Abstract: 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.

Abstract: A lift arm structure for a power machine with a frame can include a multi-bar linkage that is pivotally secured to the frame and a leveling link that is pivotally secured to the multi-bar linkage. The leveling link can be configured to transmit force from the leveling link to an implement as the multi-bar linkage is actuated to raise or lower the implement, including via a multi joint member that is pivotally secured to the leveling link, the multi-bar linkage, and an actuator that is configured to move the implement.

Abstract: Implementations of the present disclosure are generally directed to activating features in power machines. More particularly, implementations of the present disclosure are directed to remote activation of features in power machines. Implementations include, methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for transmitting a request for an initialization indicator for a software package from an initialization system of a power machine comprising hardware physically capable of executing at least one function, the request being transmitted, by a communication link of the initialization system, from a machine controller of the initialization system to a remote system, communicating, by the communication link, the initialization indicator from the remote system to the machine controller, and in response to receiving the initialization indicator: storing, by the machine controller, the initialization indicator, and executing, by the machine controller, the software package to control the at least one function.

Abstract: Disclosed embodiments include hydraulic systems which provide power to lift, tilt and auxiliary (e.g., implement) functions, including high-flow auxiliary functions, with increased efficiency. Disclosed embodiments incorporate a single variable displacement pump that supplies pressurized fluid to a main control valve (e.g., for lift, tilt, and auxiliary functions) and a bypass circuit. The main control valve supplies fluid to control lift, tilt, and auxiliary flow for implements. The bypass circuit combines flow with the output of the auxiliary section of the main control valve to optionally provide high-flow for selected implements. The single variable displacement pump can then be set to different output flow levels, with the bypass circuit functioning differently under different conditions to optimize hydraulic flow to carryout various tasks under various conditions.

Abstract: Disclosed embodiments include power machines, implement coupling systems and methods in which hydraulic or electric coupling between an implement and the power machine is made automatically using an existing actuator, for example a tilt actuator, of the power machine. Thus, additional actuators are not required to achieve hydraulic or electric coupling. In exemplary embodiments, power coupling is also free from the process of mechanically coupling the implement to the implement carrier. Also, in exemplary embodiments, a machine side coupler assembly moves with the implement after a connection is established, despite the implement coupler assembly being removed from the implement carrier. This allows the same implement carrier to be used on all similarly sized machines.

Abstract: A clamp implement and a control system for controlling the clamp implement such that the clamp implement can be caused to follow motion of a bucket or other primary implement in a selected mode of operation. In another mode of operation, the claim implement can be caused to move independently of the primary implement.

Abstract: Disclosed are power machines, and drive systems for use thereon, as well as methods of providing automatic gear shifting. The drive system includes a controller configured to implement automatic gear shifting. Gear engagement is determined following a gear shift, and a drive pump or other drive system components is automatically controlled to rotate a gearbox gear in first and second directions until the gear is properly engaged.
