Frequently Asked Questions

How do I know if my Toro Personal Pace belt is worn out?
Signs of a worn belt include inconsistent walking speed, slipping during acceleration, visible cracks or fraying, glazed appearance, or the belt feeling loose when the mower is off.
Why does my Toro mower speed up and slow down randomly?
This is typically caused by a worn drive belt that slips under load, a weak tension spring, or debris caught in the drive system. Most commonly, the belt needs replacement.
How often should I replace the Personal Pace drive belt?
Drive belts typically last 2-4 mowing seasons depending on usage and conditions. Replace when you notice speed inconsistencies, visible wear, or every 3 years as preventive maintenance.
Can I still use my Toro mower if the Personal Pace isn't working?
Yes, you can push the mower manually, but it will require more effort. However, it's best to fix the Personal Pace system promptly to avoid strain and maintain proper mowing efficiency.
What causes Toro Personal Pace belts to wear out quickly?
