Chemical agent application system that is removably attachable to a lawn mowing tractor

A chemical agent application system that is removably attachable to a lawn mowing tractor, comprising:

• a chemical agent tank having a bottom panel, a first sidewall, a second sidewall, a slanted front panel, a slanted rear panel, and a top panel interconnected to define an interior volume secured to and dimensioned and shaped to fit in a footrest section of a lawn mowing tractor;
• a suction pump, a suction hose, and a spray gun comprising a trigger;
• wherein the suction pump is attached to the first chemical agent tank and is adapted to draw a chemical agent from the chemical agent tank, via the suction hose, and to direct the chemical agent towards the spray gun;
• wherein the lawn mowing tractor comprises a vehicle frame having an upper area and a lower area;
• wherein the upper area has a higher elevation on the vehicle frame than the lower area;
• and
• wherein the footrest section is located on the lower area;
• the lower area including a first slanted wall and a second slanted wall opposite each other that define the footrest section on the vehicle frame, wherein the slanted front panel conforms to the second slanted wall and the slanted rear panel conforms to the first slanted wall, and wherein the bottom panel is parallel to the footrest section such that the chemical agent tank conforms to the specific geometry of the footrest section.
