Description

Allen Engineering PRO446: Power, Precision, and Durability

Built for Demanding Concrete Finishing

The PRO446 from Allen Engineering is a heavy-duty walk-behind concrete trowel designed for contractors who need strength, control, and consistency. As part of Allen’s Pro Series lineup of trowels, the PRO446 combines a 46-inch rotor with a rugged Honda GX270 engine, giving crews the coverage and torque required for large slab applications. From commercial floors to expansive flatwork, this machine delivers smooth and uniform results every time.

Honda Power for Reliable Performance

At the core of the PRO446 is the proven Honda GX270 engine, trusted for its durability, quiet operation, and fuel efficiency. This powerhouse provides steady torque and responsiveness throughout the finishing process, whether floating early or executing final passes. Paired with a direct-drive gearbox, the engine ensures maximum power transfer with less maintenance compared to belt-driven units, making the PRO446 a dependable concrete finishing machine for high-production crews.

Operator Comfort and Control

Allen designed the PRO446 with the operator in mind. Crews can choose between Fine Pitch or Rapid Pitch handle systems, allowing for customizable blade adjustment to match specific job needs. The ergonomic handle reduces vibration and fatigue during long pours, while a built-in lifting hook makes transport easy. With its 46-inch rotor, this concrete trowel balances precision around rebar and fixtures with the coverage needed for large-scale pours.

Durability Contractors Can Trust

Like all Allen trowels, the PRO446 is built to last. Its heavy-duty steel frame, rugged rotor assembly, and industrial-grade components withstand daily job demands. Contractors gain a long-term investment that delivers consistent performance pour after pour, ensuring maximum value and reliability.
