A system configured to couple an implement to a work vehicle includes a first lock assembly coupled to an arm of the work vehicle, and the first lock assembly includes a first lock, a second lock, and a first actuator configured to drive the first lock and the second lock laterally outwardly to engage respective first openings formed in the implement. The system also includes a second lock assembly coupled to a frame of the work vehicle, and the second lock assembly includes a third lock, a fourth lock, and a second actuator configured to drive the third lock and the fourth lock laterally outwardly to engage respective second openings formed in the implement.

The present invention relates to a working vehicle attachment tower which comprises a front loader mounting body and a supporting body. The front loader mounting body and the supporting body are manufactured as separate parts and welded to each other by at least one weld seam. The supporting body is manufactured by use of a massive forming process. Furthermore, the invention relates to a set of a plurality of working vehicle attachment towers and a method for manufacturing a working vehicle attachment tower.

A loader for a work vehicle includes a loader arm, a mast section rotatably connected to the loader arm, an implement removably attached to the loader arm, a first actuator connected between the loader arm and the mast, a second actuator connected between the loader arm and the implement, and a first roller apparatus having a use position and a storage position. The first roller apparatus is positioned nearer a ground surface in the use position than in the storage position. The first roller apparatus is in contact with the ground surface in the use position and spaced apart from the ground surface in the storage position.

An attachment system for a work vehicle implement includes an implement attachment assembly. The implement attachment assembly includes a support structure coupled to a receiver assembly. The support structure includes a first mounting feature configured to engage a first corresponding mounting feature extending downwardly from a bottom surface of a work vehicle, and a second mounting feature configured to engage a second corresponding mounting feature extending downwardly from the bottom surface of the work vehicle. The first and second mounting features of the support structure are spaced apart from one another along a longitudinal axis relative to a direction of travel of the work vehicle, and the first and second mounting features of the support structure are configured to substantially block horizontal and vertical movement of the support structure relative to the work vehicle via engagement with the first and second corresponding mounting features of the work vehicle.

Components of a jig are suppressed from coming into contact with a pin hole when a coupling pin is removed from the pin hole, and a length of the jig in a coupling pin axial direction is held down. A coupling pin attaching/detaching apparatus (a coupling pin extracting apparatus) includes a cylinder and a connection member. The cylinder is arranged outside a coupling pin in a radial direction of the coupling pin and is extensible. The connection member is connected to the coupling pin and the cylinder. Extension of the cylinder causes the coupling pin to be extracted from a pin hole via the connection member.

A front loader includes a link operating mechanism spanning a bucket and a stand. The link operating mechanism is configured to cause, using a swing force of the bucket, a bending and stretching link to bend so that propping and supporting of the bending and stretching link are released.

A front loader comprises an arm, a work implement supported to a tip portion of the arm, and an angle display device. The angle display device includes a gauge member, an indicator, a shaft member, and a conversion mechanism. The gauge member has a scale indicating an angle of the work implement relative to the arm. The indicator is movable relative to the gauge member according to variations of the angle of the work implement. The shaft member is movable along the arm according to variations of the angle of the work implement. The conversion mechanism changes a relative position of the gauge member and the indicator according to the movement of the shaft member. The conversion mechanism is configured so as to cause the indicator to rotate relative to the gauge member around a rotation axis being parallel to an axis of the shaft member in one direction or another direction according to the movement of the shaft member.
