This part replaces obsolete part #: 594893101 ((for Better Wear When Mulching)) and 139775.

Description:
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.
