An actuated shear pin includes an actuator and pin body coupled to the actuator. The actuator selectively configures the pin body in a locking configuration or a stowed configuration. In the locking configuration, the pin body is placed in a travel path of two components configured to move relative to each other, to inhibit such relative movement. In the stowed configuration, the pin body is out of the travel path, thereby allowing the two components to move relative to each other.

Control system for actuated pins

A hydraulic system for controlling an implement on a work machine may include a hydraulic reservoir, a hydraulic pump in fluid communication with the reservoir, a central valve in fluid communication with the pump and configured for controlling the implement, a load sense pressure relief system, and a controller. The controller may be configured for controlling the central valve and the load sense pressure relief system and selecting between operating the hydraulic system at a first pressure and a second pressure based on a factor relating to implement position.

Variable system pressure based on implement position

A bucket for an underground loading machine includes an opened bucket front and a concaved bucket back. To provide abrasive wear resistance, the bucket includes a paddle plate joined to the bucket underside of the bucket floor. The paddle plate can have a trumpet-shape tapering from flared forward edge to a plate tail disposed toward the concaved bucket back. The bucket may be configured as a wedge bottomed bucket and include a plurality of spacer wedges disposed between and spacing apart the bucket underside and the paddle plate.

A hydraulic system for controlling an implement on a work machine may include a hydraulic reservoir, a hydraulic pump in fluid communication with the reservoir, a central valve in fluid communication with the pump and configured for controlling the implement, a pressure relief system arranged in fluid communication with the hydraulic pump and the central valve, and a controller. The controller may be configured for controlling the hydraulic pump, the central valve and the pressure relief system and selecting between operating the hydraulic system at a first pressure and a second pressure based on a factor relating to implement position.

A service pin assembly for a machine includes a service pin and a tray for retaining the service pin. The tray is attachable to a frame of the machine, and is pivotable relative to the frame between a first position and a second position. In the first position, the tray facilitates a storage of the service pin with the machine. In the second position, the tray facilitates an engagement of the service pin with a lift arm of the machine and the frame to restrict a relative movement between the frame and the lift arm.

A lift arm for a loader can comprise a pivot end section extending along a first axis and including a first pin hole defining an origin at the intersection of x- and y-axes, a bucket end section extending along a second axis and including a second pin hole located a first distance away from the origin on the y-axis, and a hump section connecting the pivot and bucket end sections comprising a lifting cylinder coupler section including a third pin hole located a second distance away from the y-axis and a torque tube coupling section.
