Abstract: A method of controlling a lift arm actuator (514) and a tilt actuator (524) to control positioning of an implement carrier (530) coupled to a lift arm (520) of a power machine. An activation signal is received from an enabling input device (570). A lift arm control signal is received from a lift arm control input (562) commanding movement of the lift arm. The lift arm actuator is controlled responsive to receipt of both of the activation signal and the lift arm control signal to move the lift arm to a target lift arm position and to move the implement carrier to or maintain the implement carrier at a target implement carrier orientation relative to a gravitational direction.

Abstract: Disclosed end-user devices (100) include a processing unit (102) and transceiver circuitry (142, 144) configured to communicate wirelessly with corresponding transceiver circuitry (242; 244) of a network device (220). Memory (104) of the end-user device stores network device configuration data and instructions to configure the network device, and stores a network device configuration application (200) executable by the processing unit to facilitate configuring the network device by wirelessly transmitting the network device configuration data and instructions to the network device using the transceiver circuitry'. The network device configuration application also configures the end-user device to monitor and diagnose the network device through a communications channel established by the transceiver circuitry (142, 144) of the end-user device and the transceiver circuitry (242; 244) of the network device.

Abstract: Tracked vehicles (100, 200, 300) and drive systems for tracked vehicles including a guard or shield (380) for a drive motor (350) that deflects debris drawn into a space where the drive motor is located. The guard also provides a longer critical path (370) between the outside of a drive motor assembly and an inside of the drive motor assembly.

Abstract: Power machines (100; 200; 400) such as excavators with control inputs (466; 468) that are configurable to control various functions on the excavator. In some modes, selected control inputs are manipulable to control the position of a lift arm (230), bucket, and house (211) position. In other modes, the same control inputs are used to control travel and an implement (334) on an undercarriage (212).

Abstract: Disclosed are excavators or other power machines having a lift arm structure (e.g., 230; 434; 534) with a bucket (e.g., 405; 505) coupled to an arm (e.g., 434; 534) to pick up material during a digging or scooping operation, and a bucket cleanout device (e.g., 420; 520) to aid in removal of material from the bucket. The bucket cleanout device includes components (e.g., 410; 510) which are rotatably coupled to a support structure, such as the arm, an implement carrier and/or the bucket and configured to aid in removal of material during a material dumping movement of the bucket.

Abstract: Disclosed power machines (100; 200; 300; 400; 500) include a lift arm structure (230; 330; 430) having a first arm (234; 334; 434) pivotally mounted to a frame and a second arm (236; 336; 436), coupled to an implement interface (270; 370; 470), configured to telescopically extend from and retract into the first arm. A control system (160; 260; 360; 460) controls a first actuator (238; 335; 435) to raise and lower the first arm, and controls a second actuator (239;) to extend and retract the second arm relative to the first arm. The control system is configured to control the first and second actuators to implement a lift operation, responsive to an operator input. During the lift operation, the first actuator raises the first arm and the second actuator extends and retracts the second arm to maintain a substantially linear path (339; 439), such as a vertical path, of the implement interface or an implement attached to the implement interface.

Abstract: Power machines (100; 200; 400; 700) such as excavators having a house (211; 711) that rotates about a vertical axis on an undercarriage are disclosed. In certain conditions, a control system (160; 260; 460) on the excavator can limit rotational movement of the house and/or pivoting of a swing function on a lift arm (130; 230; 730) to contain work performed by an implement to a predefined range or work area.

Abstract: Power machines (300) and control systems (360, 400) used thereon include a lift cylinder (333), a tilt cylinder (335), and a slave cylinder (337) mechanically connected to assist the lift cylinder with raising a boom (330). With a lift control valve (405) controlled to cause extension of the lift cylinder to raise the boom, pressure from a hydraulic source (362) is provided to the slave cylinder to aid in raising the boom. Resulting increased pressure on a side of the slave cylinder opens load holding valves (370, 460), allowing hydraulic pressure from the tilt cylinder to be communicated to the slave cylinder such that tilt cylinder pressure due to a heavy load on an implement aids in raising the boom.
