With models ranging from edging, standard, high-horsepower and variable-speed units, concrete finishers can find the size and power of a walk-behind trowel to fit any job. The CT 24-4A is designed for up to the edge finishing, offering better floating and finishing capabilities along wall lines and obstacles, improving productivity and quality. CT 36-5A and CT 36-6 are 36-in.-diameter models that offer the choice of a 5.5- or 5.6-hp engine. The CT 48-8A and CT 48-9 are 48-inch diameter models with the choice of an 8- or 9-hp engine. CT 36-8A, CT 36-9, and CT 48-11A models offer a higher horsepower option, which provide better torque for low-speed floating and additional weight for those operators who prefer a heavier trowel. CT 36-8A-V, CT 36-9V, and CT 48-13A-V offer a variable transmission system that provides wide speed range for low-speed, high-torque floating through a high-speed burnishing machine.
