The Bartell B446 Pro Series Trowel has earned a strong reputation among concrete professionals worldwide for its exceptional quality, durability, and balanced performance. Its proven gearbox and spider assembly design has remained largely unchanged for more than 70 years, demonstrating its reliability and long-term performance. Bartell backs the B446 with a 3-year warranty, providing one of the strongest walk-behind trowel warranties in the industry.
Available in 36-inch and 46-inch models, each trowel is built with heavy-gauge steel and precision jig-welded construction for maximum strength, rigidity, and durability.
The gearbox and spider assembly are key features that set the Bartell Pro Series apart. The precision-machined aluminum gearbox is equipped with heavy-duty bronze and steel worm gears for dependable operation. The spider assembly is engineered with precisely matched tolerances between the hub and arms to minimize flex and maintain consistent blade pressure.
This rigid design keeps the blades firmly engaged with the concrete surface, helping eliminate high spots quickly and produce a smoother, more consistent finish. The result is excellent productivity, dependable performance, and professional-quality concrete finishes.
