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.
