农机具的推广应用大大减轻了劳动强度,但由于诸如交通、资金及自然条件的影响,目前尚有一部分地方不适用较大型的联合收割机作业,而使用可以代替人工割麦的单用途收割机(有叫割晒机或叫推推的)。这种机型有一个不可克服的问题,就是需要有一条摆放割下的麦子的行道。目前这种行道一般在收割前 The popularization and application of agricultural machinery has greatly reduced the labor intensity. However, due to such factors as traffic, capital and natural conditions, there are still some places that are not suitable for larger combine harvesters. Instead, single-purpose harvesters that can replace artificial cuttings are used (Called windrower or pushing). One of the insurmountable problems with this model is the need for a walkway for the cut wheat. The current road is generally before harvesting
