A front loader frame includes a first attachment having a first attachment surface that can be oriented on a first virtual plane and is fixable to one portion a vehicle body. A second attachment has a second attachment surface that can be oriented on a different virtual plane from the first virtual plane and is fixable to another portion of the vehicle body.

Disclosed is a cantilever, including: a spar connected rotatably about a rear fixed axis to a fastening device for a vehicle; a tool lever connected rotatably about a front fixed axis to the spar; a deflecting triangle connected rotatably about a central fixed axis to the spar; a rear strut connected rotatably about a first strut pivot axis to the fastening device and rotatably about a second strut pivot axis to the deflecting triangle; a front strut connected rotatably about a third strut pivot axis to the deflecting triangle and rotatably about a fourth strut pivot axis to the tool lever. The rear and the central fixed axis span a first plane, the rear strut intersects the first plane, the central and the front fixed axis span a second plane, and the front strut intersects the second plane.

A system for determining a position of a pin inserted within a pinhole of a work machine is disclosed. The system includes a follower, a sensor, and a controller. The follower is biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole. The sensor is configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole. The controller is configured to determine the position of the pin based on the state of the follower.

A manual locking subassembly for a loader system of a utility vehicle includes an actuator manually operable from an operator cab of the vehicle and a mechanical linkage extending from the actuator and affixed to a loader attachment carrier rotatable about an axis. Manipulation of the actuator in a first direction moves a linkage member of the mechanical linkage from a first position in which a loader attachment implement is uniformly movable with the attachment carrier to a second position in which the loader attachment implement is non-uniformly movable with the loader attachment carrier.

A machine is disclosed as having a body, and left and right traction devices supporting opposing sides of the body. The machine may also have a power source mounted to the body at a front end relative to a normal travel direction. The power source may be configured to drive the left and right traction devices. The machine may further have left and right lift arms. Each of the left and right lift arms may have a base end pivotally connected at a back end of the body to a location gravitationally above the left and right traction devices, respectively. The machine may additionally have a tool coupler mounted to distal ends of the left and right lift arms.

A tool system is disclosed for a machine. The tool system may have a first adapter configured to removably connect with a first side of the machine, and a second adapter configured to removably connect with a second side of the machine opposite the first side. The tool system may also have a frame member with a first end pivotally attached to the first adapter, and a second end pivotally attached to the second adapter. The tool system may further have a tool pivotally connected to the frame member between the first and second adapters, and at least one hydraulic actuator disposed between the frame member and each of the first and second adapters.

A method and apparatus assists coupling a loader with a work vehicle. A pre-position instruction signal is generated to pre-position the loader in a predetermined orientation to facilitate the coupling. A forward movement instruction signal is generated for initiating movement of the associated work vehicle 1 towards the loader. A coupled confirmation signal representative of the loader being coupled with the associated work vehicle is received. A forward movement pause instruction signal for pausing the movement of the associated work vehicle towards the loader is generated responsive to receiving the coupled confirmation signal. One or more of the pre-position instruction signal, the forward movement instruction signal, and/or the forward movement pause instruction signal may be automated signals delivered to the work vehicle for executing the commands or images rendered on a human readable display unit for instructing an operator actions to take for coupling the loader with the work vehicle.

A system for determining a position of a pin inserted within a pinhole of a work machine is disclosed. The system includes a follower, a sensor, and a controller. The follower is biased to be in contact with the pin to follow the pin throughout a movement of the pin within the pinhole. The sensor is configured to detect a state of the follower corresponding to the position of the pin with respect to the pinhole. The controller is configured to determine the position of the pin based on the state of the follower.

Proposed is a connection device for a detachable backhoe that allows a backhoe to be easily attached to or detached from a tractor and maintains the stable coupling state of the backhoe to the tractor so that the backhoe does not shake during operation thereof on the tractor. The connection device includes a fixing bracket mounted to the tractor, a rotating plate mounted to the backhoe and having a rotation recess formed on a lower portion thereof inserted into the insertion space, with first, second, and third hinge parts being formed on an upper portion of the rotating plate, first and second locking members installed on a first hinge part and a second hinge part, respectively, and a third locking member that is installed on the third hinge part to rotate in place together with a handle member and fixes the first and second locking members.
