US 8,897,972 B2 · Harvester load control system

Abstract

A method of controlling a multiengine harvester including the steps of operating the harvester in a first mode, operating the harvester in a second mode, and selecting less than all of the power absorbing loads to be driven. In the first mode, the harvester is operated using a first engine and a second engine to drive the plurality of power absorbing loads. In the second mode, the harvester is operated with the second engine being uncoupled from all of the power absorbing loads. In the selecting step, less than all of the power absorbing loads are selected to be driven dependent upon the sensed load on the first engine while operating in the second mode. The first engine is incapable of driving all of the power absorbing loads.

Dependent claims

A multi-engine agricultural harvester, comprising:

a plurality of power absorbing loads;
a first engine configured to supply power to a portion of said plurality of power absorbing loads, said first engine not being capable of powering all of said plurality of power absorbing loads;
a second engine;
and
a controller configured to function in a plurality of modes including a first mode and a second mode, said controller functioning in said first mode using said first engine and said second engine to drive said plurality of power absorbing loads, said controller functioning in said second mode when said second engine is uncoupled from all of said power absorbing loads, said controller being further configured to select less than all of said power absorbing loads to be driven by said first engine while operating in said second mode dependent upon a sensed load on said first engine.
