A light-weight portable hydraulic system for engagement with equipment requiring hydraulic fluid to operate. The system includes a reservoir a pump and an oil filter engaged with each other. One or more handles are provided on the system so that the system may be carried by a single individual or may be lifted onto or off of a supporting unit upon which the system is mountable. A suitable supporting unit may be a zero-turn stand-on mower. An input shaft for the pump is operatively engaged with the engine of the mower and the pump is powered by that engine. The system is selectively connected to the equipment requiring hydraulic fluid for operation, such as a mower attachment, by way of hydraulic hoses that quick connect to ports on the pump. The system may be engaged with or disengaged from the mower in around thirty seconds and without tools.
