Abstract
When operating a work machine such as a backhoe, fuel consumption, pollution and noise can be decreased by reducing engine speed below a throttle setting when a set of equipment attached to a rear side of a work machine body is idled for a predetermined period of time. The engine speed is reduced by a control system including an electronic control module having an engine speed reduction algorithm. When the electronic control module determines that a seat assembly that is rotatably mounted to the work machine body is in a forward-facing position, the engine speed reduction algorithm is inactive. When the electronic control module determines that the seat assembly in a rearward-facing position, the engine speed reduction algorithm is active. By basing, at least in part, the activation and deactivation of the engine speed reduction algorithm on the seat assembly position, the engine speed reduction algorithm will be active when the backhoe is operable.
