摘要： The compact sickle drive mechanism is adapted to incorporated into or beneath a floor or pan of a header at a location between and spaced from the sides or ends of the header, and can be configured for reciprocatingly driving two knife assemblies disposed in end to end relation, in opposite directions, such that potentially vibratory forces, including those generated by the moving masses of the knife assemblies, at least substantially cancel one another and thus are not transferred to structure of the header. As a result, the overall width of the header and structure thereof can also be reduced.
摘要翻译：紧凑型镰刀驱动机构适于在头部的侧面或端部之间和间隔开的位置处并入头部的底板或盘底部或底部，并且可以构造成用于往复驱动两端设置的两个刀组件使得潜在的振动力（包括由刀组件的移动质量产生的振动力）至少基本上相互抵消，因此不会转移到集管的结构。结果，头部的整体宽度及其结构也可以减小。

摘要： The present invention relates to a mulching rotary lawn mower blade and a method of mulching grass using a mulching rotary lawn mower blade. The mulching rotary lawn mower blade comprises a mounting section adapted to be attached to a lawn mower motor drive shaft and first and second sections extending respectively further outward from the mounting section and being respectively pitched upwardly and downwardly. First and second cutting surfaces are formed along at least a portion of at least one of the first and second surfaces. The first cutting surface is adapted to form grass clippings, while the second cutting surface has at least one cutout and is adapted to cut the grass clippings. The first cutting surface passes the grass clippings to the second cutting surface which recuts the grass clippings as the grass clippings pass through the cutout.

摘要： Controlled gap thin blade shear process to cut grass using a low energy sickle mower. A thin dull blade moves without interference across a stator. Blades and stators are not biased or pressed together while cutting, but rather the cutting blade is guidingly supported by upper and lower stators formed and positioned to maintain forceably a total controlled gap (Z) therebetween of preferably 1-5 mils. The cutting blade is thin (10-50 mils). Tensile failure of grass is avoided. Torque management system performs motor load monitoring and modulation of blade position. To reject obstructions and clean the blade, the blade can reverse, jitter, or reciprocate. Instead of attempting to slice or slam through obstructions using a high torque prime mover, a low energy low torque prime mover is utilized with intelligent reversing, obstruction clearing, and blade cleaning that saves energy, reduces noise, rejects obstructions, and prevents blade damage or operator injury.
摘要翻译：使用低能量镰刀割草机控制间隙薄叶片剪切过程切割草。薄的钝的刀片在定子上没有干扰地移动。叶片和定子在切割时不被偏压或压在一起，而是切割刀片由形成和定位的上定子和下定子引导支撑，以在其间保持优选1-5密耳的总控制间隙（Z）。切割刀片很薄（10-50密耳）。避免了草的拉伸失效。扭矩管理系统执行电机负载监控和刀片位置调整。为了排除障碍物并清洁刀片，刀片可以反转，抖动或往复运动。而不是试图用高扭矩原动机切割或撞击障碍物，低能量低扭矩原动机被用于智能换向，障碍物清除和刀片清洁，从而节省能量，减少噪音，排除障碍物并防止刀片损坏或操作人员受伤。

摘要： A power-operated sickle for cutting agricultural plants and for preventing the cut stalk of the plant from coming in contact with reciprocating components of the sickle. The sickle includes a plurality of cutting teeth attached to a drive bar that is slidably retained on a stationary horizontally disposed sickle bar. A plurality of underside teeth are attached to the sickle bar and extend forwardly therefrom. A cover member is attached to the sickle bar and extends over covering the drive bar and other reciprocating components thereat. The cover member includes a plurality of upper teeth that extend over the underside teeth and sandwich the reciprocating cutting teeth therebetween. The cover member includes a semi-circular section extending between its attachment to the sickle bar and the upper teeth. The gap between the upper and underside teeth is selectively adjustable for a proper setting during initial assembly and for, thereafter, adjusting for wear of the cutting teeth, upper teeth, and underside teeth.

摘要： A two-piece cutter member for mounting on a sickle bar has a rigid thin support element arranged for relatively permanent attachment to a sickle bar, and a flat planar pyramid-shaped spring metal blade. A portion of the blade provides at least one bridge or loop for encircling the support element and holding the blade on the support element. A section of either said the portion or the support element is displaced with respect to the support face to releasably hold the blade on the support when the blade is fully positioned on said support element.

摘要： Hinged tables for swathers usually are provided with individual knife sections and the center section of this knife is difficult to drive. This invention eliminates the necessity for a center section drive by using a two section knife on a three section table with each knife section extending through one wing section and part of the center section. The knives are driven from the outer ends and are allowed to flex over the hinge area. The wing sections are provided with rigid guard bars and a flexible section of guard bars secured to the inner end of the rigid guard bar and is secured by the other end to the center of the center section by means of a swivel or sliding connection.
