Abstract. Stationary and mobile auxiliary hydraulic circuits were developed for retrofit to an existing hydrostatic circuit for a zero turn radius (ZTR) lawn mower. Both circuits provide remote hydraulic quick connects for attachment of accessory implements powered by the existing ZTR hydraulic pump. The stationary circuit bypasses fluid flow to a wheel motor providing full, reversible pump flow to an auxiliary circuit. The mobile circuit places an accessory motor in series with the wheel motor to provide full, reversible pump flow to an auxiliary circuit. Proof and demonstration of concept were provided with a pull behind log splitter and a rear mounted landscaping blower. The remote hydraulic circuits allow ZTR mowers to serve as as platforms and powerhouses for a number of cylinder- and motor-actuated implement and accessory applications.
