Crop Elevator and Combine Harvester

A combine harvester comprising a crop elevator comprising:

• an ascending section and a descending section;
• a housing enclosing the ascending section and the descending section;
• an elevator loop arranged inside the housing and comprising a plurality of paddles for elevating a harvested crop;
• and
• a weighing system configured to determine a weight of the harvested crop that is present on a measurement paddle of the plurality of paddles during an ascending movement of the measurement paddle in the ascending section, the weighing system comprising a weight sensor that is mechanically coupled to the measurement paddle and is configured to output a weight signal representative of the weight of the harvested crop,
• wherein the ascending section comprises a measurement section,
• wherein the weighing system is configured to determine the weight signal when the measurement paddle is in the measurement section of the ascending section, and
• wherein a friction between the measurement paddle and the housing in the measurement section is lower than a friction between paddles and the housing outside the measurement section, during the ascending movement of the measurement paddle in the ascending section.
