Yield Monitoring System for a Head-Feeding Combine
This paper introduces a yield-monitoring system that was developed for a head-feeding combine. If yield variations could be measured during harvesting, data could be used to evaluate management history and provide useful information for planning fertilizer applications and management for the following year. First, we studied the yield-monitoring system

Path-Following Control of a Head-Feeding Combine Robot
Abstract The study aims to apply an autonomous path-following control for a head-feeding combine robot. A real-time kinematic global positioning system (RTK-GPS) and a GPS compass are used as navigation sensors. These sensors provide the combine robot with the position and heading information required to steer along a target path. To control steering,

Vision-based uncut crop edge detection for automated guidance of head-feeding combine [PDF]
Abstract This study proposes a vision-based uncut crop edge detection method to be utilized as a part of an automated guidance system for a head-feeding combine harvester, which is widely used in Japan for the harvesting of rice and wheat. The proposed method removes the perspective effects of the acquired images by inverse perspective mapping and ...

Near-Infrared Spectrometer for a Head-Feeding Combine for Measuring Rice Protein Content
We have developed a near-infrared (NIR) spectrometer mountable on a head-feeding combine for measuring rice protein in real time while harvesting. The developed sensor employs reflectance optics instead of the more usual transmittance optics because (1) it operates under severe vibration and dust conditions; (2) it performs measurements in high ...

Study on Performance Improvement of a Head-Feeding Rice Combine for Foxtail Millet Harvesting
Purpose: The study was conducted to investigate the proper working conditions like the mesh size of the concave and the chaffer angle of the oscillating sieve, and the fan speed of the head-feeding rice combine for foxtail millet harvesting. Methods: The study aimed to determine the harvesting conditions for the rice combine harvester at a 0.5 m/s ...

Development of a Torque Measurement Device for a Head-feeding Combine Harvester Engine Output Shaft
A torque-measuring device for measuring the engine output shaft on head-feeding combine harvesters was developed to investigate engine working load, an essential element in studies of fuel consumption and exhaust gas emissions. On most head-feeding combine harvesters, a pulley is fastened to an engine flywheel without a shaft.

Abstract The automation of agricultural work is expected to solve several of Japan's agriculture problems and help farmers. It has now become necessary to maintain the sustainability of national agricultural production. Thus, we have been trying to develop a robotic combine harvester. While attempts have been made to develop robotic combine harvester
