Abstract: Disclosed embodiments include travel motor hydraulic circuits for controlling the provision of hydraulic fluid to a travel motor. The travel motor hydraulic circuits include a counterbalance valve configured to block the flow of hydraulic fluid when in a neutral position to prevent unintended movement of a power machine, and an anti-cavitation valve configured to direct flow of hydraulic fluid back to the travel motor to prevent cavitation.

Abstract: A cab for a power machine having a side window and a rear window each hingedly connected to the same one of a right rear cab frame post and a left rear cab frame post such that when the side window and rear window are both opened by latches to rotate outward relative to the same rear post an airflow path is created diagonally across the operator between a front corner of the cab and an opposite rear corner of the cab.

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.

Abstract: Power machines with implement carriers that can sense the proximity of an implement to the implement carrier with a plurality of sensors. Such sensing is indicative of the likelihood of an implement being positioned adjacent to the implement carrier. In some embodiments, a sensor detects whether a locking mechanism is activated.

Abstract: A man-lift implement configured to be mounted on an implement carrier that is rotatably attached to an arm of an excavator includes an implement carrier interface configured to mount the man-lift implement to the implement carrier of the excavator, a basket configured to carry an operator, and a multi-bar linkage and a rotational actuator coupled between the implement carrier interface and the basket. The multi-bar linkage has a linkage actuator and is moveable under power of the linkage actuator to raise and lower the basket relative to the implement carrier interface, and the rotational actuator is configured to pivot the basket with respect to the implement carrier interface.

Abstract: The present disclosure includes independent suspension systems or members, as well as wheeled skid steer loaders or other power machines including the same, that couple each wheel to a machine frame using a four-bar linkage, with the four bars including the frame of the machine, an upper control arm, a lower control arm, and a wheel carrier link. Each control arm is pivotally attached to both the machine frame and one end of the wheel carrier link. The four pivots between the control arms and the wheel carrier link are configured to all be contained within cylinder defined by the outer diameter of the wheel rim, allowing for a compact structure with the wheel carrier link and at least part of the control arms being positioned within this volume when the loader is in a resting position.

Abstract: Disclosed are embodiments of a track mounting tool for use with track removal from, and mounting on, a power machine. The tool includes features which aid in the tasks of track removal and/or track installation. In exemplary embodiments, the tool includes track hanger towers which are configurable to carry a track for mounting on, or after removal from, either side of a power machine. The tool includes a track engager mechanism, which is pivotable for use with either side of a power machine or for mounting of a track at a front or rear idler.
