Abstract

To control the hydrostatic transmission (7) of a cross country machine, for agriculture or forestry, during slow driving the motor speed is limited and is proportional to the speed command from the driver but slower than the normal driving speed. The diesel motor (1) drives a pump (8) for a hydraulic motor (9) connected to the wheels (13) through a gearbox (10) and differential axle (12).
