Drive and Control Systems for Combine Harvesters and Forage Harvesters Electro-Hydraulic Header Control EMR Active damping of header vibration while driving: prevents machine becoming uncontrollable while driving on public roads, permits higher driving speeds, relieves the driver, more comfortable driving, greater safety Header is controlled in the preset position: for harvesting tall crops (maize), pitching movement is reduced by active vibration compensation, detection of ground contact to prevent damage to the header Header is controlled at the preset height: for harvesting short crops, pitching movement is reduced by active vibration compensation, detection of ground contact to prevent damage to the header, transverse slope compensation of the header (optional) Header controlled to ensure constant ground pressure: for harvesting laid crops, main weight of table is borne by the lifting hydraulics (little friction, prevents “fretting“, transverse slope compensation of the header (optional) Control valve EHR5 or EHR5LS-OBE Single-acting flanged valve for header control Optionally available with onboard electronics for CAN communication during operation and diagnosis Control valve EHR23LS or EHR23LS-OBE Single-acting flanged valve for header control (higher flow) With onboard electronics for CAN communication during operation and diagnosis Electronic control unit EMR Position control / clearance control Ground pressure control Vibration compensation System diagnosis Inductive position sensor, Inductive angle sensor and Pressure sensor Relevant links to Combine Harvesters and Forage Harvesters: Combine Harvester Forage Harvester Hydrostatic Drive Transmission Implement Hydraulics Electronic Drive Management Components Applications Center Agricultural Machines Back to Combine Harvesters and Forage Harvesters Home Page
