Description

Made for compatible John Deere 42-inch mower decks, M170642 Mulching blades support clean, consistent cutting during routine lawn care. Replacing OEM part numbers M170642 and UC22008, this 2-blade set is designed for select John Deere riding and zero-turn mowers.

The blades are precision made from premium, high strength steel designed to hold a stable cutting edge and provide long lasting performance in the most demanding mowing conditions. Each blade arrives pre-sharpened with safety paint that wears off during initial operation, and the cutting edge can be safely resharpened when it becomes dull. All compatible lawn mower models are listed below.

This Mulching kit is a dependable replacement for worn or damaged blades that helps restore cutting performance on compatible 42-inch decks. Before ordering, verify your mower's complete model number, deck size, and original OEM blade number.

If you are unsure of compatibility, please cross reference your original blade number or mower model before ordering.

How often should I sharpen my lawn mower blades?

Are these mulching blades or standard blades?

These are Mulching blades designed for compatible 42-inch mower decks. The package includes two blades with a Circle (13/16") center hole.

Why does my mower leave grass looking ragged after cutting?
