Toro 105-8777-03 Atomic Mower Blade 20.5 Inches

Product Description

The TORO 105-8777-03 is an atomic-style replacement mower blade measuring 20.5 inches in length. Atomic blades are engineered with a secondary cutting edge that mulches grass clippings into finer particles before discharge, reducing clumping and improving lawn appearance. This blade is a direct OEM replacement part sourced from TORO, intended for installation by lawn and garden equipment technicians or experienced equipment operators maintaining TORO walk-behind or self-propelled mowers that accept this blade size.

This blade is suited for residential and light commercial mowing applications where mulching performance is a priority. The 20.5-inch length is specific to TORO mower decks designed around that cutting width. Technicians servicing TORO equipment should verify the deck model number against the parts catalog before installation to confirm fitment. This part is commonly used in seasonal blade replacement programs and routine equipment maintenance.

Key Features

Compatibility

Installation Notes

Blade replacement should be performed by a qualified small-engine or outdoor power equipment technician. Disconnect the spark plug wire before removing or installing any blade to prevent accidental engine startup. Use the appropriate blade removal tool or torque wrench to secure the blade bolt to the manufacturer-specified fastener requirement listed in the equipment service manual.
