Does your Toro self propelled lawn mower start and run fine, but the wheels just won’t turn when you squeeze the handle? This is a common problem—and most of the time, you can fix it yourself without special tools or costly repairs. Here’s how to quickly diagnose why your Toro isn’t moving and get your mower driving like new again.
Quick Picks: Most Common Reasons a Toro Self Propelled Mower Won’t Move
- Drive Cable Issue: The cable that connects the handle to the transmission may be loose, stretched, disconnected, or broken.
- Drive Belt Problem: A worn, broken, or slipped belt under the deck can stop the self propel system from working.
- Worn or Damaged Drive Wheels: The rubber tread or plastic gears inside the wheels can strip or wear out.
- Transmission Failure: The gearbox that drives the wheels can fail with age or lack of maintenance.
- Obstructions or Debris: Grass, sticks, or debris jammed around the wheels, axles, or under the deck can stop movement.
- Improper Handle Operation: The self propel lever or bar must be held fully down and engaged—if not, wheels won’t move.
- Wheel Height Not Set Properly: If set too high or low, the drive may not engage properly.
Buyer’s Guide: What You’ll Need to Troubleshoot and Fix

- Owner’s manual: For diagrams and part numbers.
Step-by-Step: How to Fix a Toro Self Propelled Mower That Won’t Move
1. Inspect and Test the Drive Cable
- Squeeze the self propel handle and watch the cable on the side of the mower.
- If it doesn’t move, is loose, or broken, replace or adjust the cable (usually a simple DIY job).
- If it’s stretched, use the adjuster screw (often near the handle) to tighten.
2. Check the Drive Belt
- Tip the mower back (after disconnecting the spark plug for safety) and look for the belt under the deck.
- If the belt is off the pulley, frayed, cracked, or broken, replace with a new belt matched to your model.
- Make sure the belt tension is firm, not loose or sagging.
3. Inspect the Drive Wheels
- Remove the wheels and check the gears inside for wear or stripped teeth.
- If the rubber tread is worn smooth or the internal gears are stripped, replace the drive wheels.
4. Clear Obstructions and Debris
- Check around the wheels, axle, and under the deck for packed grass, mud, or sticks.
- Clear out anything blocking the wheels or drive system.
5. Test the Transmission
- If the cable, belt, and wheels are all fine but the wheels still don’t move, the transmission may have failed.
- Transmission replacement is more involved—contact Toro support or a small engine repair shop for help if you suspect this issue.
6. Double Check Handle Operation and Wheel Height
- Make sure you’re holding the self propel handle fully down as you push.
- Adjust wheel height so the drive system engages correctly—not too high or low for your grass and terrain.

Frequently Asked Questions
How do I know if my Toro’s drive cable is broken?
If you squeeze the self propel handle and the cable doesn’t move, or you see a frayed or snapped wire, it’s time to replace the cable.
Can I replace a Toro drive belt myself?
Yes—most belts can be replaced at home with basic tools. Follow your owner’s manual or a Toro belt replacement video for guidance.
Why do my Toro’s wheels spin but the mower doesn’t move?
The drive wheels may be stripped or worn, or the transmission gears could be slipping inside. Check both parts for wear.
How often should I service the self propel system?
Clean around the drive system after every few mows and inspect cables, belts, and wheels each season for wear or damage.
What if none of these fixes get my mower moving?
If you’ve checked and replaced the cable, belt, and wheels and your Toro still won’t move, the transmission may be the culprit. Contact Toro service or a small engine technician for help.
