A ground sprayer includes a front portion and a rear portion. A marking fluid is stored in a fluid reservoir removably mounted in the front portion. A pump disposed in the front portion draws the marking fluid from the fluid reservoir through a manifold, and the pump drives the marking fluid out of a nozzle. An actuator is disposed in the rear portion and can activate the pump based on a command from the user. The rear portion includes a handle such that the user can fully support and operate the ground sprayer with a single hand.
