COMMERCIAL VS. PRO TROWELS – WHAT’S THE DIFFERENCE?

Bartell manufactures two lines of Power Trowels: Commercial and Pro Series. Both are available in 36-inch and 46-inch sizes and handle the same finishing tasks, but they differ in key performance and design elements:

• Chrome vs. Painted Ring: The Pro Series includes a chrome ring for enhanced durability and aesthetics, while the Commercial Series features a painted ring.
• Ride-On vs. Walk-Behind Gearbox: The Pro Series integrates a ride-on trowel gearbox for increased power and longevity, compared to the walk-behind gearbox in the Commercial Series.
• Spider Assembly Build: Both lines use precision manufacturing for their spider assemblies, ensuring efficient, high-tolerance troweling.
• Warranty Duration: The Pro Series includes a 3-year warranty, whereas the Commercial Series offers a 1-year warranty.

While both offer robust performance and quality construction, the Pro Series stands apart with the industry’s only walk-behind trowel using a ride-on gearbox—delivering unmatched power and durability.
