Ngemva nje kokuqeda izifundo zakhe uGustaf Wrede waya e-United States eyofunda okwengeziwe ngokukhiqizwa kwezimoto. Wasebenzela izinkampani eziningi zezimoto ngo-1911-1912. Phakathi kuka-1912 kuya ku-1914 wasebenza njengoNjiniyela oMkhulu weJackson Automobile Company eMichigan, lapho agxila khona ekufundeni ubuchwepheshe betrekta. Ngo-1914 uWrede wabuyela eFinland futhi waba nguChief Engineer we-Åbo Jernmanufaktur, lapho aqala khona ukuthuthukisa ugandaganda. IMpi Yezwe Yokuqala, eyaqala ngokushesha ngemva kwalokho, yalibambezela umsebenzi wokuthuthukisa; ifektri yamiswa ngokuphelele phakathi neMpi Yombango  <response>: ngo - 1918. Itrektara entsha yagcina yethulwe ekwindla elandelayo. Phakathi naleso sikhathi, iFinland yayisiyimibuso ezimele futhi imakethe evelele yaseRussia yayisivaliwe. Nokho, imakethe yamazwe aseBaltic yayibonakala ithembisa. Ukukhiqizwa kwe-Wrede kwe-tractor okuthiwa i-Kullervo kwaqala ngo-1919. I-Kullervo yayikhiqizwa ngezindlela ezimbili ezinemishini ehlukene. Inguqulo enamandla, engu-30-hp ekuqaleni yayihloselwe ukuthekelisa eRussia. Imodeli encane, enama-hp angu-15 yayiklanyelwe imakethe yasekhaya. Nakuba ukwakhiwa kwakuyisimanje, i-Kullervo ayizange ibe yimpumelelo yokuthengisa; naphezu kwezinsizakalo zikahulumeni, i-American Fordson yabusa imakethe yaseFinland. Ukukhiqizwa kwaphela ngo-1924, kwaze kwaba yilapho sekuthengiswe amayunithi angu-300 kuphela.
