Manually Operated Sulkies
Two-wheeled manual sulkies were developed in the 1970s for use in the tropics by forest development projects of mainly Scandinavian countries. In its final development stage, a sulky with double bogie wheels was designed in 1985 in Finland and applied widely in east African countries and the Philippines under the FINNIDA APPRODEV project.
