摘要： A hydraulically operated variable length top guide coupling member for use in three point linkage couplings for attaching agricultural implements to farm tractors includes a cylinder and a main piston with piston rod carried for longitudinal movement within the cylinder to thereby vary the length of the coupling member. Articulation means are carried at one end of the cylinder and at the other end of the piston rod for connecting the coupling member between a tractor and an agricultural implement. A pair of hydraulic lines provide communication between a source of hydraulic fluid and cylinder spaces on opposite sides of the main piston. A one-way valve is located in the path of communication between each of the hydraulic lines and the respective cylinder spaces. A control piston is carried between the two one-way valves for controlling opening of the valves. Application of hydraulic pressure to one of the hydraulic lines will open its respective one-way valve to permit hydraulic fluid to flow into the cylinder space on one or the other side of the main piston. Hydraulic pressure also acts on the control piston causing it to open the other one-way valve and permit hydraulic fluid to flow out of the other cylinder space into the other hydraulic line. Hydraulic pressure acting on the main piston will thus cause it to move within the cylinder to vary the length of the coupling member. The capability for immobilizing the main piston within the cylinder to fix the length of the coupling member to a desired position is also provided.

摘要： An adjustable length upper guide member for the hitch attachment of a tractor has an outer tubular guide element within which is telescopingly positioned an inner guide element so as to be relatively displaceable thereto. A housing on the outer guide element has a pair of jaws pivotally mounted therein and the jaws each have first arms which are engageable with annular grooves on the inner guide element and second arms which form actuating cams facing each other. A lever has an eccentric portion within the housing and one side of the eccentric portion is engageable against the housing and the other side of the eccentric portion engageable with the actuating cams so that pivoting of the lever causes the eccentric portion to act upon the cams and pivot the jaws to a disengaged position.

摘要： A coupling device for making a driving connection between a power take-off shaft and a transmission shaft has a coupling hub mounted upon the power take-off shaft and a coupling drum which co-axially surrounds the coupling hub may be journalled upon the hub or attached to the tractor. A coupling sleeve on a power transmission shaft is detachably connected to the coupling hub by a quick release fastener means. The outer surface of the coupling drum has a pivot support upon which an actuating member is pivotally supported. The actuating member has one arm connected to the coupling sleeve and the other arm defines an operating lever such that pivoting of the operating lever will effect a relative axial movement of the coupling sleeve and the coupling hub.

摘要： A three point linkage for attaching a working machine to a vehicle includes two lower guide members, a substantially U-shaped coupling frame pivotally connected at its ends with the lower guide members, and an upper guide member supported by tension springs from the U-shaped coupling frame. A length adjusting device is carried by the upper guide member for longitudinally varying its length. The upper guide member can be secured in various adjusted length positions. A link is connected between the coupling frame and the length adjusting device for actuating the adjusting device to vary the length of the upper guide member upon the application of pressure to the coupling frame. A catch hook for connection to the working machine is carried at one end of the upper guide member and the hook can be locked and unlocked by movement of the coupling frame.

摘要： A coupling hook has a latch element extending from a pocket through a passage to block a coupling pin in the hook opening in the locked position. The latch element is arcuate and has opposed curvilinear surfaces one of which is engageable with a fulcrum in the vicinity of an opening in the pocket through which an actuating lever of the latch element extends. The other curvilinear surface is engageable with a fulcrum in the vicinity of the passage and has a notch engageable with a bolt in the pocket in the locked position of the latch element. The latch element may be displaced to a release position either by lifting and then pulling the actuating lever or by a coupling pin engaging the curved end of the latch element to urge the latch element to a released position.

摘要： A device with which mowed straw material is prepared, that is, broken up into fibers, in order to speed up the drying process. In order to create a compact device that effectively prepares the straw material, there is an aggregate 3 provided with a central roll 5, to which there are assigned planetary rolls 6, 7 arranged around part of the outer circumference and rotating in the opposing direction, and the straw material is led into the clearance zone between the planetary rolls 6, 7 and the central roll 5. In order to improve preparation, the central roll 5, as well as the planetary rolls 6, 7, are provided with a surface structure matched to one another. The aggregate 3 comprises all components necessary for preparation and can be pre-assembled and installed in a grass-matting machine in vibration-isolated fashion via the elastic support 20.
