A universal, mobile, backhoe system integrated with a vehicle and related methods are disclosed. An example embodiment includes: a boom; an arm coupled to the boom; an implement coupled to the arm; a swing mount coupled to the boom, the swing mount including a pivot point; a truck mount removably coupled to the swing mount; stabilizer legs coupled to the truck mount, the truck mount further including a mounting bracket removably coupled thereto and configured to be removably attached to a hitch receiver of a vehicle, the truck mount further including mounting shafts removably coupled thereto and configured to be removably attached to at least two points of a bed of the truck.

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.

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 loader attachment system is configured so as to detachably attach a loader to a vehicle by detachably attaching a mast of the loader to a loader mount fixed on the vehicle. The loader attachment system includes a support device, a location device, and an engagement device. The support device is configured to support the mast on the loader mount so that the mast is rotatable relative to the loader mount. The location device is configured to locate the mast supported on the loader mount by the support device at an attachment position. The engagement device is configured to engage the mast at the attachment position with the loader mount so as to prevent the mast from rotating in a direction to detach the mast from the loader mount. The support device, the location device and the engagement device are configured independent of one another.

A front loader includes a boom, a main frame attached to a vehicle body, a sub frame supporting the boom and being detachably attached to the main frame. The front loader includes a receiving tool provided on the main frame a cylindrical shaft provided on the sub frame and configured to be engaged with the receiving tool when attaching the sub frame to the main frame, a protruding portion protruding from the main frame and configured to guide the cylindrical shaft to be engaged with the receiving tool, and a coupling plate provided on the sub frame, the coupling plate having an opening through which the protruding portion is inserted when the cylindrical shaft is engaged with the receiving tool. The protruding portion protrudes forward from the main frame in a front-rear direction of the vehicle body.

An automatically actuated shunt valve system opens and closes a passage between two chambers of a powered element operated by a power source. The shunt valve system includes a coupler connecting the powered element with the power source through two mating coupling elements. One of the coupling elements includes a valve contact and the other includes a shunt valve assembly. The shunt valve assembly includes a valve chamber connected with both chambers of the powered element, a valve element opening or closing a flow path between the conduits, and a shaft for moving the valve element. The shaft engages the valve contact to move the valve element to close the flow path when the coupling elements are mated together, and moves the valve element to open the flow path when the shaft disengages from the valve contact as the coupling elements are disconnected from one another.

A front loader includes a boom, a main frame attached to a vehicle body, a sub frame supporting the boom and being detachably attached to the main frame. The front loader includes a receiving tool provided on the main frame a cylindrical shaft provided on the sub frame and configured to be engaged with the receiving tool when attaching the sub frame to the main frame, a protruding portion protruding from the main frame and configured to guide the cylindrical shaft to be engaged with the receiving tool, and a coupling plate provided on the sub frame, the coupling plate having an opening through which the protruding portion is inserted when the cylindrical shaft is engaged with the receiving tool. The protruding portion protrudes forward from the main frame in a front-rear direction of the vehicle body.

A front loader includes a boom, a main frame attached to a vehicle body, and a sub frame supporting the boom. The sub frame is attached to the main frame and configured to be detached from the main frame. The front loader includes a first engaging portion provided on the main frame, a second engaging portion provided on the sub frame and configured to be engaged with the first engaging portion when the sub frame is attached to the main frame, a guide portion provided on the main frame and configured to guide the second engaging portion to be engaged with the first engaging portion, and an opening member provided on the sub frame and provided with an opening portion to which the guide portion is inserted when the second engaging portion is engaged with the first engaging portion.

A loader for a tractor includes a loader arm, a parking support, and a lock brace. The parking support includes a support pivot end pivotally coupled to the loader arm, a ground engagement end opposite the support pivot end, and a plurality of connection regions disposed between the support pivot end and the ground engagement end. At least one connection region of the plurality of connection regions includes an obstruction. The lock brace includes a brace pivot end pivotally coupled to the loader arm and an attachment end opposite the brace pivot end. The attachment end is made to removably couple to any of the connection regions. The obstruction obstructs coupling of the attachment end of the lock brace to the respective connection region of the parking support.

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.
