摘要： A mower cutting unit is provided with a rear-mounted grass catcher. The cutting unit includes front and rear rollers and mounted between the rear roller and the grass catcher is a rotary brush. The brush is mounted for adjustment into and away from engagement with the rear roller and for adjustment into and away from engagement with the turf. The brush may be driven either in the same direction as or counter to the direction of rotation of the rear roller during forward mowing operation. When driven counter to the direction as the rear roller, the brush may either be positioned for only cleaning clippings from the rear roller and depositing them into the grass catcher or be positioned for additionally sweeping the turf. When the brush is driven in the same direction of rotation as the rear roller, it operates, depending on its positional relationship to the rear roller and turf, to either only clean the rear roller, to clean the rear roller while sweeping the turf to disperse clippings or to just sweep the turf to disperse clippings.

摘要翻译： 割草机切割单元设置有后置安装的抓地器。 切割单元包括前辊和后辊，并且安装在后辊和牵引器之间是旋转刷。 刷子被安装用于调节和远离与后辊的接合，并且用于调节和远离与草皮的接合。 在正向割草操作期间，刷可以在与后辊的旋转方向相同的方向上驱动。 当与后滚筒相反的方向被驱动时，刷子可以被定位成仅用于清洁来自后滚筒的剪切并将它们放置在草地捕捉器中或者定位成用于额外地扫掠草皮。 当刷子沿着与后辊相同的旋转方向被驱动时，它根据其与后辊和草皮的位置关系而操作，以便仅清洁后辊，以清洁后辊，同时扫过草皮以分散 剪报或只是扫过草皮散散。
