摘要： An improved cutter assembly for use with a header of an agricultural harvester is provided. The assembly includes a pair of oppositely directed knife blades or cutter bars and a center knife drive. A crank shaft drives both knife blades in linear reciprocating paths with no fore and aft movement. As a consequence, harmful fore and aft vibration is eliminated. The assembly is simple and durable in design, less susceptible to vibration-induced wear and tear, and comparatively simple to manufacture and repair.

摘要： The pivoting action sickle drive has a low profile allowing incorporation in or below a floor of a header of a plant cutting machine to allow passage of cut plant material thereabout. The drive includes a substantially flat rotatable input element, and a drive arm connected eccentric thereto for eccentric rotation along an epicyclical path. The arm extends to a connection with a pivot arm of a pivot element that connects to a knife arm that drives a sickle knife assembly, such that the pivot element, knife arm and knife assembly will be reciprocatingly driven by the eccentric rotation of the drive arm. A second drive can oppositely drive a second sickle knife assembly, such that opposite forces generated by the drives will cancel. The drives can be packaged in a forwardly tapered or curved enclosure, and the pivot elements can be correspondingly shaped to streamline the drives.

摘要： An agricultural harvester includes a chassis and a grain tank carried by the chassis. The grain tank includes a frame having an opening formed therethrough; a pair of tank cover sections movably associated with the frame such that the tank cover sections can switch between an open position and a covering position relative to the opening of the frame; and at least one actuator linked to at least one of the tank cover sections and configured to selectively provide a switching force. The agricultural harvester further includes a force assistor or a brake linked to one of the pair of tank cover sections and configured to apply an assist force or a braking force, respectively, to one of the pair of tank cover sections but not the other of the pair of tank cover sections.

摘要： A cam reel for use on a harvesting header that can be configured in both operating and transport positions is provided. The reel comprises a plurality of finger-bearing reel bats disposed evenly around the reel shaft, each rotatably attached through the distal ends of radial arms extending outwardly from the reel shaft. A cam disc is attached to the frame and engages each reel bat by a cam follower, to provide rotational movement of the reel bats relative to the radial arms, during rotation of the shaft in the operating position. The cam has at least one operating position, and a transport position in which the engaged reel bats will be pivoted into transport mode that substantially reduces the risk of damage to the fingers.

摘要： A drive arrangement for split sickle bar sections of a harvester having a long cutter bar such as a combine, swather, mower-conditioner or the like utilizes separate drives for each sickle bar section, and provides for synchronizing the movement of the sickle bar sections so that they reach the respective ends of the reciprocating path simultaneously. In one form series connected first and second hydraulic motors are used, and the first motor in the series connection is reduced in speed from that which would be obtained from the full flow of a pump, by passing a portion of the pump fluid flow to a flow line leading to the second motor, a bleed valve bleeds off a portion of the flow in the flow line to regulate the second motor speed and position to match the speed and position of the first motor in response to signals indicating the position of the sickle bar sections. The sickle bar sections are thus synchronized.

摘要： The center sickle overlap arrangement of a sickle type mower for a cutter bar that include a pair of sickles for reciprocating motion where each sickle is essentially half the length of the cutter bar for reduced forces and vibrations for high speed cutting. In the center, the sickle blades overlap at only guard and the blade of one sickle is inverted and co-operates with a top ledger surface of the associated guard so that both the blades are in proper shearing arrangement with the respective guard ledgers. Further the top ledger surface is adjustable to allow clearance adjustment to ensure tight clearance between all sickle cutting surfaces and guard ledgers. Further the arrangement ensures that all crop is cut between sickle sections and guard ledgers rather than between a pair of sections on the opposing sickles.

摘要： A shear capable of cutting weeds close to the ground, without cutting grass in the presence of the weeds, is described. The shear can be implemented as a battery operated hand held device or as a shear mounted on a lawn mower. The shear operates by maintaining a spacing between the blades such that the flexible grass will only be bent between the blades. Weeds which have a thicker and stiffer shaft than the grass will be cut, thus functioning as a selective mechanical herbicide.

摘要： This invention relates to an improvement in a reciprocating mower of the type wherein two longitudinal rows of juxtaposed cutting teeth are relatively reciprocated by impact blows received from a rotary impactor. In accordance with this invention, the rotary impactor constitutes a relatively massive fly wheel and impact rollers are mounted on the outer periphery of the fly wheel member. Each of the rows of cutting teeth is connected to an actuator bar, and the two actuator bars are respectively disposed in spaced parallel relationship surrounding the periphery of the fly wheel and thus contacted by the impact rollers during each revolution of the internal gear. In accordance with another embodiment of the invention, the same motor driving means is utilized to propel a fan which is connected by a suitable housing to remove by air draft vegetation cut by the cutting teeth from such teeth and deposit same in a suitable receptacle.
