Honda makes some of the best, most reliable lawn mowers around, but even top brands can have issues over time. If your Honda self propelled lawn mower is not working—maybe the wheels won’t turn, the drive feels weak, or the mower just drags—it’s almost always fixable at home with basic tools and a little patience. This complete guide will show you how to diagnose, repair, and prevent the most common problems with Honda’s self propel system.
Quick Picks: The Most Common Causes of Honda Self Propelled Problems
- Broken or Slipped Drive Belt: If the belt connecting the engine to the wheels is snapped, worn, or off the pulley, the self propel won’t engage.
- Stretched or Broken Drive Cable: The cable from the handle to the transmission can stretch over time or snap completely.
- Worn Transmission or Pulley: Honda’s durable gearboxes can wear out or seize up after many seasons of use.
- Jammed or Damaged Wheels: Clogged, stripped, or locked wheels stop the mower from moving forward.
- Loose or Misadjusted Control Lever: The self propel lever/cable might have too much slack, so it never fully engages the drive.
- Engine Power Issues: If your mower engine bogs down, even a healthy drive won’t move the wheels well.
Buyer’s Guide: What to Check First (and What You’ll Need)
- Inspect the Drive Belt: Look underneath for cracks, frays, or if the belt has slipped off the pulley.
- Check the Drive Cable: Squeeze the self propel handle—if it feels loose or doesn’t snap back, you may need to adjust or replace the cable.
- Examine the Transmission: Listen for grinding or feel for resistance when the wheels should be moving. Oil leaks or noises suggest gearbox problems.
- Wheel Condition: Remove grass buildup, check for stripped gears, or bent axles on the drive wheels.
- Engine Tune-Up: Replace spark plug, clean air filter, and change oil regularly for best performance.
- Tools Needed: Phillips and flathead screwdrivers, socket set, pliers, replacement belt/cable if needed, cleaning brush, gloves.
Step-by-Step Fix: How to Repair a Honda Self Propelled Lawn Mower That Won’t Move
1. Safety First
- Always disconnect the spark plug wire before making repairs.
- For electric models, remove the battery before working.
- Work on a flat, stable surface and wear gloves to protect your hands.
2. Inspect and Replace the Drive Belt
- Tip the mower back with the air filter facing up (to avoid oil/gas leaks).
- Look underneath at the drive belt connecting the engine pulley to the transmission near the wheels.
- If the belt is worn, cracked, broken, or off its pulley, replace it with a new OEM Honda belt.
- Belts are inexpensive and can be changed at home in 20-30 minutes with basic hand tools.
3. Check the Drive Cable and Control Lever
- Follow the cable from the handle to the transmission housing at the deck.
- If the cable is slack, try tightening the adjustment nut near the handle. If broken or heavily frayed, replace the cable.
- Test the lever action. It should have some tension and fully return when released.
4. Examine the Transmission and Wheels
- Lift the drive wheels off the ground and engage the self propel handle.
- Spin the wheels by hand: they should resist turning when the handle is squeezed. If not, the transmission may be worn out and need replacement.
- Listen for grinding noises or look for leaking oil—these are signs of internal gearbox failure.
- Remove any built-up grass or debris from around the wheels and transmission housing.
5. Clean and Lubricate the Wheels and Axles
- Clean off any clumps of grass or dirt that could jam the wheels.
- Spray a light lubricant on the axle and gears (avoid over-lubricating, which can attract more debris).
- Check for stripped plastic gears or a wheel that wobbles—replace any damaged parts.
6. Adjust the Drive Control
- Locate the cable adjustment screw or nut (usually near the handle).
- Tighten if the drive feels weak or doesn’t engage right away.
- After adjusting, test the mower to make sure the self propel engages as soon as you squeeze the lever.
7. Tune Up the Engine
- If your mower bogs down in thick grass or the drive feels weak even when everything else checks out, do a quick tune-up: replace the spark plug, clean/replace the air filter, and change the oil.
- A strong engine helps power the self propel system.

Frequently Asked Questions
Why do the wheels spin when the mower is off the ground but not when it’s on the grass?
This usually means the drive belt is slipping under load, the drive cable is too loose, or the transmission is failing. Start by checking belt and cable tension.
Can I still use my Honda mower if the self propel doesn’t work?
Yes, most Honda self propelled mowers can be pushed manually if the drive system is disengaged or not working. It may be heavier than a true push mower, but still usable for small lawns.
How often should I replace the drive belt and cable?
These parts typically last 3-5 seasons with average use, but should be inspected every year and replaced at the first sign of wear or damage.
What regular maintenance prevents Honda self propel issues?
- Clean underneath the deck after every use to prevent grass buildup around the drive system.
- Inspect the drive belt, cable, and wheels each season.
- Keep wheels and axles lightly lubricated, but don’t overdo it.
- Give the engine a yearly tune-up for best drive performance.
Is it expensive to fix Honda self propelled mowers?
Most repairs—like belt, cable, or wheel replacement—are inexpensive and can be done at home. Transmission replacement is more involved but still costs far less than a new mower.
Conclusion
When your Honda self propelled lawn mower isn’t working, don’t panic! With a little inspection, basic tools, and the right replacement parts, you can often get back up and running in less than an hour. Focus on the drive belt, cable, wheels, and engine health for reliable self propel performance every mowing season. Regular cleaning and annual tune-ups will keep your Honda running strong for years to come.
