The mobile spraying machine is supplied with the product to be sprayed under pressure from a stationary tank via a flexible hose and an atomiser, which can be shut off as desired. A battery of spray nozzles are mounted on one or more vertical standpipes, connected by the hose to the supply. Each standpipe is secured by a holding arm adjustable along a stem. A handle for manipulation by a standing person is secured to the chassis by a bar, and the supply to each standpipe is regulated by a pedal-operated valve on the lower part of the machine. The chassis holds the complete machine in equilibrium.
