Multiquip patented the “swing-away upper frame design” that exposes the engine and other internals of the new HHX ride-on trowel for maintenance and repair. The 48-inch trowel uses helical gearboxes and a continuously variable transmission for smooth performance and proportional hydraulic steering reduces operator lever effort. A turbocharged option takes the standard 31-horsepower unit up to 34 horsepower.
