reduced consumption and, therefore, increase the efficiency of the tractors.

The APM is a management system fully integrated in the transmission, introduced for the first time in the market for tractors in 1998, with transmissions continuously variables of the CLC series.

For example, with this system, fuel consumption can be reduced to 24 per cent in the Magnum (with certain load conditions), to tractors of the same category without APM system. In comparison with the tractors with conventional transmission control, which must be constantly select the marches and the regime of the engine on the basis of the work situation, the APM of Case IH is responsible for the control of the regime and speeds.

The operator only has to operate a switch so that the system to take control. Switch informs the APM if the tractor is working in the field or is moving by road and connects with programmes suitable for different tasks. The mode of working both in the transport, the engine is reduced provided that the burden of the device allows it, thus automatically reducing fuel consumption and allowing the operator to focus on the work being performedinstead of having to be aware of the regime.

To maintain constant the speed of the TDF with powered attachments, the system is fixed. In the case of the Magnum, the speed of 1,000 rpm of the TDF is reached with an economic system of the engine, at 1,800 rpm.

In the mode of work, the APM controls the speed of progress desired, between 1 and 23 kilometers per hour, selected by the operator, and adjust the engine to maintain that speed with different loads and efficient consumption. In the mode of transport, the pedal and the throttle lever become operators speed controls. The more use the accelerator, faster will be passing the tractor between the speeds of the transmission of 1 to 40 kilometres per hour, i.e. that the APM will select the regime and the gear ratio suitable for the required forward speed.

The APM of Case IH has proven to be more effective co-ordinating the potency of an operator to manually control the engine and transmission. Regardless of if the tractor is moved by road with a trailer or works with tillage implements an irregular terrain, the control system will constantly making minor adjustments so that the tractor works always with maximum efficiency.

"The engine for tractors of higher performance that exists today"

The new 485 Steiger tractor will be presented with important innovations, as the 12.9 litre Iveco engine that is equipped with Turbo Compound technology. This system directs the exhaust gases to a second turbine situated behind the turboalimentador. The energy of the turbine transmitted direct power to the crankshaft through a set of reducers and a Voith hydraulic coupling, which considerably increases the power of the engine and reduces fuel consumption.

Using the same amount of fuel, the performance increases 8 percent. Thus, the 485 Steiger has a specific consumption less than 195 g/kWh, which makes it "one of the tractors of smaller consumption of the world".

Prepared for bio-diesel

All Steiger tractors are prepared to work with bio-diesel from the models of this new year. The use of 20 percent biodiesel (B20) is possible in all models, and biodiesel B100, 385, 435 and 485 models, provided they meet with the current specifications of Case IH.
