    • A tree saw attachment (10) for use with a loader vehicle includes a base frame (11), a generally V-shaped blade assembly (12), a brush guard (13), and a tweezer arm assembly (14). A swingable tweezer arm (29) of the tweezer arm assembly is movable using a hydraulic cylinder (33) to grasp objects against an upper surface of the base frame or the blade assembly. The brush guard and tweezer arm assembly are removable from the base frame as a single unit to facilitate shipping and assembly. A sprayer assembly (90) is positioned within the base frame for applying a herbicide to tree stumps cut by the V-shaped blade assembly. The blade assembly can be a single integral blade (42), or can be formed of right and left blades (70, 71) with intermeshing projections (73, 74) secured to a rib member (36) along a centerline of the blade assembly.
    • 一种与装载机车辆一起使用的树锯附件(10)包括基座框架(11),大致V形的叶片组件(12),刷子防护件(13)和镊子臂组件(14)。 镊子组件的可摆动的镊子臂(29)可使用液压缸(33)移动,以将物体抵靠在基座或刀片组件的上表面上。 刷子护罩和镊子臂组件可作为单个单元从基座框架移除,以便于运输和组装。 喷雾器组件(90)定位在基座框架内,用于将除草剂施加到由V形叶片组件切割的树桩上。 刀片组件可以是单个整体刀片(42),或者可以由右刀片和左刀片(70,71)形成,其中啮合突起(73,74)沿着刀片组件的中心线固定到肋构件(36) 。

    • The spike wheels of the harrow are arranged in gangs to rotate about a common axis during ground engagement. Each wheel has a plurality of spikes that project outwardly from a cylindrical hub having a pair of opposite ends. Projections at one end of the hub are matingly received within notches in the opposite end of the hub of the next adjacent wheel so that the wheels are interlocked for rotation in unison. The projections on each hub are offset angularly from the notches by a certain amount so that adjacent wheels are correspondingly rotatively offset from one another. The outermost tips of the spikes of each wheel are intumed to a certain extent so as to render each wheel generally concavo-convex, with the concave sides of the wheels leading as the machine is pulled through the field. Front gangs of the wheels are disposed in a certain oblique attitude with respect to the path of travel of the machine, while rear gangs are disposed in opposite oblique attitudes.
    • 在地面接合期间,耙子的穗轮布置成帮助围绕公共轴线旋转。 每个轮具有从具有一对相对端的圆柱形轮毂向外突出的多个钉。 在毂的一端的突出部分配合地接收在下一相邻轮毂的相对端的切口内,使得轮互锁以一致地旋转。 每个轮毂上的突起与凹口角度偏移一定量,使得相邻的轮相应地相互旋转地偏移。 每个轮的尖峰的最外端的尖端被一定程度地拉近,以使得每个轮通常是凹凸的,当机器的凹面被引导通过该领域时。 车轮的前方组合相对于机器的行进路径以一定的倾斜姿态设置,而后部组合以相反的倾斜姿态设置。
