What One Purchase Includes
One blade. A multi-blade deck may require more than one; order the quantity required for your exact deck.
Fitment Safeguard
Do not order from dimensions or appearance alone. Verify the complete OEM or replacement number, mower or engine model, serial range, deck size, mounting pattern, and required quantity. Similar-looking parts can differ in offset, rotation, hole pattern, connector, thread, or other critical details.
Installation and Service
No product-specific installation manual was verified in the supplier record. Follow the equipment manufacturer's service procedure. For blades, stop the engine, remove the key, disconnect the spark-plug lead, block the blade, wear cut-resistant gloves, install in the correct orientation, and torque the fastener to the equipment manufacturer's specification. Replace damaged hardware and verify free rotation before use.
