Abstract: A power machine can include a frame, a lift arm, and one or more electrical devices for control of one or more work elements. The electrical devices can be controlled to improve positional accuracy for work elements during work operations, to improve power management and customer experience (e.g., to provide smoother ride during drive operations), and to provide float functionality for work elements.

Abstract: A control system is provided for a first power machine having a first actuator and a second power machine having a second actuator. The first power machine includes a first user input device. Aa first user input corresponding to a power machine operation can be received via the first user input device and a control mode for controlling the execution of the power machine operation can be determined. Controlling the execution of the power machine operation can selectively include: in a local control mode, controlling the first actuator to execute the power machine operation with the first power machine; and in a remote control mode, controlling the second actuator to execute the power machine operation with the second power machine.

Abstract: A tractive element for a power machine can include a frame, an endless track, a drive sprocket, and a first set of split rollers. The first set of rollers can include a first roller rotatably coupled to the first plate with a first axis of rotation and a second roller rotatably coupled to the second plate with a second axis of rotation. The first axis of rotation and the second axis of rotation can be spaced apart from one another with a first roller offset distance, along a front-to-back direction of the tractive element, that can provide improved ride quality.

Abstract: A mower deck includes a top deck, a front wall, a rear wall opposite the front wall and a first side wall. The first side wall extends between the front and rear walls. A front baffle assembly extends downwardly from the top deck. The front baffle assembly extends from the first side wall toward a discharge opening that is positioned between the front and rear walls at a discharge side of the top deck. The front baffle assembly is configured to urge cut grass and debris toward the discharge opening. A discharge baffle is positioned proximate a rear end of the discharge opening and extends downwardly from the top deck. The discharge baffle and the rear wall define a discharge gap. The discharge gap is positioned on an opposite side of the discharge baffle from the discharge opening. The discharge gap is configured to allow airflow into the mower deck.

Abstract: A power machine can be configured to automatically travel along a planned path based on pursuit of a target point. A location of the target point along the planned path can be determined based one or more of local curvature of the planned path or travel speed of the power machine. In some cases, a circular buffer can be used to store mapping data.

Abstract: Disclosed embodiments include implements with a linkage and suspension configured to provide downward pressure on tool to allow it to maintain a desired level of contact with a work surface. An adjustable biasing member such as an air bag provides upward pressure on the linkage to reduce downward pressure on the work surface from the tool. Shock absorbers can also be included to hold the linkage in place and limit bouncing of the tool when it is being transported.

Abstract: A power machine can include a traction lock system to stop movement of the power machine. The traction lock system can include a controller configured to receive a brake input from an operator. In response to receiving the brake input, the controller can temporarily command a target (e.g., reduced) speed of the engine before engaging the brake.
