Abstract

A harvester including: a chassis; an adjustable feeder housing carried by the chassis and defining a face angle relative to a ground plane; a header carried by the chassis, the header including: a header frame; at least one harvesting element carried by the header frame; and at least one divider pivotably carried by the header frame and defining a divider angle relative to the ground plane; and a mechanical linkage coupling the feeder housing to the at least one divider such that the divider angle is adjustable independently of movement of the header frame.

First claim

The invention claimed is:

1. A harvester, comprising:
a chassis; and
a header carried by the chassis, the header including:
a header frame;
at least one harvesting element carried by the header frame;
a plurality of dividers pivotably carried by the header frame, each of the plurality of dividers defining a respective divider angle relative to a ground plane;
a plurality of actuators carried by the header frame, each of the plurality of actuators coupling to a respective one of the plurality of dividers and being configured to control the respective divider angle of the respectively coupled divider;
a controller operatively coupled to the plurality of actuators and configured to activate each of the plurality of actuators independently of the other actuators; and
an adjustable feeder housing carried by the chassis and defining a face angle relative to the ground plane and an angle sensor associated with the feeder housing and operatively coupled to the controller, the controller being configured to detect a change in the face angle and activate at least one of the plurality of actuators responsively to detecting the change in the face angle.

2. The harvester of claim 1 , wherein the controller is configured to activate each of the plurality of actuators responsively to detecting the change in the face angle.

3. The harvester of claim 1 , further comprising a divider support connected to one of the plurality of actuators and bearing on a respective one of the plurality of dividers.
