Frequently Asked Questions

How do I know if my Toro TimeMaster blade brake is working properly?
The blade brake should stop the blades within 3 seconds of releasing the bail handle. You should hear the engine continue running while the blades stop spinning. If blades don't stop or take longer than 3 seconds, the brake needs attention.
Can I still use my TimeMaster if the blade brake doesn't work?
No, never use a mower with a faulty blade brake. This is a critical safety feature required by law. Operating without a working blade brake is extremely dangerous and violates safety regulations.
How often should I check my TimeMaster blade brake?
Test the blade brake before each use by starting the mower, engaging the blades, then releasing the handle. The blades should stop within 3 seconds. Also perform a visual inspection of the brake cable monthly during mowing season.
What causes Toro TimeMaster brake cables to stretch?
Brake cables stretch due to normal wear, exposure to weather, improper storage, and repeated use. Cables naturally elongate over time, especially if the mower is stored in damp conditions or if the cable wasn't properly lubricated.
How much does it cost to replace a TimeMaster brake cable?
Brake cables typically cost $15-30 for the part. If you need BBC replacement, expect $80-150 for parts plus labor if professionally installed. Cable adjustment is often free if you do it yourself.
