A windguard is provided that may be used with an agricultural harvester, such as around baler, waste baler, combine, sugarcane harvester or cotton harvester. More particularly, the windguard utilizes at least a first and a second pivot tab, each comprising a cam that is adapted for alignment into a slot along a first and second side arms of the windguard and that allows a upward or downward movement of the pivot tabs in the slot. The sliding motion of the cam in the slot allows the windguard to automatically adjust during operation without manual adjustment or pre-adjustment prior to operation.
