近年来,农业机械化发展突飞猛进。特别是拖拉机、联合收割机,国产的、进口的,大马力、集成化,种类繁多,层出不穷。其安全运行的保障条件和安全操作的要求差异性较大。根据农业机械结构性能和安全运行技术条件的不同,对拖拉机、联合收割机机型进行科学分类,有针对性地制定相应的登记管理制度,实行精准管理,显得十分必要。一、当曹的笼统分类模式亟待改变目前,拖拉机、联合收割机登记类型分为大中型(功率大于等于14.7千瓦)、小型方向盘式、手扶式拖拉机和方向盘自走式、操纵杆自
In recent years, the development of agricultural mechanization by leaps and bounds. In particular, tractors, combine harvesters, domestic, imported, high-powered, integrated, a wide variety, an endless stream. The safe operation of the security conditions and safety requirements of the larger differences. According to the different performance of agricultural machinery and safe operation of the technical conditions, the tractor, combine harvester models for scientific classification, targeted to develop the corresponding registration management system, the implementation of precision management, it is very necessary. First, when Cao’s general classification model needs to be changed At present, the registration types of tractors and combine harvesters are divided into large and medium-sized (with a power of 14.7 kilowatts or more), small steering wheel, walk-behind tractor and steering wheel self-propelled,
