Yes, you can use car ramps to change a lawn mower blade, but it is not the safest or most recommended method. The primary risk involves stability; car ramps are designed for vehicles with a much wider wheelbase and significant weight. A riding mower can easily tilt or slide off the ramps, creating a serious crush hazard. For a safer alternative, dedicated lawn mower lift stands or sturdy jack stands paired with wheel chocks are strongly advised.
The main challenge is the narrow track width of most riding mowers. Their wheels are set much closer together than a car's, making them unstable on ramps designed for a car's wider stance. Even a slight shift in weight can cause the mower to tip sideways. Furthermore, the traction on metal or plastic ramps may be insufficient, leading to the mower sliding backward.
If you must proceed, the process is meticulous. Always disconnect the spark plug wire to prevent any accidental engine start. Engage the parking brake and securely chock the rear wheels. Carefully drive the mower's front wheels onto the ramps. Before getting underneath, perform a stability test by gently rocking the mower. The access provided is also often limited, making it difficult to properly torque the new blade.
For comparison, here are common methods and their safety profiles:
| Method | Stability | Ease of Use | Approximate Cost | Risk Level |
|---|
| Lawn Mower Lift | Excellent | High | $100 - $300 | Low |
| Hydraulic Floor Jack & Jack Stands | Good | Medium | $50 - $150 (for stands) | Medium-Low |
| Car Ramps | Poor | Low | $50 - $100 (if you own them) | High |
| Tilting Mower on its Side | Fair (for push mowers) | High | $0 | Medium (risk of fluid leaks) |
Ultimately, while possible, the significant safety risks outweigh the convenience. Investing in the proper equipment is a wise decision for your personal safety.
