In the rain and snow weather, agricultural machinery operators must pay attention to the following matters when operating agricultural vehicles:
First, the road surface is covered with a layer of thin ice, which reduces the friction coefficient between the tire and the road surface and greatly reduces the adhesion. The driving wheel is easy to skid or idling, especially when going uphill, starting and parking. Phenomenon; If the vehicle suddenly accelerates or decelerates during driving, it is easy to cause side slip and direction deviation; in case of emergency braking, the braking distance will be greatly extended, more than 4 times higher than normal dry road. Therefore, in this case, the key to driving is “slow motionâ€: the throttle should not be too large, the brakes should not be used, the direction should not be too large, and the clutch should not be lifted too fast. If necessary, add a tire chain to the tire.
Second, if there is a phenomenon of wheel slip at the start, a gear that is one level higher than usual can be engaged. The clutch is loosened more slowly than usual, and the magnitude of the adjustment of the transmission force is best resolved by the magnitude of the semi-clutch. The throttle is smaller than usual, as long as the engine does not stall. Once the wheel has turned, immediately switch to a lower gear, you can normally refueling.
Third, because the braking distance will increase with the increase of the vehicle speed, controlling the vehicle speed and maintaining a large safety distance from the preceding vehicle is the key to driving on ice and snow roads. If the vehicle speed is too fast, the safety distance between the two vehicles is small. Once an emergency situation is encountered, the consequences will be unimaginable.
Fourth, when you need to turn, you must first decelerate, increase the radius of the turn and slowly hit the steering wheel. Hold the steering wheel with both hands to smooth the movement, otherwise it will happen to slip.
5. Whether it is giving yourself or giving someone more distance when driving, don't scramble for the lane. Always maintain a sufficient safety distance with the vehicle in front, and experience deceleration in advance. When you find a brake in front of the vehicle, you should immediately take off the oil and prepare your feet on the brake pedal.
Sixth, must not slam on the brakes, that will likely cause a side slip. If there is a side slip, the brake should be released immediately to allow the steering wheel to regain control of the vehicle. Take brake measures before entering the turn, and do not step on the brakes in the curve. In that case, inertia will cause the vehicle to lose control.
7. During the journey, in addition to diligently observing the road conditions ahead and the rear-view mirror, we must also be aware of the cars on both sides and in front of us so that we can make judgments earlier. Try not to change lanes as often as possible. If it is necessary to change lanes, turn on the turn signal first, then see the condition of the road surface in the rearview mirror and change the line after confirming safety.
8. After the engine is turned off, all the water in the engine should be released to avoid freezing the engine.
