摘要： A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less.

摘要： A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of independent teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less.

摘要： A stump remover for cutting and grinding tree stumps and roots comprising a rectangular-shape housing which serves to support and contain the various elements of the stump remover. At the aft end of the housing is mounted a power source, preferably an internal combustion engine, which provides rotational energy to the cutting assembly at the fore end of the housing. The cutting assembly comprises a drive shaft which is mounted within the housing at an angle of approximately 61 degrees relative to the top of the housing. The end of the shaft is provided with four radially extending and equally spaced carbide teeth. Each of the teeth includes a bent portion which forms an angle of approximately 45 degrees with the axis of the drive shaft. For the transmission of rotational energy from the power source to the cutting assembly, preferably a cog V-belt is provided. The aft end of the housing further includes a wheel assembly which is mounted slightly behind the center of gravity of the power source so as to cause the housing to rotate forward bringing the cutting assembly in contact with the ground. To assist a user in overcoming the tendency of the housing to tip or rotate forward and allow the user to control the cutting depth, the aft end of the housing further includes a footrest and a handle bar assembly.

摘要翻译： 用于切割和研磨树桩和根的树桩去除器，包括用于支撑和容纳残端移除器的各种元件的矩形壳体。 在壳体的后端安装有动力源，优选内燃机，其在壳体的前端向切割组件提供旋转能量。 切割组件包括驱动轴，该驱动轴相对于壳体的顶部以大约61度的角度安装在壳体内。 轴的端部设置有四个径向延伸且等间隔的硬质合金齿。 每个齿包括与驱动轴的轴线形成大约45度的角度的弯曲部分。 为了将旋转能量从动力源传递到切割组件，优选地提供齿轮V形带。 壳体的后端还包括轮组件，该轮组件稍微安装在动力源的重心之后，以使壳体向前旋转，使切割组件与地面接触。 为了帮助用户克服外壳倾斜或向前旋转的趋势，并允许使用者控制切割深度，壳体的后端还包括搁脚板和手柄组件。

摘要： A cylindrical device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of the cylindrical device or rotor. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less. The knives may have sharpened edges that are oriented to cut on different planes as the cylindrical device rotates. The knives may be held in place by holders that have configurations to oriented the knives at certain angles.

摘要： A land clearing attachment for a tractor device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of a rotor. Each tooth, knife, or blade is part of a row of independent teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less. The spiral or helical orientation of the cutting teeth, knives, or blades enables the power to be reduced typically required to effectively rotate a similarly sized rotor.
