The Genuine Factory Parts 30" 3-in-1 Blade is designed to provide a great looking cut whether you are bagging, mulching or side discharging. Mowing on dull, worn blades can rip and tear the tips of the grass and leave your grass vulnerable to disease and browning. 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 riding mower.
