Disclosed is a pavement washer having two sets of spray nozzles mounted on the front of a small tractor. Nozzles of the first set are aimed ahead substantially horizontally to throw a pattern of cleaning solution well ahead of the tractor, while the second set of nozzles are aimed sharply downward as well as forward to spray a pattern of water ahead of the tractor but behind the cleaning solution. Also disclosed is an arrangement for connecting the tractor to a stationary source of water through a hose wherein provision is made to shut off the ignition of the tractor before the hose is pulled taut.
