Abstract: Systems and methods for a power machine can provide greater functionality and operator comfort. A climate control system for a power machine can include a condenser, mounted on a front frame member of the power machine. Paths for air flow to cool an engine compartment can extend along airflow passages though a fuel tank. Secondary braking systems can allow a power machine to be stopped with modulated fashion when a primary power source is unavailable. Rear-view vision systems can include a camera mounted on a front pivoting frame (e.g., near the top of an operator station) to provide improved environmental information to an operator. A tilt actuator of the power machine can be configured to operate in a float mode.

Abstract: A hydraulic assembly for an extendable lift arm assembly can include an extension cylinder, a leveling cylinder, a main control valve, a flow combiner/divider, and one or more flow-blocking arrangements. The main control valve can be configured to control commanded movement of the extension and leveling cylinders of the lift arm assembly. The flow combiner/divider can be configured to hydraulically link the extension cylinder with the leveling cylinder for synchronized operation of the extension cylinder and the leveling cylinder. The one or more flow-blocking arrangements can be configured to restrict flow from rod or base ends of the leveling or extension cylinders during commanded extension or retraction of the leveling and extension cylinders, or in the absence of commanded movement of the leveling and extension cylinders, to maintain synchronized orientation of the leveling and extension cylinders.
