A battery powered driver for propelling a wheeled ground surface modifying machine includes at least one wheel contacting a ground surface, a battery powered electric motor, control circuitry configured to manage delivery of electrical battery power to the electric motor to control a sped of the driver, at least one pedal attached to a pedal axle and tiltable in each of a forward and rearward direction with respect to the pedal axle, and at least one pedal tilt sensor configured to output one or more signals to the control circuitry indicating a degree of tilt of the at least one pedal. The control circuitry is configured to control the electric motor to accelerate the driver forward based on the one or more signals indicating a forward tilt of the at least one pedal, the electrical battery power delivered to the electric motor for forward acceleration proportional to a degree of forward tilt of the at least one pedal, and to control the electric motor to accelerate the driver rearward based on the one or more signals indicating a rearward tilt of at least one pedal, the electrical battery power delivered to the electric motor for rearward acceleration proportional to a degree of rearward tilt of the at least one pedal.
