A work vehicle transaxle arrangement includes a main shaft; at least one transaxle gear assembly; a differential drive shaft; a first electric machine configured to drive rotation of the differential drive shaft such that mechanical power is distributed through the differential to the axle half-shafts; a second electric machine; a PTO shaft; and a hydraulic pump. In a hybrid configuration, the main shaft is configured to be driven by an internal combustion engine to power the PTO shaft and the second electric machine such that the second electric machine generates electrical power routed through the inverter to at least partially drive the first electric machine; and in an electric-only configuration, the second electric machine is driven by electrical power routed through the inverter and drawn from the battery to generate mechanical power that drives the PTO shaft and the hydraulic pump through the at least one transaxle gear assembly.
