4. Setup and Installation
The following are general steps for replacing a lawn mower wheel. Specific procedures may vary depending on your mower model. Refer to your mower's owner's manual for detailed instructions.
- Prepare the Mower:
- Ensure the engine is cool.
- Disconnect the spark plug wire to prevent accidental starting.
- If the mower has a fuel tank, ensure it is less than half full and tilt the mower so the carburetor side is facing up to prevent fuel leakage.
- Securely prop the mower on a stable surface, ensuring the wheel to be replaced is accessible and the mower cannot tip over.
- Remove the Old Wheel:
- Locate the retaining bolt or nut that secures the wheel to the axle. This may be covered by a hubcap or dust cover.
- Use an appropriate wrench or socket to loosen and remove the bolt/nut.
- Carefully slide the old wheel off the axle. Note the position of any washers or spacers.
- Install the New Wheel:
- Ensure the axle is clean and free of debris.
- Align the new Toro RWD Rear Drive Wheel (Part 138-3216) with the axle. Ensure any washers or spacers are correctly positioned as they were on the old wheel.
- Slide the new wheel onto the axle.
- Reinstall the retaining bolt or nut. Tighten it securely, but do not overtighten, as this can damage the wheel or axle.
- Test the Installation:
- Gently spin the newly installed wheel to ensure it rotates freely without binding.
- Lower the mower back to its operating position.
- Reconnect the spark plug wire.
- Briefly operate the mower to confirm proper wheel function and traction.
If you encounter any difficulties, consult a qualified service technician or refer to your mower's detailed service manual.
5. Operating Considerations
These RWD Rear Drive Wheels are designed to provide effective traction for your self-propelled Toro lawn mower. Proper operation of your mower, including maintaining appropriate ground speed and avoiding obstacles, will contribute to the longevity and performance of these wheels.
- Traction: The skid-resistant tread pattern is designed to maximize grip on various lawn surfaces.
- Maneuverability: Ensure wheels are free of debris to allow for smooth turning and movement.
- Even Wear: Operating the mower on relatively flat surfaces and avoiding excessive turns in one direction can help promote even wear across both rear wheels.
6. Maintenance
Regular maintenance of your lawn mower's wheels can extend their lifespan and ensure continued optimal performance.
- Regular Cleaning: After each use, clean any grass clippings, dirt, or debris from around the wheels and axles. Accumulated debris can hinder rotation and cause premature wear.
- Inspect for Wear: Periodically inspect the wheel treads for signs of excessive wear, cracks, or damage. Worn treads can reduce traction.
- Check for Play: Check if the wheels have excessive side-to-side play on the axle. If so, ensure the retaining bolt/nut is tight. If play persists, inspect the axle or wheel hub for wear.
- Lubrication (if applicable): Some mower axles may benefit from light lubrication. Consult your mower's manual for specific lubrication recommendations for the wheel axles. Avoid lubricating the wheel tread.
- Storage: When storing the mower for extended periods, ensure the wheels are clean and dry.
