RIDING TYPE CONCRETE TROWEL HAVING STABLE MECHANISM

摘要

PPROBLEM TO BE SOLVED: To solve the problem of being conventionally difficult to reduce vibration generated in a riding type finishing trowel. PSOLUTION: This riding type concrete finishing trowel restrains vibration of a rotor assembly of the trowel by arranging a stable mechanism between a gear box or a constituting part joined to this gear box and a frame. The stable mechanism is formed of a gas spring arranged between the frame and a pitch control post. The gas spring is desirably arranged in close vicinity to a top part of the pitch control post.
