Setup and Installation
Proper installation of the rear drive wheels is crucial for the safe and efficient operation of your lawn mower. Refer to your specific mower's service manual for detailed instructions on accessing the drive axle and removing old wheels.
Tools Required:
- Wrench or socket set (appropriate size for axle nuts)
- Gloves (recommended)
- Cleaning cloth
Installation Steps:
- Prepare the Mower: Ensure the lawn mower is turned off, the spark plug wire is disconnected (for gasoline models), or the battery is removed (for electric/battery models) to prevent accidental starting. Tilt the mower onto its side with the carburetor/battery side up to access the rear wheels.
- Remove Old Wheels: Locate the retaining nut or bolt securing the old wheel to the axle. Use the appropriate wrench or socket to loosen and remove it. Carefully slide the old wheel off the axle.
- Inspect and Clean: Before installing the new wheels, inspect the axle for any debris, rust, or damage. Clean the axle thoroughly with a cloth.
- Install New Wheels: Align the new Toro 140-2350 rear drive wheel with the axle. Ensure the geared side of the wheel (if applicable to your model's drive system) faces inward towards the mower body. Slide the wheel onto the axle until it is fully seated.
- Secure the Wheels: Reinstall the retaining nut or bolt onto the axle. Tighten it securely, but do not overtighten, as this can damage the wheel or axle. Ensure the wheel spins freely but has no excessive wobble.
- Test Operation: Once both wheels are installed, return the mower to its upright position. Reconnect the spark plug wire or reinstall the battery. Briefly engage the self-propel mechanism (if applicable) to ensure the new wheels are functioning correctly and engaging with the drive system.

Operating Considerations
While these wheels are designed for durability, proper operating practices contribute to their longevity and the overall performance of your lawn mower.
- Terrain: Avoid operating the mower on excessively rough or rocky terrain that could cause undue stress or damage to the wheels.
- Obstacles: Be mindful of obstacles such as tree roots, large stones, or debris that could impact the wheels.
- Storage: When storing the mower for extended periods, ensure it is on a flat, stable surface to prevent uneven pressure on the wheels.
Maintenance
Regular inspection and basic maintenance will help extend the life of your Toro rear drive wheels.
- Cleaning: After each use, remove grass clippings, dirt, and debris from the wheels and around the axle area. A stiff brush and water can be used, but avoid high-pressure washing directly on bearings or seals.
- Inspection: Periodically inspect the wheel tread for excessive wear or damage. Check for cracks in the plastic or rubber components. Ensure the wheels are securely fastened to the axle and that there is no excessive play.
- Lubrication: While these wheels are generally maintenance-free, if your mower's axle system requires lubrication, follow your mower's specific manual for appropriate lubrication points and types. Avoid lubricating the wheel's tread.
Troubleshooting
This section addresses common issues related to the rear drive wheels.
| Problem | Possible Cause | Solution |
|---|---|---|
| Wheel Wobbles or is Loose | Loose retaining nut/bolt; Worn axle or wheel hub. | Tighten the retaining nut/bolt. If wobble persists, inspect the axle and wheel hub for wear and replace components as necessary. |
