John Deere L120 Transmission Problems
If you’re a John Deere L120 owner, then you may have experienced some transmission problems. Here’s a detailed look at what might be causing your issues and how to fix them. The John Deere L120 is a lawn tractor that was first introduced in 2002.
It featured a hydrostatic transmission and was powered by a 20-horsepower Briggs & Stratton engine. The L120 was part of the John Deere LA series which also included the L100, L110, and L130 models. One common issue that owners of the John Deere L120 have reported is difficulty shifting gears.

You may also need to bleed the air out of the system by opening bleeder valves located on the transmission housing.
Another problem that has been reported is leaks coming from either the front or rear of the transmission housing. In most cases, these leaks are due to damaged seals or gaskets and will require replacement parts to fix.

John Deere L120 Electrical Problem

Next, check all of the wiring harnesses to make sure they’re properly connected and not damaged. If everything looks good there, then the problem may be with the ignition switch or starter solenoid.
These components can sometimes go bad and will need to be replaced if they are the cause of your electrical problems.
John Deere L120 Transmission Slipping
John Deere’s L120 lawn tractor features a hydrostatic transmission, which offers an infinite number of speeds in both forward and reverses gears.
This makes it ideal for mowing your lawn or other tasks that require precise speed control. However, hydrostatic transmission can develop problems over time, one of which is known as “transmission slipping.”
If you notice that your John Deere L120 lawn tractor seems to be losing power or “slipping” out of gear, there are several potential causes. One possibility is that the hydrostatic fluid has become low. Check the level of fluid and add more if necessary.
Another possibility is that the filter for the hydrostatic system is dirty or clogged and needs to be replaced. If neither of these solutions solves the problem, then it’s possible that the transmission itself is starting to fail. This is a serious issue that will require professional repair or replacement.
If you suspect this is the case, take your John Deere L120 lawn tractor to a qualified technician as soon as possible for diagnosis and repairs.
John Deere L120 Moves Slow
John Deere L120 Moves Slow The John Deere L120 is a great lawn tractor for those who have a medium-sized yard and need to cut grass on a regular basis. However, some users have complained that the L120 moves slowly, making it difficult to get the job done in a timely manner.
If you’re experiencing this issue, there are a few things you can do to help speed up your tractor. First, make sure that the transmission is in good working order. If it’s not, then it could be causing the slowness.
You should also check the drive belt to see if it’s worn or damaged. If either of these is an issue, then you’ll need to take your tractor to a John Deere dealer or qualified repair shop to have them fixed. Another thing you can try is adjusting the rear wheels.
The rear wheels on the L120 are adjustable and moving them closer together, will help increase traction and therefore speed. Simply loosen the nuts on each wheel until they’re able to move freely, then adjust them as needed and retighten the nuts when finished.
If you’ve tried all of these things and your John Deere L120 still moves slowly, then there may be an issue with the engine itself.
In this case, you’ll need to take it to a qualified repair shop for further diagnosis and repairs.
John Deere L120 Slow Reverse
If you’re having trouble with your John Deere L120 lawn tractor moving in reverse, there are a few things you can check. First, make sure the transmission is in the correct gear. The L120 has six forward gears and one reverse gear, so if the transmission is in any of the forward gears, the tractor won’t move in reverse.
Next, check the PTO (power take-off) switch. This switch must be engaged in order for the tractor to move in reverse. The PTO switch is located on the dash panel, near the steering wheel.
If neither of these solutions solves the problem, there may be an issue with hydrostatic transmission. This type of transmission uses hydraulic fluid to power the wheels, and if there’s a leak or other problem with the hydraulics, it can cause problems with moving in reverse.
If you think this might be the case, it’s best to take your tractor to a qualified John Deere dealer or service center for diagnosis and repair.

FAQ

If you have trouble starting your John Deere L120, the problem could be your spark plug. If you’ve tested the spark plug and it’s good, then you will want to make sure that the flywheel key is intact or has not broken.
There may also be dirt in your carburetor or a bad fuel line. A loose or dirty gas cap is another possible culprit that can cause the engine to misfire. If this does not solve your problem, then replace your flywheel.
What should I do if my John Deere L120 is smoking?
If your John Deere L120 is smoking, this could mean that you have oil on your spark plug. If you clean your spark plug, this should help alleviate the problem. This may also be due to burned valves or valve guides. These parts will need to be replaced if you want the smoke to go away.
When to change spark plugs on a John Deere L120 mower?
If your John Deere L120 mower is smoking, you may need to change the spark plugs. The average life of a spark plug will last between 30-40 hours depending on the type of engine you have.
For example, an L100 engine has a different type of ignition system than an L120 or L130 engine, which can make the spark plugs last longer. If you regularly clean your John Deere L120 mower’s air filter and fuel filter then this can also extend the life of your spark plug.
