Know before you buy
These blades are specifically designed for Toro TimeCutter zero-turn mowers with a 42-inch deck manufactured from 2007 and newer. Always verify your mower's model number against the OEM part number 131-3939-03 to ensure a perfect fit.
The 3-in-1 design allows you to mulch, bag, or side-discharge grass clippings using the same set of blades. This versatility lets you adapt your mowing style based on the season or the specific needs of your grass.
Genuine OEM Toro parts are engineered to the exact specifications of your mower's deck, ensuring proper balance, airflow, and safety. Using authentic parts helps maintain your mower's performance and longevity compared to generic aftermarket options.
The high-lift cutting edge creates a stronger vacuum effect under the mower deck. This helps stand the grass blades upright before they are cut, resulting in a more uniform finish and improved clipping discharge.
Yes, this 4-pack provides enough blades to fully outfit your 42-inch deck. It is a convenient way to ensure you have a fresh set installed while keeping spares on hand for quick replacements during the mowing season.
