Forage Harvester

Harvesting performance up to 400 tons an hour, even when used 24 hours a day throughout the entire harvesting season.

High performance and availability of a unit is independent of its type of control. Whether mechanically, hydraulically or electrically actuated, all Linde controls operate with absolute precision and reliability.

Intelligent electronic controls offer an extended range of sophisticated comfort-, application- and safety features. The controls ensure that the diesel engine, variable-displacement pump,  and motor are perfectly matched to each other in every situation. Utilization of the installed power is optimized, and the fuel is used efficiently. The electronics themselves offer an impressively high level of safety – in both concept and design. If, however, external circumstances cause the control signals to fail, the hydraulic units set their swash plate angles back to minimum volume. The machine decelerates moderately until standstill, without over-revving the diesel engine.

The powerful Linde HMV 210-02 hydraulic motor enables speeds of up to 40 kph on the road. The harvesting gear covers a speed range up to 15 kph, which makes shifting gears unnecessary on the field. The optimum speed is pre-selected in each case, and is reliably maintained thanks to the automatic regulation; after turning round, it is rapidly regained.

A second hydraulic motor can be activated at the rear axle. The two units can be controlled independently of each other, and the axles are not mechanically coupled. The tractive effort is distributed to the front and rear axles to suit the situation so that the traction limit is reached on both axles simultaneously. The mechanical decoupling of the two axles protects the soil, even when driving in tight curves. Reducing the effective torque to zero ensures that the vehicle retains full steering properties at all times, even when decelerating sharply.
