摘要： A sickle knife section is adapted to be used with existing sickle guards in connection with a harvester, mower or the like. The knife sections have concave cutting edges on opposite sides of a central plane that are circular, and the cutting edges are along a line that moves away from a central plane of the knife section from a leading end of the knife section to position where the concave cutting edges intersect side edges of the knife section.

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： A valve block mounting arrangement for mounting a valve block directly to the ports of a hydraulic motor. The inventive device includes a main body having a first bore, a second bore and a cartridge bore. The first bore and the second are substantially parallel to one another with the cartridge bore intersecting the parallel bores and designed for removably receiving a control cartridge. A first female coupler and a second female coupler are rotatably positioned within the bores for connecting to a pair of corresponding hydraulic hoses. A first male coupler and a second male coupler are rotatably positioned within the bores opposite of the female couplers for threadably securing to the first port and second port of a rear ported hydraulic motor. The female couplers are preferably connected to the male couplers thereby allowing an individual to apply a tool to the female couplers to rotate the male couplers into the ports of the hydraulic motor. O-rings are positioned about the female couplers and the male couplers for preventing passage of hydraulic fluid about the couplers during operation. A conventional O-ring is positioned about each of the male couplers for reducing the likelihood of leakage during operation. In an alternative embodiment, the female couplers are permanently secured within the bores while the male couplers include an extended portion for allowing a tool to manipulate for rotating the male couplers into the ports of the hydraulic motor. Once installed upon the hydraulic motor, the user may interchange the control cartridge depending upon the type of valve they desire to create. It can be appreciated that one or more of the present inventions can be attached to the female couplers in a stacked configuration.
