Toro 133-2157 Atomic Rotary Blade 20.5 Inches

Product Description

The TORO 133-2157 is an Atomic rotary mower blade measuring 20.5 inches in length, designed as a direct OEM replacement for compatible TORO walk-behind and self-propelled rotary mowers. Atomic-style blades are engineered with a high-lift wing geometry that increases airflow beneath the deck, promoting cleaner cuts and improved grass discharge or mulching performance. This blade is installed and serviced by lawn equipment technicians and knowledgeable equipment operators performing routine seasonal maintenance or blade replacement after impact damage.

This blade is suited for residential rotary mower applications where the 20.5-inch deck configuration is specified. Atomic blades perform well in both standard discharge and mulching setups, making them a versatile replacement option for equipment maintained on a regular service schedule. Consult your mower's operator manual to confirm deck size and blade fitment before installation.

Installation Notes

Blade replacement should be performed by a qualified service technician or experienced equipment operator. Always disconnect the spark plug wire before servicing the blade to prevent accidental engine startup. Use a torque wrench and follow the mower manufacturer's fastener specifications in the service manual when securing the blade bolt.
