To install the Toro 104-0640 Blade Kit, first ensure the mower is turned off and the spark plug is disconnected. Remove the existing blade by loosening the mounting bolt with a wrench. Attach the new blade from the kit, ensuring the cutting edge is facing the correct direction. Tighten the bolt securely and reconnect the spark plug.
If the blades are not cutting evenly, check for any obstructions or debris stuck to the blades. Ensure the blades are properly balanced and securely installed. It's also important to verify that the mower deck is level. Sharpen or replace the blades if they are dull or damaged.
Blades should be sharpened after approximately every 25 hours of use, or whenever you notice a decline in cutting performance. Regularly inspect the blades for sharpness and damage, and sharpen them as needed to maintain optimal cutting efficiency.
While it is possible to use the Toro 104-0640 Blade Kit on wet grass, it is not recommended. Wet grass can clump and stick to the mower deck, leading to uneven cuts and potential clogging. For best results, mow when the grass is dry.
To clean the blades after use, ensure the mower is turned off and the spark plug is disconnected. Use a brush or cloth to remove grass clippings and debris. For stubborn residue, a mild detergent with water can be used. Dry the blades thoroughly to prevent rusting.
Replace the blades when they are excessively worn, cracked, or damaged beyond repair. If sharpening no longer improves cutting performance, it's time for a replacement. Regular inspection can prevent unexpected issues during use.
Always wear protective gloves when handling mower blades to prevent cuts. Ensure the mower is turned off and the spark plug is disconnected before performing any maintenance. Use proper tools to avoid injury and make sure the blades are securely mounted.
The Toro 104-0640 Blade Kit is designed for specific Toro models. Refer to the product manual or Toro's official website to ensure compatibility with your mower model before purchasing or installing the kit.
Signs of a dull blade include uneven grass cuts, torn or bruised grass tips, and increased engine workload. If the mower leaves behind uncut patches or the grass appears frayed, the blades likely need sharpening.
To balance the blades, remove them from the mower and clean off any dirt. Place the center hole of the blade onto a blade balancer or a nail. If one side dips, remove material from the heavier side until the blade remains level. Proper balancing ensures a smooth cut and reduces mower vibration.
