Buying Guide

Match blade to deck size

Confirm blade length and hole pattern match your mower model and deck width to ensure fit and safe operation

Choose blade type by cut style

Mulching blades recirculate clippings for fine mulch, while high-lift or standard blades prioritize discharge or bagging performance

Check OEM compatibility

Select blades labeled compatible with your mower brand (MTD, Cub Cadet, John Deere, etc.) to simplify installation and fit

Consider thickness and steel quality

Thicker, heat-treated steel blades resist bending and hold an edge longer for fewer replacements

Replace in matched sets

For multi-blade decks, replace all blades at once to maintain balance and reduce vibration
