摘要： Disclosed embodiments include power machines with a lower implement pivotally coupled to an undercarriage frame by a lower lift arm structure and which include one or more cylinders or actuators that are operable to pivot the lower lift arm structure and lower implement relative to the undercarriage frame. A configuration of the one or more cylinders which mounts the cylinders behind the lower implement, with attachments to the undercarriage and to the lower lift arm structure at positions which allow the cylinders to be surrounded and protected by the undercarriage, reduces damage to the cylinders during operation.

摘要： A power machine having a frame and a cab pivotally attached to the frame at a first cab pivot, such that the cab pivots about a first transverse axis from an operational position to a service position, includes a link mechanism and a first spring. The link mechanism includes a first link having a first link end, a second link end, and a first pivot engagement feature pivotally coupling the first link to the frame and to the cab such that the first link is pivotal about the first transverse axis. The second link end is configured to interface with the cab at a position forward of and below the first cab pivot and first pivot engagement feature when the cab is in the operational position.

摘要： Power machines and loaders having doors with an integrated display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., that allows the operator of the machine to see the displayed information closer to the line of sight with the work area. The display can show augmented reality information about a worksite.

摘要： A control device for a power machine can be configured to receive a request to initiate a power burst mode for the power machine, wherein the power burst mode defines one or more operational parameters for increasing an amount of power used by at least one of the plurality of electrical actuator. The control device may receive data associated with one or more operational conditions of the power machine and assess a power burst constraint associated with the power burst mode. In response to the power burst constraint being satisfied, the control device may control power to at least one of the plurality of electrical actuators according to the one or more operational parameters of the power burst mode.

摘要： Methods and systems are provided for controlling automatic travel of a power machine, particularly a mower. A set of points associated with a geographical area can be used to define a work path for a work task associated with the geographical area. The power machine can be controlled to perform the work task by traveling along the work path.

摘要： A control device for a power machine can be configured to determine an operating temperature of a power machine and to derate one or more electrical actuators of the power machine to limit regenerative charging to the electrical power source. A method of operating a power machine can include controlling one or more electrical actuators, with a control device, to cause an implement of a power machine to fluctuate in orientation over a plurality of cycles, based on receiving an operator input that initiates the fluctuation or detecting an operational condition of the power machine.

摘要： Disclosed are power systems, and power machines employing the power systems, having dual in-line pumps configured to supply hydraulic fluid to respective left and right side travel motors of the power machine. In some exemplary embodiments, pump pintle arm controls and a single centering mechanism for the pintle arm controls are provided. The single centering mechanism is configured to center the pintle arms for each of the two pumps. Also in some exemplary embodiments, a mechanical control linkage configuration allows the separate pump pintle arm controls to be positioned on a side of the pump substantially one behind the other. This allows hydraulic connections to the pumps to be placed on top of the pump assembly, improving the routing of hydraulic hoses in the power machine.

摘要： A lift arm structure for a power machine with a frame can include a lift arm and an electrical lift actuator. The lift arm can be configured to be movably secured to the frame to extend along a lateral side of the frame. The electrical lift actuator can be secured to the lift arm within a pocket defined by the lift arm and can be configured to extend and retract between the lift arm and the frame of the power machine to raise and lower the lift arm.
