The History of Power Trowels
The power trowel, also known as a power float or helicopter, is a construction tool that is used to create a smooth surface on concrete. It is a modern innovation that has greatly improved the efficiency and quality of concrete finishing.
Early Concrete Finishing Tools
Before the invention of power trowels, concrete finishing was a labor-intensive process that required the use of manual tools such as hand trowels and wooden floats. These tools were effective but required a lot of physical effort and time to achieve a smooth finish.
In the early 1900s, the introduction of mechanical tools such as screeds and hand floats made the concrete finishing process more efficient. These tools reduced the physical effort required to finish large concrete surfaces, but they still required skilled operators and were not suitable for all types of concrete finishes.
The Invention of the Power Trowel
The power trowel as we know it today was invented by a man named Marshalltown Company in Marshalltown, Iowa, in the early 1930s. The company recognized the need for a more efficient and versatile tool for concrete finishing and developed the first power trowel.
The early power trowels were gasoline-powered and operated by a single person. They featured rotating blades or discs that would smooth the concrete surface as the operator pushed the machine forward. This significantly reduced the time and effort required to achieve a smooth finish on concrete.
Over the years, the design of power trowels has been improved and refined. Today, there are various types of power trowels available, including walk-behind and ride-on models. These trowels have become an essential tool in the construction industry, allowing for faster and more precise concrete finishing.
The Impact of Power Trowels
The invention of the power trowel revolutionized the concrete finishing industry. It not only significantly reduced the time and effort required to finish concrete surfaces but also improved the quality and uniformity of finishes. This led to increased productivity in the construction industry and allowed for the completion of projects in a shorter time frame.
Power trowels have become a staple tool in the construction industry and are used in a wide range of projects, from residential driveways to large-scale commercial buildings. They have made concrete finishing more accessible and efficient, helping to create smoother, more durable, and visually appealing concrete surfaces.

The Invention of Power Trowels
The power trowel, also known as a power float or helicopter, was invented in the early 20th century to streamline the process of finishing concrete surfaces. Before the advent of power trowels, finishing concrete was a labor-intensive task that required a team of workers using manual tools.
The credit for inventing the power trowel goes to a man named Joseph Lennox Wauhob. Wauhob, an American engineer and inventor, developed the first power trowel in 1937. His invention revolutionized the construction industry by significantly reducing the time and effort required to finish concrete surfaces.
Prior to Wauhob’s invention, workers would use hand trowels and other manual tools to smooth and level freshly poured concrete. This process was not only time-consuming but also physically demanding. The introduction of power trowels allowed for a more efficient and effective way of achieving smooth and polished concrete surfaces.
Wauhob’s power trowel consisted of a gasoline engine mounted on a frame, with spinning blades attached to the bottom. The machine’s blades would rotate rapidly, allowing the operator to effortlessly maneuver the power trowel over the concrete surface, smoothing and leveling it in the process. This eliminated the need for strenuous manual labor and greatly accelerated the finishing process.
Since Wauhob’s invention, power trowels have undergone various improvements and refinements, but the basic principles and design remain the same. Today, power trowels are indispensable tools in the construction industry, used for finishing concrete floors, driveways, and other large paved surfaces.
The invention of power trowels has not only improved the efficiency of concrete finishing but has also contributed to the advancement of modern construction techniques. Thanks to this invention, construction projects can be completed more quickly and with higher quality results.
Early Development of Power Trowels
The invention of the power trowel revolutionized the construction industry, making it easier and more efficient to finish concrete surfaces. The early development of power trowels can be traced back to the early 20th century.
In 1939, a man named Joseph Steinberg filed a patent for a machine designed to finish concrete surfaces. His invention consisted of a motorized buggy equipped with rotating blades that smoothed and polished the surface. This early design laid the foundation for the modern power trowel.
During World War II, there was a high demand for airstrips, which required large areas of concrete to be finished quickly. This demand spurred further development of power trowels, leading to the creation of machines specifically designed for finishing concrete. These early power trowels were often towed behind tractors and featured adjustable blades to control the depth and finish of the concrete surface.
In the 1950s, a man named Allen Alkema further improved the design of the power trowel. He introduced a walk-behind model that allowed operators to have more control and maneuverability. This design became popular among contractors and is still widely used today.
Over the years, power trowels have continued to evolve and improve. Modern power trowels are equipped with more advanced features, such as variable speed controls and ergonomic handles, to further enhance productivity and user comfort.
The early development of power trowels paved the way for the efficient and precise finishing of concrete surfaces. Today, power trowels are an essential tool in the construction industry, allowing for the creation of high-quality, smooth, and durable concrete floors and pavements.
