目前,东风12型和15型手扶拖拉机在农村中普遍使用。手拖进行农田作业、犁地、旋耕、开沟等选用多大的作业速度呢?应根据耕地土壤类别、地表状况、土壤含水量、农艺要求以及拖拉机发动机功率消耗、负荷能力等因素来确定。在选择农田作业速度时,要保证农田作业质量,又要提高拖拉机作业效率。现根据多年来的实践经验,介绍手拖农田作业速度的选择方法,以供参考。
Currently, Dongfeng 12 and 15 walking tractors are commonly used in rural areas. How much work speed should be selected for farmland operations, plowing, rotary furrowing and ditching should be determined according to the types of cultivated soils, surface conditions, soil moisture content, agronomic requirements, tractor engine power consumption, load capacity and other factors. In choosing farmland operating speed, it is necessary to ensure the quality of farmland operations, but also to improve tractor operating efficiency. Now based on years of practical experience, the introduction of hand-picked farmland operating speed selection method for reference.
