This standard specifies the tests necessary to determine the usable power in the shaft of the rotating elements of motor-cultivators and motor-hoes, in the shaft of the driving wheels and in the output shaft of the independent power take-off. The nominal power test is used to define the power of the tiller or tiller. The nominal power must be determined by measurement carried out on the tool axis. In the event that, by design, all the engine power cannot be transmitted to this axle, the power measured on the drive wheel axle or on the independent power take-off shaft will be used.
