HUSQVARNA CRT 48 57K-PS 

The Husqvarna CRT 48 PS with power steering achieves high productivity with excellent results thanks to its optimal maneuverability and high surface capacity as well as a balanced power-to-weight ratio. CRT 48 PS is ideal to finish surfaces from 10,000 sq ft up to 25,000 sq ft. The electro-hydraulic joystick control enables accurate maneuvering and virtually fatigue-free operation. Controlled by joystick modulations, the valves of the hydraulic control cylinder are triggered by electrical signals. CRT 48 PS offers a choice of two control modes to accommodate operator preference in varying site conditions.
