“…Similar results, that the shearing stress decreased as the cutting height increased, were reported for sunflower (İnce et al, 2005), safflower (Özbek et al, 2009), wheat (Tavakoli, et al, 2009), and selected biomass (Yu et al, 2014). Esehaghbeygi et al (2009) and Koloor (2007) showed that an oblique angle of 30° was sufficient to reduce the shearing stress of paddy and wheat stems. With this research, it was found that an oblique angle of 30° was sufficient to reduce the shearing stress of sainfoin stem.…”

“…The cutting force and energy are affected by plant factors, the knife blade design, and operation mode and knife angles (Ghahraei et al, 2011). Koloor (2007) found that the lowest specific cutting energy values for paddy stem were provided with a bevel angle and oblique angle of 28° and 30°, respectively. Liu et al (2012) reported that a serrated blade required less cutting force and cutting energy than those of a flat blade for cutting Miscanthus stem.…”

IntroductionField crops are defined as any of the herbaceous plants grown on a large scale in cultivated fields, primarily grains, forage, sugar, oil, or fiber crops that are used as raw material by various branches of industry (Zia-Ul-Haq et al., 2014;Ahmad et al., 2015;Cesur et al., 2018).Sainfoin (Onobrychis viciifolia) is a perennial, deeprooted, drought-resistant, common forage legume. It is a good source for animal feeding, veterinary, soil improvement, and bee pollen and nectar. It ranks third among forage legumes after alfalfa and cow vetches, with acreage of 193,694 ha, and had a production of 1,982,047 tons in Turkey in 2016 (TÜİK, 2017). Information about the physical and mechanical properties of the plants is necessary in the design and development of machines such as choppers, mowers, harrows, and balers. Methods and procedures for determining the mechanical and rheological properties of agricultural products were described by Mohsenin (1980). Several studies have been conducted to determine the mechanical properties of plants. The bending and shearing properties of the stem or stalk of plants, together with the modulus elasticity when bending, are important mechanical properties for the design of cutting or chopping units. These mechanical properties vary depending on the species, variety, climatic conditions, stalk diameter, plant stem height, moisture content, cellular structure, and maturity. Many studies have been carried out to determine the mechanical properties of plant stems, such as sorghum (Cattopadhyay

“…Increase in cutting angle from 25˚to 35˚resulted in a slight increase in force and energy. The increase of cutting angle resulted in an increased area of cut thereby making greater blade travel leading to slightly higher cutting energy consumption as reported by Tabatabaee- Koloor (2007). Increase of cutting velocity decreased the penetration time during cutting process and thus lowered the cutting energy.…”

“…Furthermore, operational parameters of the cutting blade like bevel angle, blade orientation, and cutting speed have been shown to be vital in energy efficient crop cutting performance (Allameh & Alizadeh, 2016; Arzola & García, 2015; Dauda et al., 2015; Eliçin et al., 2019; Ghaffari et al., 2020; Hou et al., 2020; Mathanker et al., 2015; Maughan et al., 2014; Modak & Raheman, 2022; Nuţu et al., 2012; Sushilendra et al., 2016; Y. Wang et al., 2020; C. Zhang et al., 2019). Using the proper blade parameters also reduces the energy consumption during crop stem cutting (J. N. Chen et al., 2018; Ding et al., 2015; Jyoti et al., 2021; Koloor & Kiani, 2007; O'dogherty & Gale, 1991a; O'dogherty & Gale, 1991b; Sahoo & Raheman, 2020; Tabatabaee‐Koloor et al., 2004; Tabatabaee‐Koloor, 2007). Therefore, to optimally design a harvesting system with a better understanding of cutting mechanics, a device is needed that can be used to study different parameters related to cutting energy.…”

A device was developed for on‐field cutting energy measurement of cereal crops. Physical, engineering, and anatomical properties of prominent rice (Oryza sativa L.) cultivars of India were studied at different stem positions using a factorial CRD design. The effects of changes in different operational parameters, including blade bevel angle (15°, 20°, and 25°), cutting angle (25°, 30°, and 35°) and cutting velocity (2.9, 3.44, and 4.1 m s−1) on cutting force and cutting energy of rice stalk were also studied. Cutting angle indicated the angle of inclination of cutting edge to the horizontal at blade‐crop interface. The assessment of these properties and parameters in relation to crop cutting energy, led to the development of a smart device for energy measurement up to a size of three skills. This device consisted of a compression system, crop holding unit, cutting unit, and sensors to measure the force, speed, and cutting height. The device's measurement abilities were evaluated with wheat (Triticum aestivum L.) stalks at different cutting speeds (0.83, 1.16, and 1.5 m s−1 and stem heights (10, 20, and 30 cm from ground). Values for cutting force and energy ranged from 1.85 to 1.45 N and 10.81 to 8.48 N mm–1, respectively. At all stem heights, the cutting force and cutting energy ranged from 1.79 to 1.44 N and 11.92 to 6.74 N mm–1, respectively. The ultrasonic sensor provided real time cutting height data with an accuracy of 97.5%, while the gyroscope sensor had an accuracy of 94.29% for on‐field cutting angle measurement.
