A readily attaching-detaching structure of a front loader that can make the attaching and detaching work to a vehicle body easier, a front loader, and a work vehicle. The attaching-detaching structure of a front loader is provided with a first retained member that is on either a main frame on a vehicle body or a sub-frame that supports a boom; a second retained member on the other of the main frame or the sub-frame; a first retaining member that retains the first retained member and is on the side opposite of the first retained member; a second retaining member that retains the second retained member and is on the side opposite to the second retained member; a first guiding member that guides the first retained member to the first retaining member when the sub-frame is mounted on the main frame; and a second guiding member that guides the second retained member to the second retaining member when the sub-frame is mounted on the main frame.

A conversion kit for converting a front-loader bucket for use as a forklift, a bale transporter or similar object mover. Parallel tine assemblies pivoted to a bucket top include tines that normally project forwardly, and cooperating vertical arms linked to the tines. The arms are fastened at their bottoms within protective elbow brackets to which the tines are pinned. The arms support hollow pivot sleeves penetrated by axle members that enable tine assembly rotation. A plurality of box-like receivers forming sockets enable the quick connection and/or disconnection of parts. Lower receiver sockets removably support pivot sleeves secured to quick-connect plugs that are penetrated by axle segments. A pair of rigid, tine stowage brackets may be secured at the rear. After the projecting tines are unpinned from front mounted elbow brackets, the tine assembly may rotate over the bucket to an out-of-the way position.

The invention relates to a front loader (10) comprising: at least one fastening arrangement (12) connectable to a working vehicle (1); at least one loader arm (20) with a first part (21) and a second part (22) connected via a knee section (23), the first part (21) being pivotally connected to the fastening arrangement (12) at a pivot point (P1); a tool attachment (14) device connected to the second part (22) of the at least one loader arm (20); at least one tilting cylinder (16) connected to the tool attachment device (14) and to a knee link (30) arranged at the knee section (23), wherein the knee link (30) comprises a first attachment point (31) for connection with the tilting cylinder (16), a second attachment point (32) for connection with the loader arm (20), and a third attachment point (33) for connection to a mechanical self-levelling device (50), wherein the knee link (30) is arranged at the knee section (23), such that the first attachment point (31) is essentially aligned with or below an upper end (24) of the first part (21) of the loader arm (20).

The invention relates to an agricultural device for semi-automatic movement of a holding tool, for holding an object, between two positions, said two positions being at different heights. The device comprises said holding tool for holding the object, load sensing means for determining if the holding tool holds an object, driving means (9) for moving the holding tool up and down, a control unit for controlling the driving means, and a user interface for user input to the control unit. The device can be used in two modes of operations, wherein the holding tool in a first mode of operation is freely movably, and in a second mode of operation is semi-automatically movable between a plurality of determined positions (URP, UPP, LRP, LPP) depending on if the holding tool is holding an object or not, and which command is given to the user interface. The invention further relates to an agricultural vehicle comprising such an agricultural device, a method for an agricultural device, for such semi-automatic movement, and software for obtaining information related to driving means, said software being adapted to perform the method according to the invention.

The attaching-detaching structure of a front loader is provided with a first retained member that is on either a main frame on a vehicle body or a sub-frame that supports a boom; a second retained member on the other of the main frame or the sub-frame; a first retaining member that retains the first retained member and is on the side opposite of the first retained member; a second retaining member that retains the second retained member and is on the side opposite to the second retained member; a first guiding member that guides the first retained member to the first retaining member when the sub-frame is mounted on the main frame; and a second guiding member that guides the second retained member to the second retaining member when the sub-frame is mounted on the main frame.

An attaching-detaching structure of a front loader that can make the attaching and detaching work to a vehicle body easier, a front loader, and a work vehicle. The attaching-detaching structure of a front loader is provided with a thumb which, on a sub-frame that supports a boom, is supported so as to be able to move between an engagement position for engaging with a main frame provided on a vehicle body and a release position at which engagement with the main frame is released, and which is biased in the release direction toward the release position from the engagement position; and a lock bar which, on the sub-frame, is supported so as to be able to move between a regulated position for regulating movement of the thumb in the release direction from the engagement position, and a regulation release position that allows the thumb to move to the release position.

A zero-turn mower including a removably attached front-end loader, where front-end loader includes two boom arms and a bucket, and an attachment mechanism. The attachment mechanism may include a center plate, a loader attachment mechanism, and a mower attachment mechanism.

A gripper for an implement for handling bales includes a body having at least one support arm, at least one tine coupled to the body, and a cutting device. The at least one tine protrudes in a direction beyond the cutting device in at least one region.

Disclosed are hay bale spikes for tractors used to carry hay bales. A hay bale carrying system includes a frame attachable to a tractor. The frame includes a first spike rigidly connected and a second spike movably attached parallel to the first spike, where the second spike is movable to a position that is not parallel to the first spike. An opening in the frame may position a pin to matingly accept the second spike that includes a lever arm on the opposite side of the pin from the spike. The lever arm may include a connector near its end connectable to a hydraulic cylinder such that expansion and contraction of the hydraulic cylinder provides leverage through the pin to the second spike to move the second spike from a first parallel position relative to the first spike to a second non-parallel position.
