Harvester louver rotation

A method comprising:

• moving an output member of an actuator;
• transmitting motion of the output member to a first set of louvers supported in a first cleaning zone of a harvester along a first inclined plane to rotate the first set of louvers;
• and
• transmitting the motion of the output member to a second set of louvers supported in a second cleaning zone of the harvester along a second inclined plane, different than the first inclined plane, to rotate the second set of louvers, wherein rotation of the first set of louvers in response to actuation of the actuator is proportional to rotation of the second set of louvers in response to the same actuation of the actuator, wherein the first set of louvers rotate by a first angular extent in response to an actuation of the actuator and wherein the second set of louvers rotate by a second angular extent, different than the first angular extent, in response to the actuation of the actuator.

A harvester comprising:

• a head to separate crop from a growing medium;
• a threshing mechanism to thresh the crop;
• a cleaning shoe to clean the threshed crop, the cleaning shoe comprising:
• a first cleaning zone extending in a first inclined plane, the first cleaning zone comprising a first set of louvers;
• a second cleaning zone extending in a second inclined plane different than the first inclined plane, the second cleaning zone comprising a second set of louvers;
• a reciprocating drive to reciprocate the first cleaning zone with the first set of louvers and the second cleaning zone with the second set of louvers;
• a first set of louver wires coupled to the first set of louvers;
• a second set of louver wires coupled to the second set of louvers;
• at least one adjustment arm having slots receiving the first set of louver wires and the second set of louvers;
• and
• a linear actuator operably coupled to the at least one adjustment arm, wherein the linear actuator concurrently moves the at least one adjustment arm to concurrently rotate the first set of louver wires and the second set of louver wires to concurrently rotate the first set of louvers and the second set of louvers, wherein the at least one adjustment arm comprises a single adjustment arm comprising a first portion extending parallel to the first inclined plane, a second portion extending parallel to the second inclined plane and an intermediate portion connecting the first portion to the second portion.
