PRO446TC: Precision Speed Control for High-Output Concrete Finishing
The PRO446TC from Allen Engineering is a premium 46-inch walk-behind concrete trowel built for contractors who demand both power and precise speed control in large slab applications. As part of the trusted Allen Pro Series, the PRO446TC blends advanced clutch technology with rugged construction to deliver a concrete finishing machine that’s built for performance, durability, and adaptability on today’s busiest jobsites.
Powered by the robust and reliable Honda GX390 engine, the PRO446TC stands out with its variable-speed torque converter clutch—an innovation that replaces the traditional centrifugal clutch found in standard trowels. This advanced clutch system allows for a broader range of rotor speeds, enabling the operator to fine-tune torque and speed throughout every stage of the finishing process.
Torque Converter Technology for Maximum Control
What makes the PRO446TC truly exceptional is its torque converter clutch, which gives contractors the ability to seamlessly transition between floating and finishing with greater speed precision. Unlike fixed-speed centrifugal clutches, this system provides more flexibility, making it ideal for a wide range of concrete conditions, weather changes, and jobsite demands.
Whether you’re applying early floats or final finishing passes, this concrete trowel keeps power consistent and under your complete control. The ability to adjust rotor speed on the fly enhances slab flatness, reduces labor, and increases productivity.
Honda GX390 Power and Pro Series Durability
The PRO446TC features the field-proven Honda GX390 engine, delivering strong, consistent power and long-term reliability. Its 46-inch rotor diameter offers excellent surface coverage, making it perfect for medium to large slab pours. With a direct-drive gearbox, the concrete finishing machine ensures minimal power loss while eliminating belt maintenance issues.
Designed for extended operation, this walk-behind concrete trowel features Allen’s ergonomic Rapid Pitch handle system for quick and intuitive blade pitch adjustments. The heavy-duty frame, vibration-dampening grips, and included lifting hook further reinforce its role as a true jobsite workhorse.
