Abstract
A method for determining an axle load on a vehicle axle of a tractor includes providing a power lift and a payload coupled thereto, driving the power lift by a hydraulic pump, setting a pump pressure of the hydraulic pump as a function of the coupled payload, detecting the pump pressure by a sensor, and determining the axle load as a function of the detected pump pressure from characteristic data which represents a relationship between the pump pressure and the weight of the payload.

A method for determining an axle load on a vehicle axle of a tractor, comprising:
- providing a power lift and a payload coupled thereto;
- driving the power lift by a hydraulic pump;
- setting a pump pressure of the hydraulic pump as a function of the coupled payload;
- detecting the pump pressure by a sensor;
- and
- determining the axle load as a function of the detected pump pressure from characteristic data which represents a relationship between the pump pressure and the weight of the payload.

- setting a pump pressure of the hydraulic pump as a function of the coupled payload;
- detecting the pump pressure by a sensor;
- and
- determining the axle load as a function of the detected pump pressure;
- wherein, the axle load of the payload is determined from characteristic data which represents a relationship between the pump pressure and the weight of the payload;
- wherein, the pump pressure is detected when the hydraulic consumers of the tractor are switched off;
- and
- wherein, the payload is coupled as an attachment or as a ballast weight to the power lift.
