What It Is

The 112-8818 brake cable is a replacement control cable that engages and disengages the blade brake on Toro Lawn-Boy 20in and 22in walk-behind mowers, specifically models with mulching or rear-discharge decks. It’s the mechanical link between the handle-mounted brake lever and the blade brake system.

Fitment & Compatibility

• Exact OEM part number: 112-8818 (Lawn-Boy/Toro genuine). Aftermarket equivalents may vary in length or end fittings.
• Fits these model numbers: 10603, 10604, 10642, 10646, 20314, 20316, 20323, 20330, 20331, 20338, 20339, 20371.
• Deck sizes: 20in and 22in. Confirm your mower’s deck size and model number (stamped under the seat or on the deck near the rear wheel).
• What to measure: Overall cable length (approx. 40-45 inches) and the exact distance between end fittings (hook-to-hook). Compare to your old cable before ordering.
• Not universal: Will not fit other Toro or Lawn-Boy models outside the listed numbers, even if deck size matches.

Key Things to Know

• Quality concern: The single 1.0-star rating likely reflects a poor aftermarket variant. Genuine OEM Lawn-Boy cable is more reliable and fits without modification.
• Installation: Requires removing the old cable from the handle and brake arm, then routing the new cable through the same path. No special tools needed, but a pair of pliers helps with clip removal.
• Common gotcha: The cable housing can kink if bent sharply during routing. Use gentle curves and avoid pinching under handle bolts.
• Check the brake itself: If the brake band or pads are worn, a new cable alone won’t fix a weak brake. Inspect the brake assembly before replacing the cable.

Should You Buy It

Buy it if you have one of the listed Toro Lawn-Boy models and your brake cable is frayed, stretched, or broken. Stick with the genuine OEM part (not aftermarket) to avoid fit issues. If your mower’s brake still feels weak after cable replacement, the brake drum or pad needs attention, not just the cable.
