Designed to fit mid-mount zero turn radius mowers, with the appropriate hitch. The hitch allows vac to pivot up and down but not side to side, making the vacuum act like an extension of the mowers frame. Unit is fully castered for easy handling around trees, shrubbery, driveways and other obstacles. The 44 gallon Rubbermaid Brute container is easily removed for quick dumping anywhere: trash pile, pick-up truck, or composter. Comes standard with a 8.75 ft lbs gross torque Briggs and Stratton Intek I/C engine. Optional engines include the Briggs and Stratton 9.0 ft lbs gross torque Intek Pro, Subaru/Robin 6HP, and Honda 5.5HP, engines.
