MSP455: High-Performance Finishing with Fuel-Efficient EFI Power

The MSP455 from Allen Engineering is a powerful and efficient ride-on trowel machine built to handle high-production concrete finishing with unmatched precision. Engineered for durability and control, this machine features a fuel-injected EFI engine that delivers superior fuel economy, smooth throttle response, and reliable performance under demanding jobsite conditions. Whether you’re floating or finishing, the MSP455 provides the torque, coverage, and control needed to consistently produce high-quality results.

Ideal for commercial and industrial slab applications, the MSP455 combines modern engine technology with Allen’s legacy of tough, jobsite-ready construction. It’s an essential tool in any contractor’s fleet of professional trowels.

Fuel-Injected Power for Maximum Efficiency

At the core of the MSP455 is a reliable EFI (Electronic Fuel Injection) engine. This advanced power plant adjusts fuel delivery in real time to match working conditions, optimizing fuel consumption and delivering reliable starts regardless of temperature or altitude. The EFI system reduces downtime and maintenance while improving throttle response and consistency across the entire slab.

With high torque output, the EFI engine allows the MSP455 to perform exceptionally well during both floating and final finish passes, delivering superior results across various concrete conditions.

Smooth, Responsive, and Built for Productivity

The MSP455 features dual five-blade rotors designed for wider coverage and enhanced finish quality. This layout maximizes surface area contact, reducing the number of passes needed to complete a slab. Precision steering and ergonomic controls make the MSP455 highly maneuverable, while its balanced weight distribution ensures consistent pressure and a smoother ride across large surfaces.

As a concrete finishing machine, it’s built for operators who spend long days on the slab—offering comfort and efficiency without compromising power or slab quality.

Engineered for the Toughest Jobsites

Backed by Allen’s industry-leading reputation for durability, the MSP455 is built with a heavy-duty frame, high-capacity gearbox, and reinforced rotor assemblies. It’s a jobsite-tough concrete trowel that’s ready to perform pour after pour.
