Overhaul of the Bosch Rexroth electronic module for electrohydraulic management of the rear lift, with precise control of position and draft of attached implements
Details
The EHR-B control unit OE 87654386 is an original CNH electronic unit for New Holland, Case IH and Steyr tractors. Manufactured by Bosch Rexroth, it manages the electronic lift (Electronic Draft Control) and the vehicle's electrohydraulic functions. It operates at 12 V, controlling valves and sensors to regulate the implement's position, draft and depth with precise and safe movements. Integrated with the transmission and PTO, it ensures reliability, comfort and productivity.
Typical Errors and Defects
Typical faults:
Total absence of lifter movement
Irregular or jerky movements of the lifter
Difficulty maintaining the set height or effort (DRAFT)
Indicator lights illuminated on the instrument panel
Techinical Info
The control unit with OE code 0538201041 is an electronic CNH unit used on New Holland vehicles (also applied on Case IH and Steyr) for controlling the lift and some electro-hydraulic vehicle functions such as the cutting attachment on forage harvesters and combines. It is an EHR-D device (Elektronische Hubwerksregelung / Electronic Draft Control), i.e. electronic lift control, developed on a Bosch Rexroth basis, which automatically and proportionally manages lift movements and integrates control logic with transmission and chassis.
The module is housed in a casing installed in a protected area of the tractor, connected via sealed multipole connectors to the vehicle wiring, to hydraulic valves and to dedicated sensors.
Technical characteristics:
- Electronics manufacturer: Bosch Rexroth (EHR-D family for mobile hydraulics).
- Die-cast aluminum enclosure with mounting brackets and sealed multipole connectors.
- Internal architecture with microcontroller, analog and digital inputs, power drivers for controlling proportional and on/off valves.
- Inputs from lift position sensors, load/draft sensors, hydraulic pressure sensors and user controls.
- Outputs to the lift solenoid valves and to related auxiliary hydraulic circuits.
DIPA can intervene to overhaul these components thanks to its experience and expertise.
Functions:
- Electronic control of the lift (Electronic Draft Control) in position, draft (force) and mixed modes.
- Automatic management of working height and implement depth based on signals from draft and position sensors.
- Regulation of lowering speed and lift travel limits via parameters set by the operator.
- Control of the lift electro-hydraulic valves to achieve smooth, precise and repeatable movements.
- Management of external controls to the lift.
Model applications:
- New Holland TF/TX/FX (forage harvesters and combines)
Typical faults:
- Complete lack of lift movement
- Irregular or jerky lift movements
- Difficulty maintaining the set height or draft
- Warning lights illuminated on the instrument panel
Final conclusions:
The EHR-D New Holland 0538201041 control unit is a key component of the electro-hydraulic system on New Holland machines. It coordinates electronic lift control and connected cutting accessories such as forage harvesters and combines, ensuring work precision, comfort and safety.
