One exemplary embodiment includes a holster structure and a spray tank, with the holster structure attaching to the push rails of a push mower and the spray tank mounting removably to the holster structure. This arrangement provides easy and convenient access to the sprayer function as a user mows his or her lawn, eliminating the need to make kill weeds and mow as separate tasks. Moreover, some embodiments provide a dual chamber tank, which provides further efficiency by allowing users to choose between weed killers, or other lawn or garden treatments while mowing. ## Claims ### Claim 1 An assembly comprising: a first spray tank in fluid communication with a spray nozzle, with the spray tank having a sidewall; a holster structure removably attached to the sidewall of the spray tank and configured to removably attach to first and second push rails of a lawnmower, wherein the holster structure includes at least one storage compartment for lawn tools or other items, and wherein the first spray tank is configured for removal and use separate from the holster structure while the holster structure is attached to the rails of the lawn mower. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the holster structure includes first and second opposing sides, with the first side having at least one clamp configured to clamp onto the first push rail and the second side having at least one clamp configured to clamp onto the second push rail. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the holster structure includes a top and a bottom, with the top contacting the sidewall of the first spray tank and wherein the at least one storage compartment is closable. ### Claim 4 (depends on 3) The assembly of claim 3, wherein the bottom of the holster structure includes another storage compartment. ### Claim 5 (depends on 1) The assembly of claim 1, further comprising at least one back strap connected to the first spray tank. ### Claim 6 (depends on 1) The assembly of claim 1, further comprising a second spray tank attached to the holster structure, with second spray tank sharing a common sidewall with the first spray tank and being in fluid communication with the spray nozzle. ### Claim 7 An assembly comprising: a push lawn mower having first and second push rails; a holster structure attached to the first and second push rails and having a top and a bottom, with top having first and second storage regions and a central region therebetween; a dual spray tank assembly removably attached to the central region of the holster structure and having at least one back strap for carrying the dual spray tank assembly, the dual spray tank assembly having first and second spray tanks sharing a common sidewall and in fluid communication with a common spray nozzle. ### Claim 8 (depends on 7) The assembly of claim 7, wherein the base structure includes a plastic plate structure and a pair of metal brace members which extend through the plate structure between the first and second push rails. ### Claim 9 (depends on 7) The assembly of claim 7, wherein the first and second storage regions are integrally molded into the plastic plate structure. ### Claim 10 A method comprising: attaching a holster structure between first and second push rails of a lawn mower; installing a spray tank in or on the holster structure, with the spray tank having a spray nozzle in fluid communication therewith; operating the lawn mower to mow at least a portion of a lawn; and operating the spray nozzle to spray a portion of the lawn while the lawn mower is operating; wherein operating the spray nozzle includes operating the spray nozzle to spray a first lawn-safe herbicide from the first spray tank to a first portion of the lawn, and operating the spray nozzle to spray a non-lawn-safe herbicide from the second tank to a second portion of the lawn. ### Claim 11 (depends on 10) The method of claim 10, wherein installing the spray tank in or on the holster structure includes installing a dual spray tank in or on the holster structure, wherein the dual spray tank includes first and second spray tanks sharing a common sidewall.
