Model 452 is designed to fit standard lawn and garden tractors without any special hitching mechanism. A chain lock system does not allow vacuum to pivot to the right or left once attached, making the vacuum act like an extension of the frame on the tractor. The 452 is fully castered for easy handling around trees, shrubbery, driveways and other obstacles and powered by a 6.5HP Briggs and Stratton Intek I/C engine.
