Buying Guide

Match blade to deck size

Confirm blade length and hole pattern match your mower's deck and spindle before purchase to ensure proper fit and balance

Choose blade type for your mowing style

Mulching blades recut clippings for finer discharge while standard/high-lift blades prioritize bagging or side discharge

Check brand compatibility

Replacement blades from MaxPower, MTD, Oregon, and OEM-compatible listings often note fit for MTD, Cub Cadet, John Deere, Husqvarna, and similar brands

Look for reinforced construction

Heat-treated steel, sharpened cutting edges, and balanced sets reduce vibration and extend service life

Consider included hardware

Blade adapter kits or starter hardware simplify installation on mowers that require specific mounts or spacers
