Innovative extensions for more functionality

More than 35 years of experience stand behind the Electrohydraulic Hitch Control EHC from Bosch Rexroth. It forms the solid basis for the continual advancement of this global success story. Innovative expansions adapt the EHC to the various needs of our customers.

 

Double works better – Double Acting Hitch Control EHC-da


Gentle working of the soil, increased efficiency, and ease of use characterize the double-acting version of the EHC. Active, regulated compression allows the EHC-da to reach the desired working depth faster and optimizes depth control – even in hard soils and changing ground conditions. In addition, the EHC-da allows the hitch gear to be quickly and easily lowered, even when the hydraulic oil is cold, and enables attachments to be easily decoupled.

Clever adjustment – Automatic Hitch Control AHC


The AHC software module automatically and dynamically regulates the ratio between position and tractive force.

In this way, the hitch control adjusts perfectly to different soil conditions. To achieve optimum results, only the required working depth has to be set. Individual settings remain possible in manual mode.

Tracking the ground perfectly – Pressure Relief Control PRC


With the hydraulic Pressure Relief Control PRC, the front hitch gear follows the ground contours even more precisely to ensure that both the soil and the attachment are handled gently. The operator can make the setting conveniently from the cab, for either manual or automatic tracking. Furthermore, PRC simplifies the coupling of attachments like a mower, since the usual relief springs are no longer needed. PRC needs no pressure sensors or accumulator, thereby saving space and costs.

Lowering fast and gently – Hitch Lowering Support HLS


Simple to integrate, simple to use: HLS provides pressure to the hitch gear to lower it actively and thereby significantly faster.

The advantages are realized especially when the hitch gear has no load and when ambient temperatures are low. The limited pressure also means attachments can be unhitched more easily – especially useful when catch hooks become jammed.
