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.

Abstract: A grain tank on a crop harvester includes a belted conveyor floor for moving grain in the grain tank toward an opening through which the grain tank is emptied. A sensor determines when the grain has depleted the tank to a substantially low level and activates the floor to remove the remainder of the grain material.

The active floor may be provided in an belt in which the driven side has a lower friction material so as to improve belt life.
