    • A sickle drive (62A, 62B) incorporated into a generally flat package or enclosure (64) or floor (28). The drive (62A, 62B) includes an epicyclic mechanism, including a rotatable input element (82) in an upper region of a cavity (78) of the enclosure (64), and an eccentric element (86) below the input element (82) rotatable eccentrically thereby. A drive arm (92) is connected to the eccentric element (86) for rotation about, and eccentric rotation with, the eccentric element (86), and extends to a pivot element (102) which can be the only component extending upwardly from the enclosure (64) or floor (28), such that the shaft (100) will be pivoted by the eccentric movement of the drive arm (92). A knife arm (76) connects to the pivot element (102) and a sickle knife assembly (58) which will be reciprocated by the pivoting action. A second epicyclic arrangement can be employed such that opposite forces generated by operation of the drive (62A, 62B) will be largely canceled.
    • 并入大体平坦的包装或外壳(64)或地板(28)中的镰刀驱动器(62A,62B)。 驱动器(62A,62B)包括行星齿轮机构,其包括在外壳(64)的空腔(78)的上部区域中的可旋转的输入元件(82)和位于输入元件(82)下方的偏心元件 )可旋转偏心。 驱动臂(92)连接到偏心元件(86),用于与偏心元件(86)一起旋转和偏心旋转,并且延伸到枢轴元件(102),枢轴元件(102)可以是从 外壳(64)或地板(28),使得轴(100)将由驱动臂(92)的偏心运动枢转。 刀臂(76)连接到枢转元件(102)和通过枢转动作往复运动的镰刀组件(58)。 可以使用第二行星架构,使得由驱动器(62A,62B)的操作产生的相反的力将被大大地消除。
