Mower Blades
Replacement Mower Blades
Shop replacement mower blades for riding mowers, zero-turn mowers, and lawn tractors. Mower blades are one of the most important deck parts for cut quality, discharge performance, and overall mower deck efficiency.
Blades are commonly replaced when they are bent, dull, cracked, worn thin, leaving strips of uncut grass, causing vibration, or producing poor cut quality even after sharpening.
Find mower blades for popular brands including Craftsman, Husqvarna, Poulan, John Deere, Cub Cadet, MTD, Toro, Ariens, Gravely, and more.
Before Ordering Mower Blades
Important: Match your original blade part number whenever possible, then confirm blade length, center hole style, width, thickness, lift style, deck size, and mower model before ordering.
- Confirm your mower model number
- Confirm your deck size
- Match the original blade part number when possible
- Confirm blade length
- Confirm center hole style, such as 5-point star, 6-point star, round, or bow-tie
- Confirm blade width and thickness
- Confirm whether you need standard lift, high lift, mulching, or bagging blades
- Inspect spindle assemblies, blade bolts, washers, and deck belt condition before installation
Common Signs You Need New Mower Blades
- Uneven cut quality
- Strips of uncut grass
- Grass tips look torn instead of cleanly cut
- Deck vibration after blade engagement
- Blade is bent, cracked, chipped, or worn thin
- Poor discharge or clumping
- Blade cannot be safely sharpened again
- Visible impact damage from rocks, roots, or debris
Blade Fitment Tips
Many mower blades look similar but are not interchangeable. A blade with the wrong length, center hole, lift profile, or mounting style can hit the deck shell, create vibration, reduce cut quality, or damage the spindle assembly.
If your mower uses a multi-blade deck, replace blades as a matched set whenever possible. Mixing old and new blades, or mixing different blade styles, can cause uneven airflow and poor cut quality.
Related Deck Parts
Mower blades often wear alongside other deck parts. If your mower is vibrating, cutting unevenly, or damaging belts, inspect the spindle assemblies, spindle pulleys, idler pulleys, deck belt, blade bolts, and belt routing before installing new blades.
