Abstract: A control system of a power machine can be configured to allow certain power machine functionality based on a wireless connection with a mobile device. For example, a power machine can operate in a startup mode providing limited functionality to an operator (e.g., engine power, but no workgroup actuators). Access to additional power machine functionality (e.g., full functionality) can then be permitted based on establishing a wireless connection to a mobile device that corresponds to an operator profile for the power machine.

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: A power machine configured as a mini-loader includes a mini-loader frame defining a front end opposite a rear end and a first side opposite a second side, at least one first-side motor supported by the first side of the frame, at least one second-side motor supported by the second side of the frame, and four endless track pods. The four endless track pods include a first endless track pod and a second endless track pod supported by the first side of the frame, and a third endless track pod and a fourth endless track pod supported by the second side of the frame. The endless tracks of the first and second endless track pods are powered by the at least one first-side motor and the endless tracks of the third and fourth endless track pods are powered by the at least one second-side motor to propel the power machine.

Abstract: 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.

Abstract: A control system for a hydrostatic drive system can include a hydraulic charge pump circuit having a hydraulic load and a tank. The hydraulic charge pump can be in fluid communication with the hydraulic charge pump circuit. A bypass line can extend to the tank from a junction between the hydraulic charge pump and the hydraulic load. A charge bypass valve can be disposed to control flow through the bypass line. The control system can include a control device configured to determine one or more operational parameters for the power machine and control the charge bypass valve to allow flow through the bypass line, from the hydraulic charge pump to the tank, based on the determined operational parameters during a starting 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: Disclosed embodiments include post driving implements which attach to a power machine such as a loader in order to pick up posts of various sizes and materials and/or to drive the posts into the ground. In some exemplary disclosed embodiments, the post driving implement allows a post to be picked up when positioned inline with a direction of power machine travel and allows the post to rotate under the force of gravity to a second position in which the post is inline with a pounding mechanism for pounding the post into the ground. Catch mechanisms can be included to capture a portion of the implement to maintain the post in the second position until a release action is taken or a release command is given.
