Things to know: John Deere S120 Problems
One of the problems was the New John Deere S120 belt issue, which happened to one of the members of the Reddit forum. One of the usernames, “whisk,” responded to /r/JohnDeereLawnMachines/, where, according to his confession, while mowing the grass in the yard, the grass-cutting belt suddenly came loose.
I loosened one of the wheels, reinstalled it, and finished the cut. On the third grass cut, the blade would not engage, and apparently, the belt came loose again. I put it back on, the belt broke, and now I’m going to replace it. I watched a few videos and installed a new one, and everything was tight again.

John Deere S120 Problems & Solutions
Usually praised for performance and dependability is the John Deere S120 Lawn Tractor. Some users, meanwhile, have specifically highlighted particular problems:
- Engine Performance Problems: Notes of instances of the engine stalling or running poorly. Typical reasons are clogged fuel lines, malfunctioning spark plugs, or unclean air filters. Frequent maintenance including spark plug and air filter replacement helps to minimize these problems.
- Starting Problems: Some users have found difficulty starting the tractor, often resulting from improperly engaged safety switches or problems with the starter solenoid. Examining the starter solenoid and making sure all safety switches are in their proper alignment will help to fix these issues.
- Mower Deck Concerns: Unequal cuts or scalping have been reported from the mower deck, which fails to follow the curves of the grass. Changing the deck height and guaranteeing it is levelled will help with mowing performance.
Some consumers have encountered issues with the Easy ChangeTM 30-Second Oil Change System and the mower’s belts. Regular belt wear inspections and proper oil change system use help avoid these problems.
Regular maintenance and quick attention to anomalies will improve the lifetime and performance of your John Deer S120 lawn tractor.
Which Jhone dere to Avoid
I’m considering buying a used John Deere lawn tractor (under 1k) and could use some advice. I’ve heard that some of the older models are good. I’ve also heard to avoid the boxed models sold at HD and Lowes. So, my question is whether there are older models that are also unreliable. For example, I often see STX38 for short money. A list of reliable and unreliable JDs (or other brands) is appreciated. Thanks, Mike

How Long Do Tractors Last?
In general, a tractor’s average lifespan is 4,000 hours or more. This is the same as the tractor’s low service life, almost the same as the warranty period.
If you buy a used tractor, consider the number of hours compared to the warranty period. If the warranty is valid for 2,000 hours, you can be sure that the machine will work for more than 2,000 hours. The machine is still new if the machine has been running for 300 hours and the warranty is valid for 2,000 hours.
Because it is not uncommon to see used tractors that have worked for 300 hours, a small farm may only work 20 hours per year.
