摘要： A working machine coupler device includes a top linkage, a lower linkage, a detachable frame including a second upper coupler to be coupled to a first upper coupler, and a second lower coupler to be coupled to a first lower coupler, and a top linkage controller. The second upper coupler is coupled to the first upper coupler when the lower linkage is pivoted upward, and the first lower coupler moves toward and be coupled to the second lower coupler when a front portion of the working machine is moved upward, and the top linkage controller regulates the stretching and shortening of the top linkage to hold the detachable frame inclining backward, and allows the top linkage to be shortened until the working machine takes a working posture after the lower linkage is pivoted downward from a state where the front portion of the working machine is lifted.

摘要： A connector for use in as a third point connector for a tractor has a hydraulic and pneumatic chamber for providing an easy method to adjust the length of the third point connector to thereby change the angle between the tractor and an attached implement. When a release valve is opened, the two sides of the connector can be moved towards or away from each other as air enters from the environment or exits as needed to balance the pressure inside the connector. An induced air pocket in the hydraulic chamber allows for a slight cushion against the forces as the incompressible hydraulic fluid prevents larger swings in the length of the connector. One or more of the opposing ends may have threaded connectors to allow for general size changes to the connector.

摘要： An extensible bar comprises a bar and a sleeve that slide over each other and are kept together by a pin. The extensible bar includes a locking system made up of a latch connected by a wire spring to the sleeve, the latch preventing sliding movement between the sleeve and the bar when the latch is positioned within respective recesses formed in the bar and in the sleeve when the recesses are aligned. The wire spring urges the latch into the recesses. Unlocking of the assembly entails pulling the latch out of the recesses by grasping and pulling a handle attached to the latch. The locking system can be blocked by turning the latch about the wire spring into an orientation that prevents the latch from entering the recesses. The locking, unlocking, and blocking functions are performed by an assembly of only three parts; the latch, the wire spring, and the handle.

摘要： The invention relates to a lower link assembly for a tractor hitch. The lower link assembly includes a first strut and a second strut. The first strut includes a channel at an end thereof and a hollow space defining first and second walls and adjacent to the channel. The second strut may be inserted into the channel. A locking element is associated with the hollow space for latching the second strut to the first strut, and may be moved between an unlocked position and a latching position. A spring pretensions the locking element in the latching position. A grip element is connected to the locking element, by means of which an operator may move the locking element into the unlocked position. The spring is biased to retain the locking element in the hollow space.

摘要： The invention refers to an extensible bar for tractors, comprised by a bar 1 and a sleeve 2 that slide over one another and are kept together by a pin 9 and including a locking system 3. The locking system is comprised by a latch 7 that prevents sliding movement between the sleeve 2 and the bar 1 when it is positioned within the housings of the bar and sleeve when they are aligned, by means of the actuation of a wire spring 6. The assembly is unlocked when the latch 7 is manually pulled out of the housings by means of a pull handle 8 directly attached to the latch. The locking system can be blocked to facilitate the detachment of the accessory, by turning the latch 7 about the wire spring 6, to prevent the latch 7 from engaging the housing. All these three functions: locking, unlocking and blocking of the system are performed by an assembly of only three parts 6, 7 and 8 of low production cost.
