Armrest control center with spray boom control
An armrest control center can be configured on with respect to an armrest of a chair in an operator cab of an agricultural machine to have physical inputs which can be quickly and easily controlled by an operator in the cab to affect automatically controlled sprayer boom functions so that the operator is not distracted by cumbersome menus on a computer screen. Such physical inputs can include push buttons and/or a joystick. Such sprayer boom functions can include activating or deactivating automatic sprayer boom height control, adjusting automatic sprayer boom height settings, and folding and/or unfolding the sprayer boom.
