An attachment for a host vehicle includes an attachment plate configured to attach to the host vehicle and a boom coupled to the attachment plate by way of a pivot hinge and a lift hinge. A pivot actuator is coupled to the attachment plate and to the boom and configured to horizontally transition the boom about the pivot hinge, and a lift actuator is coupled to the attachment plate and to the boom and configured to vertically transition the boom about the lift hinge.

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.

A work machine comprises a tilt rotator to control rotation of a tool, a coupler to couple and decouple the tool to/from the tilt rotator, a display to output information to an operator of the work machine, an operator interface to receive input from the operator, and processing circuitry. The processing circuitry is configured to output, on the display, a rotation instruction for the operator to initiate a rotation operation of the tilt rotator, in a case that the tilt rotator is determined to be in an incorrect position, stop the rotation operation of the tilt rotator under a condition that the tilt rotator is determined to be in a correct position based on a rotation angle of the tilt rotator about a rotational axis, the rotation operation being initiated by a rotation input via the operator interface.

A quick coupler and methods of coupling and decoupling a quick coupler and work tool are disclosed. The quick coupler includes a frame, cylinder, primary blocking member, secondary blocking member, biasing member, and controller. The method of coupling includes activating an AUTOMATIC LOCKING state, automatically locking a second tool pin within a hook, a first tool pin entering a notch, and activating a LOCKED state. The method of decoupling includes activating the AUTOMATIC LOCKING state, resting the work tool on a surface, activating an UNLOCKED state, and separating the quick coupler and work tool. Advantageously, the quick coupler can automatically lock the second tool pin without actuation of the cylinder.

A method of measuring a depth in an a excavator uses a pressurized hydrostatic electronic altimeter, and attaches a reference cell of an electronic elevation measuring device to an arm of the excavator. The dual bore tube associated with the elevation measuring device is run from the reference cell to a display in an area of a cab of the excavator. The reference cell is zeroed, while holding a portion of a digging portion of the excavator near the ground, then the trench is dug, and a depth of digging with the excavator is determined, by pressing the digging portion of the excavator against the bottom of the excavated portion, and measuring the depth using the device

A bracket for mounting an excavation bucket on a coupler of an articulated arm. The bracket comprises a body extending in a plane and having a central portion. A first concavity on a first side of the body substantially has an arc-of-circle shape to conform with a surface of a cylinder and hinge therearound. The bracket comprises a second concavity on a second side of the body opposite the first side with respect to the central portion. A third concavity on the second side of the body substantially has the arc-of-circle shape. The bracket comprises a first abutment edge formed by the central portion of the body; and a second abutment edge aside the first abutment edge and further from the central portion of the body compared to the first abutment edge. This bracket allows reversible mounting of the coupler of the excavation bucket.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, a covering attached on the upper turning body, and a camera for surroundings monitoring placed on the upper turning body. A cut is formed in the covering. The camera is placed on the upper turning body such that at least part of the camera is within the covering through the cut.

The present invention provides a coupling apparatus for coupling an attachment to a dipper arm of a machine. The apparatus includes a coupler body; a first, fixed engaging means mounted on the coupler body for engaging a first coupling pin of the attachment, in use; a latch member associated with and pivotable with respect to the first, fixed engaging means between latched and unlatched positions; and a locking member pivotable about a pivot point between first and second positions, and provided in mechanical communication with the latch member. The latch member includes an aperture located therethrough, and the locking member includes a trunnion member or other such protrusion located thereon, extending into or through the aperture of the latch member and engaging the same such that when the locking member is in the first position, the latch member is in the latched position, and when the locking member is moved to the second position, the trunnion member moves the latch to the unlatched position.

A coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.
