    • A mower assembly in which a standard sickle guard having two long fingers is replaced with a guard having two long fingers and two alternate fingers that are relatively short. The sickle blade cooperates with cutting surfaces on both the long and the short fingers. In the case of the long fingers, there are slots through which the sickle bar moves. In the case of the short fingers, the blade merely moves over a cutting surface of the short finger. There are trash bars extending between the fingers to strengthen the fingers and guard against rocks or uncut plants jamming the space between the fingers.The guard unit is fastened at two points to the guard support bar so as to minimize any tendency of the guard unit to turn.
    • 一种割草机组件,其中具有两个长指状物的标准镰刀保护器被具有两个长指状物和两个相对短的两个替代手指的保护器代替。 镰刃与长指和短指的切割面配合。 在长指的情况下,有镰刀杆移动的槽。 在短指的情况下,刀片仅在短指的切割表面上移动。 手指之间延伸有垃圾桶,以加强手指,防止岩石或未切割的植物堵住手指之间的空间。 防护单元在两点处固定到防护支撑杆上,以尽量减少防护装置转动的任何趋势。
