Patent Images
1. An agricultural working machine, comprising:
- a tire pressure control system (26) for inflating and deflating a tire (14) to control an air pressure level of the tire such that during street operation the tire air pressure is at a street pressure level and during field operation the tire air pressure is at a field pressure level that is reduced compared to the street pressure level; and
a device for adjusting a ground speed, wherein a maximum ground speed (v) of the agricultural working machine (2) is determined as a function of the tire air pressure of the tire (14) using a tire air pressure sensor (33) in the tire, andwherein a maximum driveable ground speed (v) that depends on the tire air pressure is preselectable for different tire sizes, for different tire types or both.
