Description

Allen Engineering PRO436TC: Unmatched Speed and Precision

Built for Professional Concrete Finishing

The PRO436TC from Allen Engineering is a 36-inch walk-behind concrete trowel built for contractors who demand speed, precision, and adaptability. As part of the Allen Pro Series, the PRO436TC introduces a variable-speed torque converter clutch that outperforms traditional centrifugal systems found in standard trowels. This innovation provides an expanded rotor speed range and consistent torque delivery, giving finishers unmatched control from floating to final passes.

Variable-Speed Clutch Advantage

What makes the PRO436TC stand out is its torque converter clutch. Operators can seamlessly adjust rotor speeds while maintaining strong torque, which allows them to adapt instantly to changing slab conditions. Whether you’re early-stage floating or finishing for maximum smoothness, this system ensures superior handling, faster coverage, and improved finish quality. Contractors save time while maintaining the precision expected from a professional-grade concrete finishing machine.

Powered by Honda Performance

At the core of the PRO436TC is the proven Honda GX270 engine. Known for its reliability, fuel efficiency, and smooth operation, this powerhouse drives the 36-inch rotor with consistent performance. Combined with a direct-drive gearbox, it minimizes power loss while reducing maintenance requirements. Built with heavy-duty components and a rugged frame, the PRO436TC withstands tough jobsite conditions day after day.

Operator Comfort and Control

Like all Allen trowels, this model prioritizes operator ease. The ergonomic Rapid Pitch handle system allows quick and precise blade pitch adjustments, while its balanced design reduces vibration and fatigue. This combination gives operators better comfort during long pours and more consistent results across medium-sized slabs.
