    摘要： A crop harvesting header with a cutter bar and a draper assembly has a draper canvas driven by a drive roller with a cylindrical roller body having an outer surface surrounding an axis of rotation of the roller for engaging an inner drive surface of a canvas wrapped therearound. The roller has a plurality of ribs arranged on the outer surface of the roller body extending along a part of the body in an axial direction and angularly spaced around the outer surface. The ribs have a height less than 6 mm and a width less than 6 mm arranged such that the ribs do not engage into any recesses in the drive surface of the canvas.

    摘要： An improved cutter blade or disc mower blade is provided having structure to reduce the tendency of vegetation to slip off and around the blade edge and tip. The disc mower blade is attached to a rotary cutter module and driven by a mowing machine. In one aspect of the disc mower blade, the disc mower blade includes a knife edge with serrations distributed along the edge such that vegetation does not slide along the edge during operation of the mowing machine. Further, another aspect of the mower blade is that the knife edge may be curved so as to prevent the vegetation from sliding along the edge during operation of the mowing machine. In another aspect, the disc mower blade includes a winglet disposed at a tip of the blade such that vegetation cannot slide past the blade during operation of the mowing machine.

    摘要翻译： 提供了一种改进的切割刀片或圆盘割草机刀片，其具有减少植被从叶片边缘和尖端滑落的趋势的结构。 盘式割草机刀片安装在旋转刀具模块上，由割草机驱动。 在盘式割草机叶片的一个方面，盘式割草机刀片包括具有沿着边缘分布的锯齿的刀刃，使得在割草机的操作期间植被不沿边缘滑动。 此外，割草机叶片的另一方面是刀刃可以是弯曲的，以便在割草机的操作期间防止植被沿着边缘滑动。 在另一方面，盘式割草机叶片包括设置在叶片尖端处的小翼，使得植物在割草机的操作期间不能滑过叶片。

    摘要： A sickle bar assembly is provided including a sickle bar for mounting a plurality of sickle cutting sections along a length of the sickle bar. The sickle bar has a first bar surface and a second bar surface. A bar thickness is defined between the first bar surface and the second bar surface. A plurality of bar apertures extend through the first and second bar surfaces and are arranged to facilitate mounting of the sickle cutting sections. The first bar surface includes a non-flat surface region comprising a plurality of indentations formed therein.
