133-8158 Blade Brake Cable Kit Compatible with Toro 30" Timemaster Mower 20199 20200 20975 20977 Replace 120-6243

What It Is

The 133-8158 Blade Brake Cable Kit is a replacement cable assembly for the blade engagement system on Toro 30" TimeMaster mowers. It connects the control handle to the blade brake mechanism, allowing you to safely engage and disengage the blades.

Fitment & Compatibility

This cable kit fits Toro TimeMaster models 20199, 20200, 20975, and 20977 (all with 30-inch decks). It replaces OEM part 120-6243. Before buying:

• Check your model number – it must be one of the four listed above. The model is on a sticker under the seat or on the frame near the engine.
• Measure the cable length – the original cable is roughly 60 inches. If yours is different, this kit won’t route correctly.
• Verify the brake assembly – this cable only works with the stock blade brake system. Aftermarket or modified brake levers may require a different cable.
• OEM vs aftermarket – this is an aftermarket part. It should match OEM dimensions, but check the cable end fittings (typically a ball end at the handle and a threaded barrel at the brake) to confirm.

Key Things to Know

• Installation difficulty – moderate. You’ll need basic tools (wrenches, pliers, maybe a screwdriver) and about 30–45 minutes. The cable routes along the handlebar and under the deck.
• Common gotcha – the cable housing is plastic-lined. If it kinks during installation, the cable will bind and the brake won’t release fully. Route it gently and avoid sharp bends.
• Quality note – this is a budget-friendly aftermarket cable. It works, but the OEM cable (120-6243) often has slightly smoother action and longer life. Expect 1–2 seasons of regular use.
• Check the brake spring – if the brake feels stiff or the cable snaps soon after install, the brake spring may be worn. Replace both at the same time.

Should You Buy It

Buy this if you need a quick, low-cost fix for a broken or frayed blade brake cable on your Toro TimeMaster and you’re comfortable with a moderately challenging installation. It’s a good value for the price, but if you want the best durability and easiest installation, stick with the OEM cable.
