Abstract
A sprayer has a tank for holding a spray solution that is applied to a ground or turf surface. The sprayer includes an agitation system having a plurality of agitation nozzles that extend into the tank that are accessible from outside the tank and can be removed and replaced without using tools. The sprayer may include a rinse system carried onboard the sprayer which is segregated from the spray and agitation systems to avoid contaminating the rinse liquid prior to the time the rinse liquid is sprayed into the tank through rinse nozzles. The rinse nozzles include upwardly and downwardly directed nozzle ports and a bottom spinner for thoroughly cleaning all interior surfaces of the tank. The sprayer may also include a chemical eductor mounted on the side of the tank, whose weight is counterbalanced by springs, and which easily pivots between lower and upper positions on the tank.
