A self-leveling front-end loader for attachment to a tractor. The self-leveling front-end loader includes a support structure configured to be attached to the tractor, and two extendable booms, each boom including a proximal leg, a distal leg, and a self-leveling hydraulic linkage configured to maintain the tilt angle of an accessory, such as a bucket. Each extendable boom has a boom extension hydraulic cylinder for extending the boom by up to 2 to 4 feet, a lift hydraulic cylinder to lift each boom, a self-leveling hydraulic cylinder, and a tilt hydraulic cylinder to tilt the accessory. The extendable booms enhance the capability of the front-end loader to position payload higher and farther than a standard front end loader, while preserving the stability and lifting capacity of the front-end loader. The booms have a traditional dogleg bend of 105 to 135 degrees, providing the two booms a wide range of motion.

A stand of a front loader includes: a main body that is disposed on a boom and swings between a supporting position in which the main body supports a front loader and a storage position in which the main body is stored; a grounding-member swing shaft that is disposed on the main body and engages with the boom to hold the main body in the storage position; a swinging member swingably disposed on the boom; and an engagement lever disposed on the swinging member, wherein the main body has a guiding hole that guides the engagement lever to regulate a swinging range of the main body.

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.

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.

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.

To provide a 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 support for and/or a front loader includes a first main frame fixed to one of a left and right side of a vehicle body and a second main frame fixed to the other of the left and right sides of the vehicle body. A rear end of the second main frame is positioned further forward than a rear end of the first main frame.
