Installation Guide
Before starting installation, ensure the mower is turned off, the spark plug wire is disconnected, and the deck is safely raised or removed. Wear appropriate safety gear, including gloves and eye protection.

- Install New Spindles: Position the new spindle assemblies (GY20050) onto the deck. Secure them using the appropriate mounting bolts. Ensure they are tightened to the manufacturer's specifications.
- Attach New Blades: Install the new blades (GX20249) to the bottom of the spindles. Ensure the cutting edge faces the correct direction for proper mowing. Tighten the blade bolts securely.
- Install Pulleys: Attach the new pulleys (GY20110 and GY20067) to their respective positions. Ensure they are properly aligned.
- Route New Belt: Carefully route the new drive belt (GX20072) around all pulleys according to your mower's diagram. Double-check that the belt is seated correctly in all grooves.

Maintenance
Regular maintenance is essential to extend the life of your mower deck and its components.
- Greasing Spindles: The new spindles are equipped with grease zerks. Apply grease periodically (e.g., every 25 hours of operation or seasonally) to ensure smooth bearing operation and prevent premature wear.
- Blade Inspection: Regularly inspect blades for sharpness, balance, and damage. Sharpen or replace blades as needed to maintain cutting quality and prevent excessive vibration.
- Belt Tension: Check the drive belt tension periodically. A properly tensioned belt ensures efficient power transfer and reduces wear on pulleys and bearings.
- Deck Cleaning: Clean the underside of the mower deck after each use to prevent grass buildup, which can affect cutting performance and lead to corrosion.
