A lawn care vehicle or truck has a 24 volt auxiliary battery supply connected to operate an electric motor driven hydraulic pump connected to operate a hydraulic motor which drives a liquid chemical distributing pump in a line extending from a liquid supply tank to a flexible hose extending from a hose reel. The auxiliary battery supply is connected to the 12 volt truck battery through a voltage converter for recharging by the battery charger driven by the truck engine. When the truck arrives at a lawn care site, the truck engine is shut down, and the liquid distributing pump is operated by the auxiliary battery supply. The electric motor driven hydraulic pump is also connected to a hydraulic motor coupled to rotate the hose reel. A 110 volt battery charger connects with the voltage converter for recharging the auxiliary battery supply when the truck is not in use.
