Two methods has been developed and tested for the measurement of the mowing machine material feed rate (based on the conditioner power input measured by a torque-meter, and/or on the material change in momentum measured by a curved impact plate). A very good linear relationship existed between the conditioner power input, output frequency of the apparatus measuring the impact force by means of the impact plate, and the material feed rate through the mowing machine. The calculated R-Squared values were about 0.95. The impacts of material and condition (parameters) changes on the feed rate measurement accuracy were measured under laboratory conditions. It was evident from teh statistical evaluation that changing crop variety, crop maturity, and intensity of conditioning have a statistically significant influence on teh measurement based on the torque-meter. As concerns the impact plate measurement, it was not possible to determine the influence of the factors tested.
