Traveling gear for agricultural working machine

A travelling gear for an agricultural working machine with control of the travelling speed when running on roads with a diesel engine as the central source of motive power, a variable displacement pump and at least one hydraulic motor, in which the delivery volume of the variable displacement pump and hence the travelling speed when running on the road is dependent upon the current position of an accelerator pedal, and the travelling gear consist of a variable displacement pump adjustable as regards its delivery volume, connected so as to be driven by the diesel engine, an electro-hydraulic motor with adjustable induction volume and two electro-hydraulic motors with switchable induction volumes, characterised in that, the speed of the diesel engine is controllable via an electronic accelerator pedal and the change in speed is measured electronically with a speed sensor and the delivery volume of the variable displacement pump is increased or diminished according to the measured speed.
