Operator control station and method for a work machine having more than one function
First Claim
1. A work machine comprising:
- a work machine body;
at least two controllers; and
at least one of said two controllers being operably coupled to a first set of equipment attached to said work machine body when said at least two controllers are in a first mode pattern;
at least one of said two controllers being operably coupled to a second set of equipment attached to said work machine body when said at least two controllers are in a second mode pattern; and
said at least two controllers being simultaneously operably coupled to at least a portion of said first set of equipment and to at least a portion of said second set of equipment when said at least two controllers are in a hybrid mode pattern.

Abstract
When operating a work machine having more than one function, there are situations in which an operator may need to simultaneously control both functions. For instance, when a backhoe loader operator would like to perform a maneuver referred to as the “duck walk”, the operator must simultaneously control at least one aspect of a backhoe and one aspect of a loader. A work machine that has an operator control station with at least two controllers, which may be assigned a first mode pattern, a second mode pattern, and a hybrid mode pattern. When the at least two controllers are in the first mode pattern, the at least two controllers are operably coupled to a first set of equipment, such as a loader. When the at least two controllers are in the second mode pattern, the at least two controllers are operably coupled to a second set of equipment, such as a backhoe. When the at least two controllers are in the hybrid mode pattern, the at least two controllers are simultaneously operably coupled to at least a portion of the first set of equipment (loader) and at least a portion of a second set of equipment (backhoe).
