Abstract: A battery-operated electric hydrostatic utility tractor is disclosed. The utility tractor is a zero-emissions and more capable of powering work attachments to many chores. The tractor frame is supported by ground wheels and is configured to operative couple work accessories. The work accessory has a power connection to couple with an electric source or a pressurized hydraulic fluid carried by the utility tractor. A hydrostatic pump is configured to produce the source of pressurized hydraulic fluid and includes an integrally contained transaxle for selectively providing a hydraulic motive force to a driveshaft for each of an opposed pair of drive wheels. An electric motor has an output axially aligned with an input shaft of the hydrostatic pump, for developing the source of pressurized hydraulic fluid by the hydrostatic pump. A plurality of battery compartments are compartments configured to receive a rechargeable battery to provide the electric source.
