3. Wheel Is Not Moving
If the wheels of your John Deere 100 series lawn tractor are not moving, the transmission system may be faulty.
This problem can be caused by several reasons, including faulty transmission gear or worn drive belts.
To deal with the stopped wheels, examine the drive belts for any signs of wear, damage, or looseness.

Refer to the owner’s manual for the correct size and type of replacement belts, and follow the instructions for proper installation.
Another solution for this problem can be by replacing or repairing the transmission gear.
If you notice any issues with the gear, replace it immediately. You may need to seek the help of a professional mechanic for this.
4. Loss of Power
Your John Deere 1000 series may lose power while working, which is quite frustrating.
The most common reasons responsible for this problem include clogged air filters, dirty fuel filters, and a faulty spark plug.
The spark plug ignites the fuel and air mixture while the air and fuel filter ensures the mixture is clean.
A problem with any one of these might result in loss of power in your John Deere 1000 series or any other lawn tractor.
Before going for the solution, you need to identify the problem. Check whether it is due to a clogged air filter, a dirty fuel filter, or a faulty spark plug.
If the root cause for the problem is an air or fuel filter, consider replacing it with a new one. You may also consider cleaning the air filter if it’s not too dirty.
Similarly, inspect the spark plug to see any damages. Even if there is no clear sign of damage, try replacing the spark plug to see if it works.
5. Unusual Noises
Are you experiencing some horrible squealing noises while driving your John Deere 100 series?
Worn transmission gears, damaged bearings, or loose bolts can often result in such noises.
Worn-out gears can produce a grinding or whining sound, while worn bearings can produce a humming or whirring noise.
Additionally, if you hear a squealing or chirping sound, it means that the belts have worn out due to wear and tear.
If you notice any worn-out gears or bearings, replace them immediately. Similarly, replace the belts if they are loose or worn out.
Moreover, regular maintenance of the transmission system can help prevent unusual noises from occurring.
6. Leaking Transmission Fluid
Another common transmission problem in a John Deere 100 series lawn tractor is leaking transmission fluid.
A damaged seal or gasket can cause fluid to leak, while a damaged pan can cause fluid leakage from the bottom.
If the transmission fluid level is low or you notice a leak, inspect these components and replace them as necessary.
Following the manufacturer’s recommended maintenance schedule can help prevent transmission fluid leaks.
