Embodiment Construction

[0024] The concepts disclosed in this discussion are described and illustrated with reference to exemplary embodiments. However, these concepts are not limited in their application to the details of construction and arrangement of components in the illustrated embodiments, and can be practiced or carried out in various other ways. The terminology herein is used for the purpose of description and should not be regarded as limiting. Words such as "comprises," "comprising," and "having" and variations thereof as used herein are intended to encompass the items listed thereafter, equivalents thereof, and additional items.

[0025] The disclosed embodiments illustrate an excavator and a control system for the excavator, wherein the excavator and the control system provide multiple modes of operation. The control system includes operator input devices for controlling movement of various portions of the lift arm, movement of the tool relative to the lift arm, oscillation of the lift ...

Abstract

Power machines (100; 200; 400; 700) such as excavators having a house (211; 711) that rotates about a vertical axis on an undercarriage are disclosed. In certain conditions, a control system (160; 260; 460) on the excavator can limit rotational movement of the house and / or pivoting of a swing function on a lift arm (130; 230; 730) to contain work performed by an implement to a predefined range orwork area.

Description

technical field [0001] The present disclosure relates to power machines. More specifically, the present disclosure relates to a power machine having a lifting arm that is movable laterally relative to at least a portion of the power machine, and control of the lateral position of such a lifting arm. One type of power machine that has a lift arm movable laterally relative to at least a portion of the power machine is an excavator. Another example of such a power machine is a tractor-loader-backhoe. In some cases, a power machine such as a skid steer loader may have a backhoe-style implement mounted to the loader that is also movable laterally relative to the loader. Background technique [0002] For the purposes of this disclosure, a powered machine includes any type of machine that generates power for the purpose of accomplishing a particular task or tasks. One type of powered machine is a work vehicle. Work vehicles are typically self-propelled vehicles that have work e...
