A power trowel (also known as a "power float", "helicopter" or "trowel machine" or "whirlybird") is a piece of light construction equipment used by construction companies and contractors, to apply a smooth finish to concrete slabs. ==Types== Power trowels differ in the way they are controlled: *Ride-on power trowels are used by an operator sitting on a seat upon the machinery, controlling the power trowel with the necessary buttons. *Walk-behind power trowels are used by an operator walking behind the machine. A hand tool for the same task is called a concrete float. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Power trowel」の詳細全文を読む スポンサード リンク
