Workers manufacturing lawnmowers at the Jacobsen Manufacturing Company of Racine, Wisconsin. Assembling blades and wheels. Testing the sharpness of the blades by holding a piece of paper up to them. A finish or paint is applied with a blower. Infrared lamps dry the hanging lawnmowers. Decals are applied. The engines are tested at the end as well as headlamps for “night mowing”. Finally a man mowing his front lawn on a sunny day.
