Abstract: A sprayer boom for a mobile landscape spraying apparatus having a wheeled chassis for movement of the spraying apparatus relative to a ground surface includes a sprayer boom assembly. The sprayer boom assembly includes an outer boom section that supports a spray nozzle for spraying a material onto the ground surface. A motor is configured to move the outer boom section relative to the chassis between an extended, sprayer mode position and a retracted, storage position. The outer boom section is capable of breakaway motion in the sprayer mode position in response to encountering an obstruction.
