1.拖拉机和其他农机应尽量停放在车库内,防止风吹、日晒、雨雪侵蚀和冰冻。2.彻底清洗滤清器、油底壳、变速器,避免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。由于普通润滑油的粘度随气温下降而增加,导致流动性变差,机件运动时摩擦阻力增大,会造成拖拉机启动困难,甚至烧瓦、抱轴等。因此, 1. Tractors and other farm machinery should be parked in the garage as much as possible to prevent wind, sun, rain and snow erosion and freezing. 2. Thoroughly clean the filter, oil pan, transmission, to avoid mixing 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, mechanical friction increases when the movement will cause difficult start tractor, and even burning tile, such as axle. therefore,
