Toro 106-3987 Blade Driver Assembly

This is a genuine Toro OEM (Original Equipment Manufacturer) replacement part, ensuring it meets the exact specifications and quality standards of your original equipment.

To confirm compatibility, check your mower's operator manual or the parts diagram for your specific model number. You can also verify the part number stamped on your current blade driver assembly to ensure it matches 106-3987.

You should consider a replacement if you notice excessive vibration, unusual noises during operation, or if the blade no longer spins true. If the assembly shows visible cracks, bent components, or bearing failure, it should be replaced immediately to prevent further damage.

The 106-3987 is the blade driver assembly itself. It does not typically include additional mounting hardware like bolts or washers, so you should retain your existing hardware if it is in good condition.

If you are comfortable with basic mechanical repairs and have the appropriate tools, you can perform this replacement yourself. However, always ensure the spark plug wire is disconnected before working on the mower deck, and consult your service manual for specific torque requirements.
