The 452 model is powered by the FX200 Champ engine and the air turbine for maximum air flow and pickup efficiency of grass clippings, leaves and light litter from mower discharge. 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 spring-loaded top assembly lifts quickly out of the way with minimum effort. The versatile Model 452 Trac-Vac is quick, quiet and clean to operate. Optional engines include the Champ Pro+ engine with the 1” crankshaft and an electric start FX200E Champ option too! The model 452 has a 6" hose, recommended for deck sizes 54" or less.
