Why Does My John Deere Lawn Mower Keep Dying?
If you have a John Deere lawn mower that keeps dying, there are a few potential causes. First, the spark plug may need to be replaced. Second, the air filter may be dirty and need to be cleaned or replaced.
Third, the fuel may be old and stale and need to be fresh. Finally, the carburetor float may be stuck and need to be replaced. If you have checked all of these potential causes and your John Deere lawn mower still keeps dying, it is likely that there is a more serious issue with the engine that will require professional repair.
Why is My John Deere Blowing White Smoke?
If your John Deere tractor is blowing white smoke, it could be due to a number of different factors. Let’s take a look at some of the most common reasons why this might be happening.
One possibility is that the engine is running too rich.
This means that there is more fuel being burned than there should be, and it can cause white smoke to come out of the exhaust. If you think this might be the case, you can try adjusting the carburetor to lean out the mixture slightly.
Another possibility is that water has gotten into the combustion chamber somehow.
This could happen if the tractor was stored in a damp place or if it was driven through deep puddles. If water gets into the cylinder, it will start to steam when it hits the hot piston, and this can cause white smoke. To fix this problem, you’ll need to drain all of the fluids from the engine and then have it professionally inspected for leaks.
Finally, white smoke can also be caused by oil burning in the engine. This usually happens when worn piston rings allow oil to leak past them and into the cylinder where it’s burned along with fuel. If this is what’s causing your tractor to blow white smoke, you’ll need to have your engine rebuilt or replaced.
If your John Deere tractor is blowing white smoke, don’t panic! There are a few different things that could be causing it, but fortunately they’re all relatively easy to fix. Just take a look at what might be causing the problem and then take care of it accordingly.

The first problem that many LX178 owners face is starting issues.
If your tractor won’t start, then the first thing you should check is the battery. Make sure that the terminals are clean and free of corrosion. If the battery looks good, then check the starter solenoid and ignition switch.

Dear Michael,
Thank you for sharing your experience and insights regarding the John Deere LX178 lawn mower. It’s great to hear that you have found it to be a reliable machine that has served you well over the years.
Your maintenance routine, including changing the fuel pump, spark plugs, and oil filter regularly, shows your dedication to keeping the mower in good working condition. Using John Deere oil and filter and keeping the air cleaner clean are excellent practices for optimal performance.
Regarding the oil seepage issue on one valve cover, it’s unfortunate that replacing the gasket didn’t completely resolve the problem. Sometimes, these small leaks can be persistent, and as long as they don’t affect the overall performance of the mower, leaving it alone might be a reasonable solution.
You mentioned replacing the drag link once and now needing to replace it again. It’s understandable that you would have preferred it to be greaseable for easier maintenance. This feedback about the drag link design is valuable and might be worth sharing with John Deere or considering aftermarket options if available.
Additionally, the weather-checked and leaking rear tire, along with the worn and almost bald tires, are signs of wear and tear that commonly occur over time, especially in sandy environments. Replacing them would undoubtedly improve traction and overall performance.
It’s commendable that you have had the mower deck welded a few times due to the sandy conditions in your area. This proactive approach demonstrates your commitment to extending the life of the mower and making necessary repairs when needed.
Lastly, it’s remarkable to hear that despite these challenges, your LX178 continues to serve you well. It’s a testament to the durability and longevity of the machine. If you ever decide to replace it in the future, it’s clear that you’ve gotten your money’s worth.
Thank you for taking the time to share your experience and provide valuable feedback. Your comment will undoubtedly help other readers gain a better understanding of the LX178’s performance and potential areas for improvement.
Happy mowing!
Best regards,
Jerry
