Does this part fit my model?
Need help finding your model number?This rear arm spring is a genuine OEM replacement designed for Toro and Lawn-Boy walk-behind lawn mowers. It is part of the rear height-of-cut adjustment system, providing the tension needed to keep the rear wheel arms balanced and the mowing height securely set during operation. Manufactured for durability and proper spring tension, it’s an ideal replacement when corrosion, fatigue, or loss of tension causes uneven cutting height or prevents the rear deck from staying locked at the selected setting.
