This authentic replacement part is made for use with riding lawn mowers/tractors. Mulching blades are designed to keep the grass under the deck longer. That way it will be cut into smaller pieces, providing better mulch that will decompose quicker. This blade has a star shaped opening that helps to secure the blade. Includes one (1) blade per order.
You would need a wrench to replace this blade.

The mulching blades I ordered fit perfectly.
I had purchased 2 sets of mulching blades locally which did not fit.
Your delivery company (FEDEX) has a poor record for delivery to me.
My order was delivered 4 or 5 days past the order estimated delivery date.

Remove belt,drop deck and remove, remove pulley, remove four bolts, mandrel assembly will come right out. Reverse procedure to replace with new parts. I had to Google the owners manual to find the belt diagram as my belt had broken and I couldn't read the diagram on the deck. It took a bit more than 30 minutes total.
