A kit for retrofitting a vehicle, such as a lawn mower or tractor, into a lawn care vehicle for distributing liquids for treatment of a lawn, the kit includes a base, a liquid tank, a hose reel, and a fluid flow control system. The fluid flow control system includes a dispensing hose on the hose reel and a hand-held hose. A Y-shape valve fluidically connects the dispensing hose and the hand-held hose to each other and to the liquid tank. The nozzles of the dispensing hose and the hand-held hose have a magnet so as to magnetically mount them anywhere on the vehicle, and the components of the kit may be mounted in various arrangements on the vehicle.
