Setup and Installation

This section outlines the steps for replacing a rear wheel on compatible Toro FWD Recycler Lawn Mowers.

1. Prepare the Mower: Ensure the mower is on a flat, stable surface. Disconnect the spark plug wire to prevent accidental starting.
2. Remove Old Wheel: Locate the retaining bolt or nut securing the existing rear wheel. Use an appropriate wrench or socket to loosen and remove it. Carefully pull the old wheel off the axle.
3. Inspect Axle: Clean any debris from the axle and surrounding area. Inspect the axle for any damage or wear.
4. Install New Wheel: Align the new Toro Genuine OEM Rear Wheel (Part No. 140-2351) onto the axle. Ensure the wheel is seated correctly and fully engaged with any drive gears or splines if applicable for FWD models.
5. Secure Wheel: Reinstall the retaining bolt or nut. Tighten securely, but do not overtighten.
6. Test: Gently spin the wheel to ensure it rotates freely. Reconnect the spark plug wire.

Operating Considerations

Once installed, the new rear wheel operates as part of your mower's drive system. The skid-resistant tread is designed to provide optimal traction during mowing operations, especially for front-wheel drive models.

Maintenance

Regular maintenance ensures the longevity and performance of your rear wheel.

• Cleaning: Periodically clean grass clippings and debris from around the wheel and axle area. This prevents buildup that could impede rotation or damage components.
• Inspection: Regularly inspect the wheel for signs of wear, cracks, or damage to the tread. Check for any looseness in the axle connection.
• Lubrication: Consult your mower's specific manual for any recommended lubrication points around the wheel axle or bearings.

Troubleshooting

If you encounter issues with your new rear wheel, consider the following:

• Wheel Not Turning Freely: Check for debris wrapped around the axle or inside the wheel hub. Ensure the retaining bolt/nut is not overtightened.
• Loss of Traction: Inspect the tread for excessive wear or damage. Ensure the wheel is properly engaged with the mower's drive system (if applicable for FWD models).
• Unusual Noise: This could indicate a loose wheel, worn bearing (if applicable), or debris. Disconnect spark plug, inspect, and re-secure.

If problems persist, contact a certified Toro service technician.
