The PRO446DF from Allen Engineering is a high-performance 46-inch walk-behind concrete trowel engineered for large-scale slab finishing and the most demanding job-site conditions. Built for professional contractors who require reliability, power, and consistency, the PRO446DF delivers superior torque and finishing control with its heavy-duty Duromax XP18HPX engine and direct-drive system. Whether you’re pouring commercial floors, industrial pads, or exterior flatwork, this machine brings professional-grade performance to every pass.
Designed as part of Allen’s rugged Pro Series, the PRO446DF blends exceptional strength and finishing finesse—making it one of the most powerful and efficient walk-behind trowels available in its class.
Duromax Engine and Direct Drive for Maximum Power
At the core of the PRO446DF is the 18-hp class Duromax XP18HPX engine, chosen for its outstanding output, reliability, and longevity. Paired with a direct-drive system, this setup maximizes torque transfer to the rotor, reducing maintenance and improving responsiveness. Unlike belt-driven alternatives, this concrete trowel ensures minimal power loss, making it ideal for difficult mixes, extended finishing sessions, and high-production jobsites.
Its 46-inch rotor delivers broad surface coverage while maintaining balance and maneuverability, allowing contractors to cover more ground with fewer passes and reduced fatigue.
Pro Series Control and Operator Comfort
As with all Allen Pro Series trowels, the PRO446DF is equipped with ergonomic features that prioritize operator comfort and efficiency. The Rapid Pitch handle system allows for quick and intuitive blade pitch adjustments during operation, giving finishers complete control over the finish—from float to final pass.
The handle is vibration-dampened to minimize operator fatigue, making the concrete finishing machine easier to operate over long shifts. A built-in lifting hook ensures simple transport and setup, further streamlining jobsite logistics.
Built Tough for Daily Commercial Use
The PRO446DF features a heavy-duty steel frame and reinforced rotor assembly, designed to withstand the constant rigors of large-scale commercial concrete work. From open slab pours to tough finishing zones, this machine is ready to take on daily abuse while maintaining consistent, top-tier results.
