A self-propelled concrete finishing trowel has a power steering system that facilitates operator selection of a desired steering performance response of the trowel. The power steering system includes a controller that communicates operator steering instructions from one or more joysticks and the powered actuators associated with the driven shafts. A selector allows the operator to select one or more preset steering modes, each of which has a different set of steering response characteristics for a given range of joystick motion.
