手扶拖拉机下陡坡时,由于重力的影响,会越跑越快。当驱动轮的转速超过发动机传给它的转速时,即出现所谓的“反驱动”现象。此时,手扶拖拉机转向时,必须彩用“反向操作”。如何判断手扶拖拉机下坡时是否已发生“反驱动”而应采取“反向操作”呢? (1)看V带。出现“反驱动”时, Walking tractor under the steep slope, due to the influence of gravity, will run faster. The so-called “anti-drive” phenomenon occurs when the rotational speed of the drive wheel exceeds the rotational speed delivered by the engine to it. At this point, walking tractor steering, you must use color “reverse operation.” How to determine whether the downhill tractor has occurred when the “anti-drive” and should take “reverse operation”? (1) See V belt. When “anti-drive” appears,
