The company dates back to 1974, when Risto Hartzell began excavator contracting. As operations grew and over the years, the company's name changed to Hartzell Oy and brothers Jari and Janne took over responsibility for operations. Over time, earthworks decreased and the emphasis on the earthmoving side intensified. Under the same roof, we offer both ground driving and deliveries from aggregates to mold and shell roofs.
