我认为东方红—75与铁牛—55A拖拉机起动方法从理论上讲是一样的,只是操作方法不同而已。东方红—75拖拉机在起动起动机之前,先接合上自动分离器齿轮,在分离离合器的情况下起动起动机。而铁牛—55A型拖拉机起动之后,在分离离合器的情况下,接合自动分离器齿轮。二者都使自动分离齿轮处在静止状态(因为没有动力传递)时与静止的飞轮齿图相啮合,这样容易啮合上。否则一个静止、一个动,是接 I think Dongfanghong-75 and Tractor-55A tractor start-up method in theory is the same, but different methods of operation only. Dongfanghong -75 tractor before starting the starter, the first engagement of the automatic separator gear, the clutch in the case of starting the starter. After the Trent-55A tractor is started, the automatic separator gear is engaged with the clutch disengaged. Both make the automatic separation gear at rest (because there is no power transmission) and stationary flywheel gear meshing, so easy to engage. Otherwise a static, a move, is to pick
