Abstract

A device for the control and adjustment of hydraulic cylinders on work attachments and assemblies of work machines, preferably self-propelled harvesting machines. Increasing the performance of harvesting machines for bringing in crops efficiently and without loss requires rapid, uncomplicated adaptation of the harvesting machines and front harvesting attachments to the respective load and operating conditions. The front harvesting attachments and wheel carriages are connected to the hydraulic circuit of the harvesting machine and driven automatically by means of the electronic control system as a function of the respective working and operating conditions.
