A wheel loader machine includes a bucket configured to hold a predetermined load of a granular or powder material, a hydraulic system having an electro-hydraulic actuator to move the bucket over tilt angles and to shake the bucket, a hydraulic sensor configured to detect hydraulic pressure, an interface configured to receive input parameters and to output status information of the bucket, and a controller. The input parameters including a target weight of the granular or powder material. The status information including weight of the granular or powder material in the bucket determined using the detected hydraulic pressure. The controller configured to control the hydraulic system to tilt the bucket to a predetermined tilt angle and to shake the bucket in accordance with an agitation pattern until the weight of the granular or powder in the bucket is at or below the target weight of the granular or powder material.

A power machine can include operator input devices and a control system configured to command movement of actuators based on operator inputs received from the operator input devices. Movement of one or more of the actuators can be commanded based on input at one or more of the operator input devices and a response curve selected from a plurality of different response curves. Movement of one or more of the actuators can be based on a selected control mode for the power machine that corresponds to a selected control-function mapping of the operator input devices to the one or more actuators. A lift arm can be variously controlled to execute automatic or other operations. An excavator can be operated in a sustained-speed travel mode. Actuation of a bucket or other implement can be implemented based on signals from a material sensor.

An apparatus for facilitating bucket movement of a material handling machine includes a joystick biased to a neutral position, movable away from the neutral position in a first direction along an axis to a first position, and movable away from the neutral position in a second direction along the axis, opposite the first direction, to a second position. The apparatus further includes an operator input movable from a disengaged position to an engaged position in which a bucket of the material handling machine is configured to automatically move in an oscillatory motion. When the operator input is in the engaged position, an intensity of the oscillation is dependent upon a position of the joystick along the axis, decreasing along the axis from the first position to the second position.

A work machine includes an unload lever swingably supported by an operation box, the unload lever being configured to be swung to select whether or not to supply an operation fluid to the hydraulic actuator. The unload lever includes a second guide pin to move in a first guide groove in accordance with the swinging of the unload lever, the second guide pin being positioned on a first end of the first guide groove when the unload lever is positioned to a pushed-down position and positioned on a second end of the first guide groove when the unload lever is positioned to a pulled-up position. The first guide groove includes a first latch portion to latch the second guide pin at the first end of the first guide groove, and a second latch portion to latch the second guide pin at the second end of the first guide groove.

A method for controlling the operation of a work vehicle includes initially controlling an operation of an implement actuator of the vehicle based on operator inputs received from an input device while a load sensing system of the vehicle is operable to adjust an output of an associated pump. The method also includes receiving an input providing an indication that an implement-based movement operation is to be performed and deactivating the load sensing system in response to the indication that the implement-based movement operation is to be performed. In addition, the method includes controlling the operation of the implement actuator based on further operator inputs received from the input device to perform the implement-based movement operation while the load sensing system is deactivated.

A construction machine capable of reducing a resistance that a bucket receives from the ground and improving smoothness of a construction surface includes a working device including a working device body and a bucket, first and second bucket actuators that rotationally move the bucket, and a control device. The control device controls the second bucket actuator to make the second bucket actuator periodically oscillate the bucket in a direction of a yaw motion during excavation work or ground leveling work.

A system for controlling the operation of a work vehicle implement during an implement shake operation may include an implement configured to pivotably coupled to a loader arm. A controller may be configured to monitor an angle of the implement relative to the arm during the implement shake operation. Furthermore, the controller may be configured to determine first and second differentials between monitored angles of the implement during first and second cycles of the implement shake operation, respectively, and a predetermined average implement angle. Additionally, the controller may be configured to determine an estimated differential between an anticipated angle of the implement during a third cycle of the implement shake operation and the predetermined angle based on the first and second differentials. Furthermore, the controller may be configured to adjust a duty cycle and/or an amplitude of the third cycle of the implement shake operation based on the estimated differential.
