1拖拉机和其他农机应尽量停放在车库内,防止被风吹、日晒、雨雪侵蚀和冰冻。2彻底清洗滤清器、油底壳、变速器,否则会造成不同牌号的润滑油混存,降低润滑效果。3及时更换润滑油。由于普通润滑油的黏度随气温下降而增加,导致流动性变差,因而机件运动时摩擦阻力增大,拖拉机启动时经常导致冷启动困难,甚至产生燃瓦、抱轴等事故。因此,在冬季来临时,应及时将油底壳、空压机和轮毂轴承内的润滑油换成冬季用的润滑油;将变速器、分动器、差速
1 tractors and other farm machinery should be parked in the garage as far as possible to prevent the wind, sun, rain and snow erosion and freezing. 2 Thoroughly clean the filter, oil sump, transmission, otherwise it will result in the mixing of different grades of lubricant, reducing the lubrication effect. 3 timely replacement of lubricants. As the viscosity of ordinary lubricating oil increases with the temperature drop, resulting in poor fluidity, thus increasing the frictional resistance of the machine movement, the tractor often leads to cold start-up difficulties, and even burning shingles, axles and other accidents. Therefore, in the winter approaching, the oil pan, air compressor and wheel hub bearings should be replaced by lubricants in winter lubricants; the transmission, the transfer case, differential
