With Predator Mulching blades it starts with the steel, featuring a unique steel that incorporates boron, carbon, manganese, and other materials that ensure its strength. The final step in the process is the patented and independently tested Marbain® heat-treating process. This process makes Predator Mulching blades approximately 25% - 40% harder than standard lawnmower blades,making them the longest-lasting, safest and most impact resistant lawnmower blades on the market.

Predator combines the "hump" found in traditional mulching blades with our Predator tooth design producing more airflow and smaller clippings.

Benefits of the Predator Mulching blade:
  • Combines the "hump" found in traditional mulching blades with the Predator tooth design producing more airflow and smaller clippings

Customer Reviews

I have been using the original blades that came with my mower for several years without the bagger; using the deck blocker in the recycle mode. The original blades have done a pretty decent job but lately they've been leaving that little furrow of grass in each row. I decided to get mower blades specifically for mulching. After ordering the blades for my 42" deck, I received a call from the Green Part Store informing me I had ordered the wrong blades that I thought was awesome. It shows how conscientious they are about providing great customer/part satisfaction. I received the correct blades, installed them and cut my grass, about an acre. The grass still happened to be somewhat wet but the blades performed great. I know on dry grass the blades will perform superbly. I’m very happy with these blades to say the least. I’m also sold on the store and how they make sure the customer is taken care of.
