摘要： The present invention is directed to a computer based control system for controlling hydraulic and electromechanical actuators on a power machine, such as a skid steer loader. The computer based control system is configured to implement a number of features to enhance certain operational aspects of the power machine. One such feature includes an operator actuable selector which provides a selector signal based on an operator input. A controller receives the selector signal and provides an auxiliary output signal to control an auxiliary valve in a selected one of an on/off mode and a proportional mode based on the selector signal.

摘要： A work vehicle includes an attachment. The work vehicle also includes a lift assembly coupled to the attachment, wherein the lift assembly is configured to lower and to raise the attachment. The lift assembly includes a pair of lift arms. The lift assembly also includes an X-shaped cross tube coupled to and extending between the pair of lift arms. The X-shaped cross tube includes apertures configured to provide visibility between the pair of lift arms of a bottom edge of the attachment to an operator within the work vehicle when the attachment is at a full lift height.

摘要： A loader can include a lift arm structure coupled to a frame. The lift arm structure can move between a fully-lowered position and a fully-raised position and can include a lift arm and a connecting link. A first end of the connecting link can be pivotally coupled to the frame at a first pivot point and the lift arm can be pivotally coupled to a second end of the connecting link a second pivot point. The lift arm structure can further include a lift actuator configured to pivot the lift arm about the second pivot point and an extension actuator configured to pivot the connecting link about the first pivot point. The extension and lift actuators can be controlled to move the lift arm along a variety of travel paths between any two points within a lift envelope of the lift arm structure.
