Driving winter farm machinery is most afraid of rain and snow and fog. To ensure safety, tractor drivers should be reminded to pay attention to the following points:
1. Strictly prevent locomotive skidding and side slip: The tractor runs on snow and thin ice. Because the friction between the tire and the road surface is very small, the walking steering mechanism is prone to skidding and accidents. At this time, driving the tractor must be slow, you can not rush the steering wheel, but also to avoid changing the gear, or easily out of control. If you are walking on a slope, the speed of travel is even slower. Use a second-speed, small throttle to avoid skidding. When the tractor must cross the snowdrift, it should be passed vertically against the snowdrift, and should not be passed on both sides of the snowpile to prevent skidding and accidents. If the wheel is caught in the snow and the pit is too deep, do not force it through so as not to become deeper and deeper. At this time, the surrounding snow should be cleared before passing, thereby avoiding the car.
2. Strictly prevent the occurrence of slope accidents: When driving on the slope, it is easy to slip and cause a crash. Therefore, it is forbidden to use a neutral slope to slide downhill. At this time, the engine speed and the appropriate gear must be used to control the speed, and the brakes cannot be braked to limit the driving speed of the tractor. It is necessary to select appropriate gears in advance and do not shift gears in the middle. Do not use the slope method to upgrade the slope to prevent accidents when the slope is uphill. When the tractor appears to be sliding, it should be turned to the sideslip side immediately instead of to the opposite direction. Steering direction, otherwise the side slip will be more serious, at this time can not interrupt the oil supply or clutch separation; if the brake caused by the side slip, to immediately stop the brake to eliminate the side slip; if the crawler tractor side slip, can be used to separate a corresponding The side power is used to control the skid, but it must not be eliminated by braking, otherwise a more serious side slip or an accident may occur.
3, prevent snow breakdown: As the weather is cold, the snow melts, just thawed muddy road slippery, do not rush to hit the steering wheel, otherwise the mud will often accumulate mud on the wheel will trap the tire or track, causing it to break, and great resistance . At this point, the attached mud and snow should be removed at any time. If you start to slip on a thawed road, you should remove sand and slag on the floor to eliminate slipping. In addition, the tire pressure should be reduced, plus weight; crawler tractors can loosen the track.
