Development and evaluation of forage yield measure sensors in a mowing-conditioning machine

Original language description

The main aim of this research was to develop and evaluate sensor system to create forage yield maps on a three-point linkage type of rotary mower-conditioner. The method was based on the mowing machine conditioner's power requirement measured by a torquesensor or on material change in momentum measured by a curved impact plate. Laboratory measurements were taken to determine the dependence of conditioner power input and signals from the impact plate on material mass flow. A mixture of grass and alfalfawas used. There was a very good linear relationship between the conditioner's power, impact force from an impact plate, and material feed rate through the mower. The calculated coefficients of determination (R2) were about 0.95. It was possible to differentiate a material feed rate difference 0.5 kg s&#8722;1 using either method. The effects of material changes and mower parameters on the accuracy of feed rate measurement were then measured. It was observed that the results form torque
