The Genuine Factory Parts 42" Ultra High-Lift Blade Set is for when you need even more lift when you are bagging or side discharging. The blade edges are designed to create a higher-lifting airflow that propels more clippings into the bags and leave fewer clippings behind. Genuine Factory Part blades are original equipment blades for CRAFTSMAN, CUB CADET and TROY-BILT. Designed for precise fit and optimal performance, you can have confidence that they are going to provide you the cutting performance you need and expect from your rider and zero turn mower.
